New to Fruit Trees?
A beginner's guide to growing fruit and using this app
🧙 Guide Wizards — Start Here
New to fruit growing? The fastest way to get set up is to let the wizards walk you through it. Each one asks a few simple questions and builds personalized recommendations.
🍎
What Does This App Do?
In short: what to spray, when, and how much
Spray Recommendations
Based on your fruit, stage, weather, and inventory — exact products + mix rates for your sprayer size.
Weather Integration
Real 7-day forecast; identifies the best spray windows and warns when rain is coming.
Product Inventory
Only recommends from what you own. Mix Checker warns on dangerous combinations.
Disease & Pest ID
Illustrated gallery to identify problems and get research-backed control advice.
Spray Log
History-driven scheduling. Warns when coverage lapses or sprays are overdue.
🌱
Beginner Terminology
The words you'll encounter throughout the app
Growth Stages
Predictable annual stages: dormant → green tip → tight cluster → bloom → petal fall → cover sprays through harvest. Different diseases and pests attack at different stages, so stage-right timing is everything.
Varieties
The specific name of your fruit tree — like dogs have breeds. Honeycrisp, Fuji, Gala. Each has different disease resistance, flavor, and harvest timing.
Rootstock
Nursery trees are two grafted together: the variety you eat on top, a different root system (rootstock) below. Rootstock controls tree size — dwarf (6-10 ft), semi-dwarf (12-18 ft), or standard (25+ ft). Fruit flavor is unchanged.
Cross-Pollination
Many trees need pollen from a DIFFERENT variety of the same fruit — they can't pollinate themselves. Others (like most peaches and figs) are self-fertile. The Pollination section tells you exactly what your fruit needs.
Fungicide vs Insecticide
Fungicides kill fungal diseases (scab, rot, mildew). Insecticides kill insects (moths, beetles, maggots). Different products, different jobs. Most trees need both — the Mix Checker tells you what's safe to combine.
Organic vs Conventional
Organic: copper, sulfur, neem, Spinosad — natural sources, approved for organic. Conventional: Captan, Immunox, Sevin — synthetic. Both work. Filter your inventory either way.
PHI (Pre-Harvest Interval)
Days between last spray and picking fruit. Varies by product AND fruit — Captan is 0 days on apples, Immunox is 14 days on stone fruits. Always check the PHI shown in each product's fruit-specific details.
FRAC / IRAC Groups
Chemical groupings by mode of action. Rotating across groups prevents resistance. You don't need to memorize them — the app handles it in its recommendations.
🚀
How to Get Started
About 5 minutes, start to finish
1
Set your location
Tap the 📍 location area at the top and search your zip code or city. This powers weather, USDA zone, and auto-detected growth stages.
2
Pick your fruits
Open ⚙️ My Orchard Setup → 🌳 My Fruit Types and tap tiles for each fruit you grow. Green dots show zone-fit. Tap 🎯 Help me choose for a 4-step wizard.
3
Check your products
Tap the 🧴 My Products bar and check off products you own. Don't own any yet? Start with two: a copper fungicide for dormant + Captan for growing season. Or use 🛒 Don't know what to buy? for a shopping wizard.
4
Follow the recommendations
Open 🎯 Spray Program. Tap the green 🎯 Start Spray Wizard — 4 simple steps: weather → pick day → spray plan → log. Or use the Mix Recommendation for quick reference.
5
Add your varieties
In 🍎 My Varieties: use 🌱 Guide Me for a 4-step wizard or + Add Variety for manual entry. Catalog of 800+ varieties with auto-fill for disease resistance, harvest, and rootstock.
That's it. The app does the rest — calculating rates, checking compatibility, tracking your schedule, and warning you when coverage lapses.
💡
Quick Tips for First-Time Growers
Hard-won lessons worth remembering
Start small.
Two or three trees is plenty to learn on. Don't plant 20 trees your first year.
Dormant spray is the most important spray of the year.
Copper + oil in late winter before buds open prevents more problems than all other sprays combined. Don't skip it.
Timing matters more than product.
A cheap fungicide at the right time beats an expensive one applied too late. The stage tracking helps you nail timing.
NEVER spray insecticides during bloom.
Bees are pollinating. Kill the bees and you get zero fruit. The app warns you about this.
You will lose some fruit.
Even commercial orchards lose 10-30% to disease and pests. Expect improvement each year, not perfection.
Read the label.
The label is the law — legal rate, fruits registered, PHI, safety. The app provides label links for every product.

About Orchard SprayWise
From one home grower to another
👋 Hi, I'm Tim.
I'm just a regular person who wanted to grow fruit trees. I planted my first trees with zero experience and quickly learned that growing beautiful, healthy fruit is a lot harder than sticking a tree in the ground and waiting.
My first years were full of failures — scabby apples, wormy peaches, trees lost to fire blight, fruit destroyed by brown rot overnight. Every time I searched for answers, the information was either too academic, too vague, or buried across dozens of university extension sites that assumed you already knew the terminology.
I couldn't find a single tool that told me what to spray, when to spray it, how much to mix, and what NOT to mix together — all in one place, tailored to what I actually had on hand. So I built one.
This app is everything I wish I'd had when I started. Whether you're planting your first apple tree in the backyard or managing a small orchard, I hope this saves you the years of trial and error it took me to figure it all out.
Built by a home grower who learned the hard way — so you don't have to.
— Tim Eagle Monroe, Michigan

