Garden Care — Fruit Trees & Lawn

Santa Clara 95050 · USDA Zone 9b / Sunset 17 · Clay-leaning soil, wet winters, dry summers
Lemon · Fuyu Persimmon · Nectarine · Plum · Fig · Apricot · Roses & flower plants · Grass lawn
Plan checked against UC ANR / UC IPM guidance and discussed with Argon (Gemini) — Nov 1, 2026

🌧️ The one idea that explains most of this yard: the trees and the lawn are one system. Tree roots run 1.5–2× wider than the canopy — straight under the grass. Frequent shallow lawn sprinklers + high-nitrogen lawn food push the apricot into a fruitless green monster, keep fig/citrus roots shallow and stressed in clay, and never reach deep tree roots. Fix the watering split — lawn shallow, trees deep and infrequent — and half the problems below get better.

🚨 Do these now — November

Clean up under every stone-fruit tree

Rake fallen leaves and pick every dried “mummy” fruit out of the apricot, nectarine and plum — brown rot overwinters there. Trash them, don’t compost them.

Give the fig its mulch ring

Clear grass/weeds in a 6–8 ft circle around the fig trunk. Lay ~2 in compost + 4 in wood chips, kept 6 in away from the bark. This is step 1 of the fig rescue (below).

Run the 10-minute fig inspection

Checklist is in the fig section below. Note what you find — it decides whether the fig’s problem is water, gophers/roots, or disease/variety.

Book / plan the late-November dormant spray

After leaf fall: fixed copper + horticultural oil on nectarine and plum (peach leaf curl + shothole prevention). Apricot gets copper for shothole too — but see the apricot rules below, it is not on the same schedule as the others after that.

Stop feeding the lemon — and don’t prune it

No citrus fertilizer or pruning Sep–Jan. Late nitrogen pushes tender growth that freezes on our 28–32°F Dec–Jan nights.

Lawn: fall feed, then ease off water

Slow-release winterizer in early Nov if you feed. Drop watering to ~1×/week, off entirely in rainy weeks. Mow at 3 in.

Do NOT prune the apricot this winter

Winter pruning wounds let in Eutypa dieback fungus in wet weather. Apricot pruning is a late July–mid August job only. Details below.

Lemon: do the 2-minute black-spot test

Black on the leaves and the lemons is most likely sooty mold, not a spot disease — the wipe test in the lemon alert section below settles it in 2 minutes, and the treatment is insects + ants, not fungicide.

Roses: stop deadheading and stop feeding

Leave the last autumn blooms to form hips — that signals the bush to slow down for winter. Rake up black-spotted/rusted fallen leaves into the trash (not compost). Do NOT do the big rose prune yet — that’s January. Only shorten a very tall cane if wind could rock it loose.

🌟 The 6 golden rules

Water trees deep and infrequent: a slow soak out to the drip line every 10–21 days in summer (18–24 in deep), never daily sprinkles. Trees survive a dry summer — they just abort/shrivel the fruit.
Mulch every tree: 3–4 in wood chips over the root zone, 6 in clear of the trunk. Never mound soil/mulch against a lemon or fig trunk — crown rot in clay.
No nitrogen for apricot and fig (compost ring only) until fruiting balances. Nitrogen = leaves, not fruit, for these two.
Apricot is the exception to every winter rule: prune in summer, copper only at leaf-fall and at red-bud stage, never after blossoms/leaves open.
Never spray anything in bloom — protect the bees, and dormant sprays only work before bud swell anyway.
Thin fruit hard: nectarines to ~6 in apart, plums to ~4 in apart when marble-size. Unthinned trees make small, poor fruit and break limbs.

🍑 Problem tree #1 — Apricot: huge tree, ~10 apricots

Why this is fixable

Santa Clara was once the apricot capital of the world (Blenheim country). A healthy mature apricot here should carry hundreds of fruit. ~10 on a huge tree means the tree is stuck in a vegetative loop + its February bloom is failing — not that the climate can’t do it.

🥇 #1 — Lawn nitrogen & water + a shaded-out canopy

Apricot roots spread under the lawn and gorge on every lawn feeding and sprinkler cycle. Add any winter topping/heading cuts and the tree answers with 4-ft water sprouts on top.
That dense top shades the interior, and the short fruiting spurs die in the shade — spurs need real sun to form next year’s flower buds, and they only live 3–5 years, so they must constantly be renewed in the light.
Fix: zero nitrogen fertilizer within 15–20 ft of the trunk. Then late July–mid Aug 2027 (dry window): thin out 25–30% of the upper canopy with thinning cuts only — water sprouts cut back to their origin, never topped. Open “skylights” so sun hits the lower spurs. Repeat lightly each summer.

