That's real food security. But fruit trees are a long game — you're making decisions now that determine production 5, 10, 50 years from now. This skill covers everything from site selection and variety choice to pruning, pest management, and the faster-payoff option of berry bushes for people who can't wait five years for their first apple. The critical insight most people miss: rootstock selection and formative pruning in the first three years determine 80% of your tree's lifetime productivity. ```agent-adaptation # Localization note — fruit tree management is deeply climate-specific. # Agent must follow these rules when working with non-US users: - USDA Plant Hardiness Zones are US-specific. International equivalents: UK: RHS Hardiness Ratings (H1-H7) Europe: EEA plant hardiness maps Australia: Sunset Climate Zones or ANBG zones Canada: Canadian Plant Hardiness Zones (similar to USDA but separate system) - Chill hour requirements are universal but sources differ by country. Agent MUST look up the user's specific zone and chill hours. - Variety recommendations are regional. Local extension service equivalents: UK: Royal Horticultural Society (rhs.org.uk) Australia: State Department of Primary Industries Canada: Provincial agriculture ministry EU: National agricultural advisory services - Pest and disease pressures vary by region. The spray schedules listed assume temperate North American conditions. Agent should reference local integrated pest management (IPM) guides. - Citrus zones referenced (USDA 9-11) should be converted to local equivalent zones. Container growing is viable anywhere with indoor winter storage. - Berry bush recommendations (blueberry soil pH, raspberry management) are broadly applicable but variety selection must be localized. ``` ## Sources & Verification - **USDA Plant Hardiness Zone Map** -- essential for variety selection. [planthardiness.ars.usda.gov](https://planthardiness.ars.usda.gov/) - **Michael Phillips, "The Holistic Orchard"** -- comprehensive organic orchard management - **Fedco Trees catalog** -- variety descriptions are excellent practical references for cold-climate growers - **State cooperative extension fruit tree guides** -- free, research-backed, regionally specific (search "[your state] extension fruit tree guide") - **University IPM (Integrated Pest Management) programs** -- evidence-based pest management by region - **Lee Reich, "Grow Fruit Naturally"** -- organic fruit growing without synthetic inputs - **USDA Web Soil Survey** -- free soil type maps for any parcel. [websoilsurvey.nrcs.usda.gov](https://websoilsurvey.nrcs.usda.gov/) ## When to Use - User wants to plant fruit trees and doesn't know where to start - Someone just bought property and wants to maximize food production - User has existing fruit trees that aren't producing well or look unhealthy - Someone wants fruit but doesn't want to wait years — berry bushes - User needs help choosing varieties for their specific climate zone - Someone is planning a small home orchard layout ## Instructions ### Step 1: Assess the site **Agent action**: Ask the user for their location (or zip code for zone lookup), property details, and goals. Check the non-negotiable requirements before recommending anything. ``` SITE ASSESSMENT CHECKLIST: Sunlight (non-negotiable): [ ] 6+ hours of direct sun daily — most fruit requires full sun [ ] 8+ hours is ideal for stone fruit and maximum production [ ] Partial shade (4-6 hours) limits you to: sour cherry, gooseberry, currants, some raspberry varieties Drainage: [ ] Dig a 12" deep hole, fill with water, time the drain -> Drains in 1-4 hours: excellent -> Drains in 4-6 hours: acceptable for most fruit trees -> Drains in 6-12 hours: raised beds for berries only -> Standing water after 12 hours: not suitable for fruit trees [ ] Fruit trees die in wet feet — this is the #1 site killer Air circulation: [ ] Gentle air movement reduces fungal disease [ ] Avoid frost pockets (low spots where cold air settles) [ ] Hilltops and slopes are better than valleys for fruit Soil: [ ] Get a soil test ($15-30 through your county extension office) [ ] Most fruit trees prefer pH 6.0-7.0 [ ] Blueberries need pH 4.5-5.5 (acidic — plan ahead) [ ] Soil test tells you what amendments to add BEFORE planting Space: [ ] Dwarf trees: 8-10 ft apart [ ] Semi-dwarf trees: 12-15 ft apart [ ] Standard trees: 20-25 ft apart [ ] Berry bushes: 3-6 ft apart depending on type ``` ### Step 2: Choose the right varieties **Agent action**: Look up the user's USDA zone and chill hours. Recommend varieties that actually work for their climate. This is where most beginners go wrong. ``` UNDERSTANDING CHILL HOURS: Chill hours = hours below 45F during winter dormancy. If your area doesn't get enough chill hours for a variety, the tree will never produce fruit reliably. Period. Lookup: Search "[your city] chill hours" or check your state extension office website. High chill (800-1000+ hours): Northern US, upper Midwest Medium chill (400-700 hours): Mid-Atlantic, Pacific Northwest Low chill (100-400 hours): Deep South, coastal California Minimal chill (<100 hours): Southern Florida, Hawaii, tropics FRUIT TYPE GUIDE: APPLES (most forgiving for beginners): - Need 2 different varieties for cross-pollination - Hundreds of varieties — match chill hours to your zone - Produce in 2-3 years (dwarf) to 5-7 years (standard) - Disease-resistant varieties save you spray work: Liberty, Enterprise, Freedom, GoldRush, Pristine PEARS: - Similar requirements to apples, less pest pressure - European pears (Bartlett, Bosc) — pick unripe, ripen off tree - Asian pears — eat crisp off the tree, less cold-hardy - Fire blight is the main disease risk — choose resistant varieties STONE FRUIT (peach, plum, cherry, apricot): - Shorter-lived trees (15-25 years vs 50+ for apple) - More disease and pest pressure - Incredible production when they work - Peaches: many are self-fertile (one tree is enough) - Sweet cherries: need a pollinator, large trees - Sour cherries: self-fertile, smaller, easier - Plums: European (self-fertile) vs Japanese (need pollinator) CITRUS (zones 9-11 only, or container anywhere): - Meyer lemon is the easiest starter citrus - Container citrus works in any climate with indoor winter storage - Need winter temps above 28F (most varieties) ``` ### Step 3: Select rootstock **Agent action**: Explain rootstock and its impact. This decision affects the next 50 years. ``` ROOTSTOCK DETERMINES: -> Tree size at maturity -> Years until first fruit -> Lifespan and vigor -> Disease resistance -> Anchoring (some need permanent staking) ROOTSTOCK OPTIONS: DWARF (8-10 ft mature height): - First fruit: 2-3 years - Full production: 4-5 years - Requires permanent staking (weak root system) - Easier to prune, spray, and harvest - Best for: small yards, intensive management - Common apple dwarf rootstocks: M9, M26, Bud 9 SEMI-DWARF (12-15 ft mature height): - First fruit: 3-4 years - Full production: 5-6 years - May need staking first 2-3 years only - Best balance of size, production, and manageability - RECOMMENDED FOR MOST HOME GROWERS - Common: M7, MM106, MM111 STANDARD (20-30 ft mature height): - First fruit: 5-7 years - Full production: 8-10 years - No staking needed, deep root system - Massive production (10-20 bushels per tree) - Requires ladder for pruning and harvest - Best for: large properties, low-maintenance orchards - Common: seedling rootstock ``` ### Step 4: Plant correctly **Agent action**: Walk through planting technique. Mistakes at planting create problems for decades. ``` PLANTING GUIDE: TIMING: - Bare root trees: plant during dormancy (late winter/early spring) Cheapest option, widest variety selection - Potted trees: plant anytime ground isn't frozen More expensive, limited selection, more forgiving timing PLANTING STEPS: 1. Dig the hole: - Width: 2x the root ball or root spread - Depth: SAME as root ball — do NOT plant too deep - The graft union (bulge where rootstock meets variety) must be 2-3 inches ABOVE soil line - Planting too deep causes rootstock to root above the graft, defeating the purpose of your rootstock choice 2. Prepare roots: - Bare root: soak in water for 1-2 hours before planting - Trim any broken or circling roots - Spread roots outward — NEVER let them circle - Circling roots eventually girdle and kill the tree 3. Backfill: - Use the same soil you dug out (no amendments in the hole) - Amendments in the hole create a "bathtub effect" — roots won't grow out into native soil - Tamp gently to remove air pockets - Water thoroughly — 5-10 gallons to settle soil 4. Mulch: - 3-4 inches of wood chips in a