🥈 #2 — February bloom wipeout

Apricots bloom mid-Feb to early Mar, right in late-winter rain. Bees don’t fly below ~55°F or in rain, and brown rot blossom blight infects open blossoms in wet weather — hundreds of potential fruit die before you ever see them set.
Fix: November cleanup of mummies/dead twigs (above). Fixed copper after leaf fall for shothole, and again at red-bud / “popcorn” stage in early Feb, just before petals open. Apricots are copper-sensitive after budbreak — never copper once leaves/blossoms are open.

🥉 #3 — Chill hours / variety

Low-chill types like Blenheim (~400–500 hrs) still fruit here; high-chill types (Moorpark, Tilton, 600–800+ hrs) bloom sparsely and raggedly after warm winters — and Santa Clara winters are getting warmer (many recent winters ~350–450 hrs).
The February test tells you which problem you have: if the tree explodes with thousands of blossoms, chill is fine — the issue is #1/#2. If it opens only scattered flowers while leafing out unevenly, chill/variety is a real factor and expectations (or a low-chill graft) need a rethink.

Also remember: apricot fruit grows on 1-year wood + spurs; wood is brittle — don’t let long limbs carry heavy loads. Cut out any limb that wilts/dies back in spring-summer (possible Eutypa) at least 1 ft below the canker, in summer only.

🫒 Problem tree #2 — Fig: small, dry fruit, unhealthy tree

The key read

A healthy fig in Santa Clara should be nearly indestructible. Small dry fruit plus a sickly-looking tree points down — to roots and water delivery — not to excess fertilizer. An over-fed fig looks the opposite: huge, lush and dark green. This tree looks starved/stressed, so the fix is root health + deep water, not withholding care.

Ranked causes

Summer water deficit in compacted clay. 10-minute sprinklers wet the top 1–2 in; clay below bakes hard. In the final 2–3 weeks of ripening (“fruit swell”), a thirsty fig pulls moisture back out of the fruit — leaving small, woody, bone-dry figs. Inconsistent watering also causes fruit drop and splitting.
Root damage: pocket gophers love fig roots and can quietly remove much of the root system (sparse canopy, dry fruit). The opposite also happens in clay: a low spot that pools lawn runoff suffocates roots / root rot.
Fig mite + fig mosaic virus, or scale: mottled yellow leaf blotches, russeted dry fruit interiors, early leaf drop; gray/brown bumps on twigs = scale.
Variety trap: if June (breba) figs are good but the Aug–Sep main crop stays small, dry and drops, it may be a San Pedro/Smyrna type whose main crop needs wasp pollination that Santa Clara backyards don’t have. Common types (Mission, Brown Turkey, Kadota…) don’t need pollination.
Picking too early makes it worse — figs do not ripen off the tree. Pick only when the neck droops and the fruit hangs soft.

🔍 The 10-minute fig inspection — do this first

Trunk wobble + gopher check (2 min)

Push the trunk firmly — any spongy give in a mature tree? Crescent dirt mounds within 15 ft? Yes → suspect gophers.

New-shoot length (2 min)

Healthy: 8–18 in of new wood this year (find the ring scar where spring growth started). Only 1–3 in → roots are starved or damaged.

Soil probe at the drip line (3 min)

Push a long screwdriver in, 4–6 ft from the trunk. Stops dead at 2 in = concrete-dry clay. Comes up foul, soggy and gray = waterlogging. Either extreme is a diagnosis.

Leaf + twig check (2 min)

Yellow mosaic blotches? Rusty leaf undersides? Gray/brown bumps on 1-year twigs? Note which — they separate virus/mite, rust, and scale.

Cut a dry fig open (1 min)

Hollow, tan, chaffy inside that never turned jammy red/amber? That pattern + a leaf photo is what identifies drought/mite vs. unpollinated variety.

📸 A photo of the fig’s canopy, one leaf close-up, and one cut fig — plus a photo of the apricot’s interior — would sharpen this plan from “ranked causes” to a firm diagnosis.

The fig rescue plan

Now (Nov): mulch ring — 2 in compost + 4 in wood chips over a 6–8 ft circle, 6 in clear of trunk.
Feb: horticultural oil just before bud swell if scale/mites were seen.
May–Sep: deep soak at the drip line — soaker hose / slow trickle 3–4 hrs, every 10–14 days, wetting 18–24 in deep. Non-negotiable during the Aug–Sep fruit swell.
Feed: essentially nothing — 1 in compost top-dress in March is enough. No nitrogen.
Prune lightly in late winter (dead/crossing wood, runaway shoots). Remember: breba crop grows on last year’s wood, main crop on this year’s — heavy winter pruning removes the June brebas.
Oct: strip off hard green figs that will never ripen so the tree banks energy for next year.

🌳 Tree-by-tree quick cards

🍋

Lemon

Feed Feb · May · JulFrost <29°F

Variety: Meyer lemon — confirmed by photo Nov 2, 2026. Planted by the previous owner; fruit comes in seasonal flushes — green part of the year, yellow-orange when ripe (that green-to-yellow pattern is normal ripening: all lemons start green and color up with cool nights). The cut-fruit photo settled the ID: thin rind, deep yellow-orange juicy flesh, round fruit, almost no seeds — that’s Meyer, the lemon × mandarin hybrid. A Eureka/Lisbon would show thick white pith and pale-yellow flesh. So the Meyer rules on this page apply: slightly less nitrogen than a true lemon, and ripe fruit holds on the tree for months — pick as needed.
What the Nov 2 photos also showed: (1) The sooty mold is heavy — it coats the fruit and most older leaves, which means a solid population of honeydew producers (scale most likely) is feeding it; the ant barrier + Nov 24 oil plan below is the right sequence, don’t skip the undersides check. (2) The canopy interior is dense and tangled with a lot of dead twiggy wood — do the cleanup at the normal lemon prune time, late March: dead wood out, a few crossing branches, open the center a little for light and air (a darker, stiller canopy is scale habitat). (3) Suckers are sprouting at the trunk base — rub/pull them off whenever you see them; growth from below the graft is rootstock and steals vigor. (4) Grass grows right up to the trunk — give this tree the same mulch ring treatment as the fig when you do it (6 in clear of the trunk).
Feed: heavy feeder — ~1.5 lb actual N/yr in 3 doses (late Feb, May, mid-Jul = last feed; trim toward ~1–1.25 lb if the tree proves to be a Meyer). Citrus fertilizer at the drip line, watered in. Yellow veins on new leaves → chelated iron/zinc/manganese in spring.
Water: deep soak every 10–14 days in summer; keep soil evenly moist in bloom (swings drop fruitlets).
Prune: light only, late Mar after frost risk — dead wood, suckers, crossing branches. Never Sep–Jan.
Frost: on a <29°F forecast, water that afternoon and drape frost cloth; pick ripe fruit first.
Watch: leafminer on new flush, scale/sooty mold. Harvest ripe fruit year-round — it stores best on the tree.

🟠

Persimmon (Fuyu)

Harvest mid-OctLight feeder

Status (Nov 1, 2026): the healthiest tree in the yard — gives roughly 100 lb of fruit a year. Its one issue is size: it has grown very big. Care below is mostly about keeping it, not fixing it.
Photo check (Nov 2, 2026): the tree stands in the back corner at roughly 16–18 ft, with one tall central leader and a wide canopy that overhangs both fences. The orange-red color at the top is normal persimmon fall color. Most of the crop is already in (a few stragglers + drops on the lawn — pick drops up so they don’t draw wasps/rats). Unlike the plum, nothing up top is tangled in wires: a single service drop passes above and to the side, so the leader reduction below is DIY pole-pruner work — just watch your distance from that drop. The 14 ft pole pruner (~15–17 ft reach) covers the top of this tree.
Feed: one light dose in March only (~3–5 lb balanced 10-10-10 at drip line). Too much N = June fruit drop.
Prune: late Jan — crossing/dead wood, tip back long vigorous shoots. Fuyu fruits on new shoots from last year’s wood. Size plan for a too-big tree: bring the top down gradually over 2–3 winters with reduction cuts (cut a tall leader back to a strong outward lateral at least ⅓ its thickness) — never a flat top in one year, which just triggers a thicket of upright regrowth. Persimmon tolerates this well, and with ~100 lb of production there is crop to spare. Target a height where most fruit picks from the ground or a short ladder.
Fruit load: persimmon wood is brittle — prop or tie up heavily laden limbs in Sep–Oct before they snap under the crop.
Water: deep soak every ~2 weeks May–Sep.
June drop is normal — the tree self-thins. If limbs still bend, thin to ~1 fruit per 6 in.
Protect: bag the best fruit in organza bags mid-Sep — squirrels, rats and jays take a bite of every ripening Fuyu. Harvest with clippers, calyx attached, at deep orange.