donut shape - Keep mulch 6 inches away from the trunk (prevents rot) - Extend mulch to the drip line 5. Staking (dwarf rootstock only): - One sturdy stake, 18" from trunk - Tie loosely — allow some movement for trunk strength - Leave stakes for 2-3 years (permanent for M9) ``` ### Step 5: Formative pruning (years 1-3) **Agent action**: Explain the two main pruning forms and the counterintuitive first-year rule. ``` THE FIRST 3 YEARS DETERMINE EVERYTHING: YEAR 1 — COUNTERINTUITIVE BUT CRITICAL: Remove all fruit in year 1. Yes, all of it. Let the tree build its root system and framework. Picking off flowers/fruitlets now means dramatically better production for the next 20-50 years. PRUNING FORMS: Central Leader (for apples, pears): - One dominant vertical trunk - Scaffold branches spiral around it at 6-8" vertical spacing - Creates a Christmas tree shape - Strong structure, good light penetration Open Center / Vase (for stone fruit): - Remove the central leader at planting - Select 3-4 scaffold branches growing outward - Creates an open bowl shape - Better for stone fruit — more light, air circulation YEAR 1 PRUNING: Central leader: Head the tree at 30-36" at planting. Select the strongest upright shoot as the leader. Remove competing leaders. Open center: Cut the trunk to 24-30" at planting. Select 3-4 well-spaced scaffold branches. Remove everything else. YEARS 2-3 PRUNING: - Continue shaping the framework - Remove crossing branches - Remove inward-growing branches - Remove water sprouts (vigorous vertical shoots) - Maintain open canopy for light and air - Head scaffold branches to encourage branching THE 3 D'S (every year, forever): Always remove Dead, Diseased, and Damaged wood first. Then address structure. ``` ### Step 6: Ongoing management **Agent action**: Cover annual care, thinning, and pest/disease management. ``` ANNUAL CARE CALENDAR: LATE WINTER (dormant): - Major pruning (while you can see the structure) - Apply dormant oil spray (smothers overwintering insects and eggs) - Order any new trees for spring planting SPRING (bud break through petal fall): - Fertilize lightly (compost ring around drip line, or balanced organic fertilizer — do NOT over-fertilize, excess nitrogen means lots of leaves, little fruit) - Neem oil spray at petal fall (when petals drop, NOT during bloom — spraying during bloom kills pollinators) - Monitor for fire blight on apples/pears (blackened, wilted shoots) EARLY SUMMER: - THIN FRUIT: Remove 50% of developing fruitlets -> Counterintuitive, but remaining fruit is larger, sweeter, and the tree stays healthier -> Apples: thin to one fruit per cluster, 6" apart on branch -> Stone fruit: thin to 4-6" between fruit - Continue spray program every 2-3 weeks if using organic sprays - Monitor for codling moth, apple maggot, plum curculio SUMMER: - Water deeply during dry spells (1-2" per week) - Monitor for pest and disease - Harvest as fruit ripens FALL: - Clean up fallen fruit (reduces pest overwintering) - Apply tree wrap to young trunks (prevents sunscald and rodent damage) - Final mulch application before winter - Do NOT prune in fall (wounds heal slowly, invites disease) COMMON DISEASES: - Apple scab: fungal, causes spots and cracking. Resistant varieties eliminate this problem entirely. - Fire blight: bacterial, kills branches fast. Prune 12" below visible infection, sterilize tools between cuts. - Brown rot: stone fruit nightmare. Remove mummified fruit, improve air circulation, fungicide if severe. - Cedar-apple rust: remove nearby cedar/juniper or plant resistant varieties. ``` ### Step 7: Berry bushes for faster results **Agent action**: If the user wants faster production or has limited space, present berry options as a complement or alternative to fruit trees. ``` BERRY BUSHES — FRUIT IN 1-3 YEARS: BLUEBERRIES: - Need ACID soil: pH 4.5-5.5 (amend with sulfur if needed) - Plant 2+ varieties for cross-pollination - Production: small harvest year 2-3, full production year 5-6 - Yield: 5-10 lbs per mature bush - Lifespan: 20-30 years - Need: full sun, consistent moisture, acidic mulch (pine needles) - Easiest varieties: Bluecrop, Duke, Patriot (highbush) RASPBERRIES: - Production: small harvest year 2, full production year 3 - Yield: 3-5 lbs per row-foot per year - Types: summer-bearing (one crop) vs everbearing (two