🍑

Nectarine

Leaf curl — spray!Thin to 6 in

Photo check (Nov 2, 2026): the nectarine stands right beside the lemon at roughly 13–15 ft — but wider than it is tall, arching over the fence, with a congested thicket of competing uprights where the open center should be, and its canopy merging into the lemon’s. That settles the tool question for this tree: the 14 ft pole pruner (15–17 ft reach) covers all of it from the ground, no ladder, no wires involved. Winter prune specifics for this tree: take out the competing central uprights to re-open the vase over 1–2 winters, thin the crossings, and cut back the branches invading the lemon’s space (the lemon needs the airflow for its whitefly/sooty-mold fight too). A few puckered leaves are still visible in the photos, consistent with the leaf-curl report; by November the worst curled leaves have long dropped, so the photos can’t grade the infection — next spring’s new growth is the real report card, which is why the copper pair below matters.
Peach leaf curl is THE job: fixed copper is prevention only, never a cure. Spray after leaf fall (late Nov), optionally midwinter in a wet year, and most importantly just before bud swell (late Jan–early Feb), with ~1% horticultural oil. Add dormant oil for scale/aphids.
Leaves already curled? (reported Nov 1, 2026) That is the fungus Taphrina deformans: leaves thicken, pucker and twist, often with a red-purple blush in spring. No spray can fix leaves that are already curled — infection happened back at bud swell, and the season's curled leaves are a done deal; they drop and the tree pushes a second, healthy flush. What actually helps: rake up and trash every fallen leaf (do not compost), don't overhead-water the canopy, keep the tree vigorous (water in dry spells, thin fruit hard if it defoliated), and hit the two preventive copper sprays above — leaf fall now, and pre-bud-swell in late Jan–early Feb. That pair is what makes next spring's leaves come out clean. Different look, different cause: tight leaf rolls with insects inside are aphids, and plain edge-curl in a heat wave is water stress — neither is leaf curl disease.
Prune: winter, on a dry week — open-center vase shape.
Thin: mid/late Apr, marble-size, to ~6 in apart. Prop heavy limbs in June.
Feed: part of the stone-fruit ration (~1–1.5 lb actual N/yr split Mar + May; halve it if roots share fertilized lawn).
Water: deep soak every 10–14 days May–harvest (Jul–Aug). Watch for brown rot — remove rotted fruit fast.

🟣

Plum

Thin to 4 inAphids in spring

What the Nov 2 photos showed: this plum was trained on a trellis against the house wall — and has escaped it. The top is now free-growing to roughly 18–20 ft, above the roofline and into the zone of the overhead service lines. The red/bronze leaf color in the photos is normal November senescence (leaves are about to drop), not disease. January plan: light thinning as below, plus reduction cuts on the upright whips to start bringing the top down over 2–3 winters and re-tie what can be saved to the trellis. ⚠️ Safety: do NOT pole-prune anywhere near the overhead lines — treat them as live. The top section by the wires is an arborist / utility-clearance job (or kept cut well back below the lines from the ground side only where there is clear distance); the lower two-thirds is DIY pole-pruner territory.
Prune: January, light thinning — plums fruit on long-lived spurs, so don’t shear them off. Keep the center open; control upright vigor.
Spray: dormant copper + oil after leaf fall, copper again before bud swell (shothole).
Thin: April, to ~4 in apart — plums over-set badly.
Feed/water: same ration and deep-soak rhythm as nectarine.
Watch: leaf-curl plum aphids on spring leaves — blast with water or insecticidal soap early. Harvest Jul–Aug.

Fig

See rescue plan ↑

Photo check (Nov 2, 2026): a small single-trunk tree (~10–12 ft) in the border bed, whitewashed trunk (paint worn — refresh before next summer with 50/50 white interior latex + water, especially the southwest side). Most leaves are down for the season — normal for a fig in November — but the leaves still hanging tell a story: pale, mottled, mosaic-patterned foliage with brown spotting, on thin twiggy growth. That pattern is consistent with fig mosaic disease (a virus spread by the fig bud mite) — very common in older backyard figs and made visibly worse by exactly the drought stress this tree lives with — with fig rust likely adding the brown spots. Mosaic can’t be cured and doesn’t usually kill the tree; managed well (water, below), trees like this still crop. Additions to the rescue plan: (1) the same dormant horticultural oil in the late-Nov spray round also targets overwintering bud mites — coat the buds/twigs well; (2) rake every fallen fig leaf into the trash/green waste (rust overwinters in them — the gardener brief applies here too); (3) at the late-winter prune, cut old stub ends back to clean collars (several are visible), and disinfect blades after this tree before using them elsewhere; (4) never take cuttings from this tree to start another fig — mosaic travels with them. The deep-soak + mulch-ring rescue stays the main lever: a less thirsty fig shows far milder mosaic symptoms.
Crops: breba in late June (on last year’s wood), main crop mid-Aug–Sep (on this year’s wood).
Water: deep soak every 10–14 days in summer — the single biggest lever on fruit size/juiciness.
Feed: none beyond a March compost top-dress.
Prune: late winter, light. Pick: only fully soft, drooping fruit — never early.

🧡

Apricot

Prune Jul–Aug ONLYNo nitrogen

Prune: late July–mid Aug, thinning cuts, open skylights, renew spurs in the sun. Never in winter/wet weather (Eutypa).
Spray: copper after leaf fall (shothole) + at red-bud in early Feb (brown rot). Never after blossoms open.
Feed: zero nitrogen — compost + mulch only, and keep lawn food 15–20 ft away.
Water: deep soak every 2–3 weeks after harvest too — next spring’s flower buds form in Aug–Sep.
Harvest: mid-June–early July. Feb bloom check: thousands of blossoms vs. scattered few = the chill test.

🍋 Lemon alert — black on the leaves AND the fruit

🪰 Honeydew source IDENTIFIED Nov 2, 2026: woolly whitefly

The leaf-underside photo settled who is feeding the mold: the undersides carry white, woolly, waxy patches spread across the leaf blade — the signature of woolly whitefly, a classic Bay Area citrus pest. Its nymphs sit on the undersides pumping out honeydew (plus those waxy filaments), and the sooty mold grows on the honeydew. Shake a branch: a puff of tiny white moths confirms it. Why it matters for the plan: (1) the Nov 24 horticultural oil is still the right fix — oil smothers the nymphs — but coverage of the undersides is now the whole game, since that’s where they live; (2) a hard hose blast a day or two before the oil physically knocks colonies off; (3) the ant barrier matters double — ants farm and protect whitefly exactly like scale; (4) pyrethrin (Captain Jack’s) is doubly wrong here — it barely touches the waxy nymphs but kills the tiny parasitoid wasps that are woolly whitefly’s main control, which is likely part of why this flared; (5) a handful of the very worst curled, colony-covered leaves can be pinched off and trashed anytime — that’s sanitation, not pruning. Scale may also be present in small numbers; the oil covers both.

✅ Diagnosis CONFIRMED Nov 1, 2026: sooty mold

Confirmed at home — it is sooty mold (the wipe-off kind), and the tree was sprayed with Captain Jack’s Orchard Spray (sulfur + pyrethrin) around Sun Oct 25, 2026. The 21-day label minimum for oil passes Sun Nov 15; the safe 30-day date is Tue Nov 24, 2026 — that’s oil spray day (a reminder is set for that morning). Status and next steps: (1) the spray knocks down exposed aphids/whiteflies but does not reliably kill scale, and its pyrethrin also kills scale’s natural enemies — so don’t keep re-spraying it; (2) horticultural oil is the real scale fix, but it must wait at least 21 days after the sulfur spray (label interval; ~30 days is the conservative count) or the oil + sulfur residue burns leaves and rind; (3) until the oil date: ant barrier on the trunk, prune ant bridges, hose-blast the canopy a day or two after the spray, wash fruit before use, and use insecticidal soap only if live aphids/whitefly flare up; (4) once the interval passes, do the 1–1.5% oil spray below, targeting twigs and leaf undersides where scale sit.

First: it is probably not “black spot disease”

In Santa Clara in November, black coating on lemon leaves and lemons is sooty mold in roughly 9 cases out of 10 (UC Santa Clara flags it as a fall citrus issue here). Sooty mold is a harmless surface fungus that grows on honeydew — the sticky sugar that scale, aphids, mealybugs and whiteflies excrete. It does not infect the tree, and the fruit stays edible. The true citrus black spot disease is a quarantined warm-humid-climate pathogen, not established in Bay Area backyards — and CDFA says it must never be diagnosed from looks alone. So don’t spray fungicide yet: run the test.