crops) - They SPREAD AGGRESSIVELY — plant in a contained bed or be prepared to manage suckers constantly - Pruning: remove canes that fruited (they only fruit once on summer-bearing), keep new canes for next year - Easiest: Heritage (everbearing), Latham (summer-bearing) BLACKBERRIES: - Production: year 2, full production year 3 - Yield: 5-10 lbs per plant - Thornless varieties exist and produce well (Triple Crown, Chester) - Similar management to raspberries — contain the spread - More heat-tolerant than raspberries STRAWBERRIES: - Production: small harvest year 1, full production year 2 - Yield: ~1 lb per plant per year - Types: June-bearing (one big crop) vs everbearing (smaller continuous harvest) - Replace plants every 3-4 years (they decline) - Great for small spaces, raised beds, containers - Net them or the birds get everything CURRANTS AND GOOSEBERRIES: - Tolerate partial shade (4+ hours sun) - Production: year 2-3 - Yield: 5-10 lbs per bush - Very cold-hardy, low maintenance - Illegal to grow in some areas (white pine blister rust host) — check state regulations ``` ## If This Fails - **Tree isn't producing fruit after expected timeframe?** Check: chill hours met? Pollination partner present? Over-fertilizing with nitrogen? Pruning too aggressively (removing fruit wood)? Some varieties are biennial bearers (heavy crop one year, light the next). - **Tree looks sick?** Take photos of leaves, bark, and fruit to your county extension office or local nursery. They diagnose for free. Don't guess on treatments. - **Deer eating everything?** Individual tree cages (welded wire, 5 ft tall minimum) are the only reliable solution short of a full perimeter fence. Spray deterrents work temporarily at best. - **Overwhelmed by pest management?** Plant disease-resistant apple varieties (Liberty, Enterprise) and skip the spray schedule entirely. You'll get imperfect-looking fruit that tastes just as good. - **Wrong variety for your climate?** If a tree isn't thriving after 3 years, consider grafting a better variety onto the existing rootstock rather than starting over. Or accept the loss and replant correctly. ## Rules - Always look up the user's USDA zone and chill hours before recommending specific varieties - Never recommend planting without confirming adequate drainage and sunlight - Emphasize formative pruning in years 1-3 — this is when most beginners make permanent mistakes - If the user has existing sick trees, recommend extension office diagnosis before suggesting treatments - Adjust all timing for the user's hemisphere and climate - Always mention pollination requirements — a single apple tree won't produce ## Tips - Buy from local nurseries when possible. Their stock is selected for your climate, and their advice is specific to your area. Mail-order is fine for variety selection but local beats catalog every time. - Fruit tree tags at big box stores often list the wrong zone. Trust the variety name and look up the specs yourself. - The best time to plant a fruit tree was 10 years ago. The second best time is this dormant season. - Start with 2-3 trees maximum. Learn on those before expanding. A neglected orchard produces worse than no orchard. - Save your pruning cuts to use as scion wood. Once you learn to graft, you can multiply any variety for free. - Compost is the best fertilizer for fruit trees. A 2-inch layer around the drip line each spring is all most trees need. ## Agent State ```yaml state: site: usda_zone: null chill_hours: null sun_hours: null drainage_tested: false soil_test_done: false soil_ph: null space_available_sqft: null trees: planted: [] varieties: [] rootstocks: [] planting_dates: [] current_year_of_growth: {} pruning_form: {} berries: planted: [] varieties: [] planting_dates: [] management: last_pruning_date: null last_spray_date: null thinning_done_this_year: false pest_issues_current: [] disease_issues_current: [] harvest: total_yield_lbs: {} harvest_dates: [] follow_up: next_pruning_due: null next_spray_due: null seasonal_tasks_pending: [] ``` ## Automation Triggers ```yaml triggers: - name: dormant_pruning_reminder condition: "management.last_pruning_date IS NULL OR month_since(management.last_pruning_date) >= 11" schedule: "annually in late winter (February-March)" action: "Dormant season is here — time for major pruning.