🔍 The 2-minute test — wet soapy paper towel + a fingernail

Wipe test (30 sec): rub a black leaf and a black lemon firmly. Black smears off like charcoal dust, clean green/yellow underneath → sooty mold, confirmed.
Fingernail flick (30 sec): tiny 1–3 mm dark round spots that pop off like a waxy shell → those “spots” are scale insects themselves (black/brown soft scale, red scale) — the honeydew source, often alongside the mold. A spot that is sunken into the rind and won’t scrape off → a true lesion: Septoria spot (sunken tan/black pits) or bacterial blast. Raised and rough like sandpaper → melanose.
Underside + sticky check (30 sec): leaves feel sticky (fresh honeydew)? Flip leaves: white cottony puffs (whitefly/mealybug) or flat oval bumps on twigs (soft scale)?
Ant highway (30 sec): a line of ants up the trunk confirms honeydew insects — ants guard scale from ladybugs and parasitic wasps.

📸 One close-up of a spotted leaf and one of a spotted lemon, before and after the wipe, settles this for certain.

If it’s sooty mold + scale (the likely case) — November fix

Ants first: sticky barrier (e.g. Tanglefoot) on a tape band around the trunk — never on bare bark — plus ant bait at the base, and prune any branch touching a fence/wall/ground (ant bridges). How to build the band (~10 min): pick a smooth spot ~12–18 in above ground, below the lowest branch (wrap every trunk stem on a multi-stem tree); wipe off loose bark and let the trunk dry; wrap a 3–4 in wide band of painter’s/masking tape snugly all the way around with no gaps underneath — ants crawl under loose tape — stuffing any deep bark cracks with a bit of cotton first; wearing disposable gloves, spread Tanglefoot ~⅛ in thick across the full width of the tape with an old spatula (it is extremely sticky — keep it off skin and clothes, and never spread it on the bark itself, where it can burn and girdle). If a support stake touches the tree, band the stake too. Refresh it when dust and dead ants carpet it into a bridge (every ~4–8 weeks), and peel the tape off after the season rather than leaving it on year-round.
Blast & wash: strong hose jet in the morning to knock off honeydew, whiteflies and loosened mold.
Horticultural oil: 1–1.5% (~2½–3 Tbsp/gal) in the pump sprayer, wetting leaf tops, undersides and twigs where scale hide; repeat in 2–3 weeks if live scale remain. Never spray if it will exceed 85°F or drop below 40°F within 24 hrs, never on a wilted/drought-stressed tree, and spray early morning, not into open blossoms at bee hours.
Fruit: sooty lemons are safe to eat/juice — scrub the rind in warm soapy water first.

⚠️ Leave the Captain Jack’s Orchard Spray on the shelf for this. Its sulfur won’t remove mold or kill scale, and its pyrethrin kills the ladybugs and parasitic wasps that eat scale — it can make the outbreak worse. And never use horticultural oil within 30 days of a sulfur spray (before or after) — the combination burns citrus leaves and rind. If the Captain Jack’s was sprayed in October, count 30 days from that date before any oil; use insecticidal soap in between.

If the spots do NOT wipe or flick off — Septoria / bacterial blast plan

These are the #2 true diseases of NorCal lemons in cool, wet Nov–Jan weather, and UC IPM’s prevention is the same for both: one fixed-copper spray in Oct–Dec, just before or after the first rain — i.e. right now (Liqui-Cop / Bonide Copper — a plain copper product, not the sulfur spray).
Copper is preventive only — it won’t erase spots already on this year’s lemons. Harvest heavily spotted ripe fruit now.
Damage is skin-deep and cosmetic: flesh and juice are still safe (wash well; just don’t use pitted peel for zest). Prune out dead twigs in spring — dead wood also feeds melanose.
If sunken spots ever show gray/tan centers with a brick-red rim on the sun side of ripening fruit, don’t self-diagnose — send photos to the UC Master Gardener clinic / county ag commissioner, because that pattern is the one that resembles the quarantined disease.

🌹 Roses & the other flower plants

Roses — the year in one card

The big prune is January (Jan 1–20, around MLK weekend): hybrid teas/grandifloras down by ⅓–½ to ~24–36 in, keeping 4–6 healthy canes in an open vase, cuts ¼ in above an outward-facing bud. Floribundas/shrub roses lighter — ¼–⅓ off, thin the middle. Climbers: keep the main horizontal canes, shorten side shoots to 3–5 buds. Strip every remaining leaf by hand — Santa Clara roses never fully drop them, and old leaves carry black spot, rust and mites through winter. Rake up everything underneath. Then dormant copper + horticultural oil.
Feed Mar–mid-Sep only: every ~6 weeks from when new growth is 4–6 in (mid-Mar), after each bloom flush (May, late Jun, mid-Aug). Roughly 1 cup organic granular rose food per mature bush, scratched in at the drip line and watered in, + ½ cup alfalfa meal in Mar and Jun. Hard stop Sep 15 — late food = frost-tender growth.
Water at the base, never overhead: drip/soaker, deep soak 1–2×/week in summer (~4–5 gal per mature bush, 12–18 in deep in clay). Lawn sprinklers wetting rose foliage = a black spot and rust factory — redirect or cap heads that hit the beds, and put roses on drip.
Deadhead Apr–Oct (until the November stop): cut spent blooms back to the first outward 5-leaflet leaf. That’s what keeps repeat bloomers cycling.
If the gardener prunes the roses: light tidying and deadheading in season is fine to delegate. The January structural prune + full leaf strip stays owner-directed (or explicitly briefed), because that one prune sets the year — and ask him to wipe blades with alcohol between bushes: shared tools carried yard-to-yard are a classic way black spot and rust travel.
Mulch: 3 in of chips/composted bark year-round, 3–4 in clear of the crown/graft.
Sun: roses need 6+ hours of direct sun. The apricot’s July–Aug summer thinning doubles as a rose health boost for any bed it shades.
⚠️ The no-nitrogen overlap: roses planted within 15–20 ft of the apricot or fig share soil with those roots — feeding those roses feeds the apricot back into fruitless leaf growth. For roses in that zone: compost mulch + low-N bone meal/kelp only, no rose food.
Adding/replacing a rose? Bare-root season is Jan–early Feb: soak roots 12–24 hrs, wide hole in clay mixed ~50% native soil + 50% compost (never pure potting mix — it makes a soggy clay “bathtub”), bud union 1–2 in above soil level.

Rose problem	When it peaks here	Prevention first	Least-toxic control
Black spot — fringed black circles, yellowing leaves drop	Feb–May, Oct–Nov (wet, 60–75°F)	Strip leaves at Jan prune, rake fallen leaves, no sprinkler splash	Dormant copper + oil in Jan after pruning
Powdery mildew — white powder on young shoots/buds	Apr–Jun, Sep–Oct (warm days, cool dewy nights)	Open airflow, avoid high-N food, water base in the morning	Potassium bicarbonate, or 1% horticultural oil/neem (never above 85°F)
Rust — orange pustules under leaves	Apr–Jun, Sep–Oct (cool moist mornings)	Remove infected lower leaves at once, trash them; morning watering only	Sulfur or neem/oil on leaf undersides, cool morning
Aphids — clusters on tender buds	Mar–May (spring flush)	Don’t over-fertilize; let ladybugs/lacewings work	Sharp hose jet (knocks most off); insecticidal soap if severe. UC Santa Clara’s #1 rose pest — and the easiest.
Thrips — brown crispy petal edges, buds won’t open	May–Aug (worst on light-colored blooms)	Deadhead promptly and trash spent blooms	Spinosad on tight closed buds only, in the evening, away from bees
Spider mites — bronzed stippled leaves, fine webbing	Jul–Sep (hot, dusty spells)	Keep roots watered; hose-wash leaf undersides weekly in heat waves	Insecticidal soap / horticultural oil on leaf undersides

Roses month-by-month (quick line)

Nov: stop deadheading + feeding, let hips form, sanitation rake-up. No pruning yet.
Dec: rest. Plan any bare-root orders.
Jan: THE prune + leaf strip + dormant copper/oil + bare-root planting. Mulch after.
Feb: finish pruning/planting by mid-Feb. First light feed as growth starts, watered in.
Mar: main feed when growth is 2–6 in. Aphid watch begins.
Apr: first buds; aphids, rust, mildew watch. Start deadheading after first blooms fade.
May: peak bloom. Deadhead constantly. Feed after the first flush. Thrips watch.
Jun: feed again (+ alfalfa). Deep water 1–2×/week as heat builds.
Jul–Aug: water is the job; mite watch in heat. Last feed mid-Aug.
Sep: light tidy of leggy growth; fall bloom improves as nights cool. Feeding stops Sep 15. Rust watch returns.
Oct: enjoy the last flush; clean up fallen leaves promptly (disease for next year starts here).

📸 One photo of 2–3 typical bushes (shape + the base/graft) would tell us if yours are hybrid teas, floribundas, shrub roses or climbers — the January prune differs by type — and whether any rootstock suckers have taken over an older bush.

🌸 The other flower plants — shared rules

Almost everything above generalizes: water at the base in the morning, mulch 2–3 in, feed only in the growing season, deadhead spent flowers to keep blooms coming, and clean up diseased leaves into the trash, never the compost.
Perennials: cut back dead top growth in late fall/winter, divide overgrown clumps in fall or early spring, top-dress with compost in March.
Spring bulbs (daffodils, tulips, ranunculus): plant Oct–Dec for spring bloom — fall is the window, and it’s open right now.
Seasonal color: cool-season annuals (pansies, violas, snapdragons) go in Oct–Nov here; warm-season color waits until after last frost (~mid-Mar).
Keep flower-bed fertilizer out of the apricot/fig root zone, same as the roses — beds near those trees get compost, not high-N food.

🌱 The lawn

Mow high: 3 in most of the year, 3.5–4 in in summer heat. Taller grass shades out crabgrass and saves water. Leave clippings on the lawn. Mow sparingly in winter; stay off soggy clay (compaction).
Water: deep, early morning (5–7 AM), ~2×/week in summer — not daily sprinkles. 1×/week or off once rains start. Remember the trees nearby want the opposite rhythm — don’t let the lawn schedule be the trees’ schedule.
Best month is September: core-aerate the clay, top-dress ¼ in compost, overseed with tall fescue + starter fertilizer (late Sep).
Feed: spring (Mar) + early-Nov winterizer. Never fertilize in Jul–Aug heat — and keep spring lawn food 15–20 ft away from the apricot trunk.
Spring: a second aeration in Mar if compacted; spot-pull winter weeds (oxalis, annual bluegrass) before they seed in Feb.

💧 How this yard is actually watered — confirmed Nov 1, 2026

All the trees sit in or next to the lawn, so there is no way to keep sprinkler water off them — and no drip anywhere. The lawn sprinklers run twice a week, 10–15 minutes, April–November; December–March the trees run on rain alone. A 10–15 minute sprinkler run puts down roughly 0.15–0.25 in of water — the top 2–4 in of soil. That single fact explains both problem trees: the fig’s deep roots stay thirsty all summer (small, dry figs), while the apricot sips constantly at the surface and over-grows. The lawn schedule stays as it is; the trees get three add-ons that need no irrigation work:

Soaker-hose ring at the drip line (fig and lemon first). One cheap soaker hose on a garden hose, ringed at the drip line, run at a slow trickle for 3–4 hours every 10–14 days, May–Sep — that’s the deep soak the sprinklers can’t give, and it’s what fills figs out. Stone fruit gets the same soak every 10–14 days from May to harvest if rain is absent; persimmon likewise in a dry summer.
Apricot gets NO extra water. It is already the best-watered tree in the yard for the wrong reasons; added deep water in clay risks crown/root rot and more vegetative growth. Its fix stays fertilizer exclusion + the July–August thinning prune.
Cycle-and-soak the lawn runs. Same total minutes, split into 2 cycles with a 30–60 min gap (e.g. 2 × 7 min instead of 1 × 14 min). Clay absorbs far more that way, runoff drops, and both lawn and tree roots get water a couple of inches deeper for free.
Mulch rings (fig first, per the fig plan) cut the lawn’s competition and evaporation right where the feeder roots are.
Winter dry spells: if Dec–Feb brings under ~½ in of rain across any 3 weeks, give the lemon one hose deep-soak — it’s evergreen and keeps drinking all winter while the deciduous trees sleep.

👨‍🌾 Working with the weekly gardener

The gardener comes weekly (sometimes a week is skipped) and covers mowing, blowing and leaf cleanup, with occasional light pruning of the rose bushes — he rarely touches the trees. So everything tree-shaped on this page is owner work (or an arborist’s, for a big job); the gardener brief is about not undoing it:

Leaves under the nectarine and the roses: rake and bag into green waste — don’t blow them into the beds or under other trees. Fallen nectarine leaves carry leaf-curl fungus and fallen rose leaves carry black spot; his weekly cleanup is genuinely good disease control, but only if the leaves actually leave.
Fallen and mummified fruit: pick it up and bin it (especially under the apricot — that’s brown-rot control for next year).
No string-trimmer or mower contact with trunks. Trunk wounds (“mower blight”) are a top backyard-tree killer. The mulch rings on this page double as a no-trim buffer — keep them intact, 6 in clear of the trunk.
Mow at 3 in (3.5–4 in in summer heat), clippings left on the lawn.
Never prune the apricot except in the late Jul–mid Aug window, and only if asked — wet-season cuts are how Eutypa dieback gets in. And no topping of any tree, ever; height comes down by reduction cuts in the dormant plan, owner-directed.
Rose pruning he does: in-season deadheading/tidying is fine; the January structural prune is owner-directed, and blades get an alcohol wipe between bushes (see the rose section).