🍎
My Varieties
Track your specific tree varieties (Honeycrisp, Elberta, Montmorency, Hass, Concord, etc.). Tap the row to expand. Inside: 🌱 Guide Me opens a 4-step variety wizard (zone + planting context + uses + traits → ranked recommendations). + Add Variety opens a modernized popup with 6 sections: Identity, Rootstock (for grafted fruits — filtered dropdown with Custom option), Characteristics, Disease Profile, Icon Appearance (live preview), and My Notes. Browse or search a catalog of 800+ varieties. Saved varieties show a custom fruit icon + a green 🌳 rootstock chip. The collapsed bar's icon adapts to your orchard: if you only grow cherries, it shows 🍒. 📷 Photos you add are automatically resized (1200px max, JPEG) so storage stays manageable — typically 15-25 photos per orchard fit comfortably.
🧴
My Products
Your product inventory — tap to expand. Inside: 🛒 Don't know what to buy? opens the Buyer's Guide wizard (4 steps → personalized shopping list). Full catalog of 73 spray products with search, fruit filter dropdown, filter buttons (All / Mine / Organic / Conventional), and formulation badges (CONC, WDG, WP, RTU, DUST, PREMIX, BAIT). Each product shows compatibility icons for your selected fruits. The app only recommends from your inventory. 📋 label link goes to the official manufacturer/EPA label. Collapsed bar shows a count badge like "6 products" with "3 organic · 3 conventional" below.
🪣

📚
Yearly Spray Guide
Stage-by-stage overview of what to spray and why for your selected fruit — all 20 fruit types from traditional orchards to citrus, grapes, tropical, and nut trees. Key stages marked with ⭐. Includes a "Getting Started?" box with minimum products for each fruit.
🌱
Growth Stages
Auto-detected via Growing Degree Days (GDD) from your location's weather. 8 stages from Dormant/Silver Tip through Post-Harvest. Uses the Baskerville-Emin single-sine method (base 50°F, from March 1) — the horticultural industry standard used by MSU Enviroweather, Cornell NEWA, and WSU DAS. Each fruit tracks independently with phenology offsets from MSU data (stone fruits bloom 10-14 days before apples; pears ~3-7 days before). Tap "What does this mean?" on the auto-detect card for the honest caveat that cultivar, microclimate, slope, and exposure can shift bloom by a week either way. Always override if your trees tell you different — tap any stage pill, or change the stage inline from within the Spray Wizard.
🌤
Weather & Forecast
7-day forecast with temperature, rain probability, wind, and spray condition ratings. Scores each day for spray suitability. Best window is typically a dry day before rain.
🎯
Spray Planner
Countdown to next spray, spray-by deadline, Coverage Health Dashboard (season grade, coverage %, gap count, rain exposure), and Top 3 Spray Windows ranked by weather. Shows context when your deadline is beyond the 7-day forecast.
📅
Year Timeline
Full-year visual of spray coverage for the selected fruit. Month-by-month growth stage bands, past sprays as dots, green "protected" windows (10 days after each spray), red gaps during critical stages, and the projected next spray. A red TODAY marker anchors your place in the year. Tap to zoom for a fullscreen landscape view with horizontal scroll and a stationary fruit header.
💊
Mix Recommendation
14-day calendar date picker with ★ on best day and red "DUE" on deadline. Shows ✅ Your Top Pick from your inventory, 🏆 Pro Pick popup with commercial upgrades (Indar, Pristine, Altacor, Streptomycin), 🛡️ Curative Backup for missed sprays, and 🔄 Other Options. For a more guided experience, tap the green 🎯 Start Spray Wizard at the top of the Spray Program — walks through weather → day selection → spray plan (with co-fruit grouping) → notes → log in one flow.
✏️
Manual Log & Spray History
Manual Log — for recording past sprays or custom mixes. Date defaults to today. Mix ratio auto-fills from the current fruit + stage protocol so you can accept or edit it. Also captures Varieties and Notes right on the form. Spray History shows chronological entries with product, fruits (colored pills), mix rates (🧪), variety detail (🌳), weather, and notes — regardless of which path was used to log.

Guide Wizards
Six step-by-step helpers for decisions that overwhelm new orchardists
🎯
Fruit Type Guide
Opens from 🌳 My Fruit Types or the Beginner's Guide. 4 steps: confirm USDA zone → describe your space and commitment → pick priorities (fresh eating, low-maintenance, kid-friendly, etc.) → rate your patience. Returns all 20 fruits ranked as ✅ Great Fit, ⚠️ Possible with effort, or 🚫 Not Recommended, with resistant-variety suggestions, time-to-fruit estimates, and honest caveats. Tap Add to add any recommendation directly to your fruits.
🎯
Spray Wizard
Opens from the top of the Spray Program. 4 steps: confirm weather window → pick a day from the forecast (best days ranked) → review the spray plan (product, mix rate, co-fruits sharing this product, curative backup, optional notes) → log with one tap. Key features: change your growth stage inline (no backing out), spray multiple fruits together (apples + pears at the same stage), add notes before logging, and save as planned to pin a future spray with a countdown banner. This is the recommended entry point for most sprays.
🛡️
Seasonal App-Limit Tracking
The app tracks how many times you've applied certain products this season and warns you before you exceed label limits or best-practice caps for resistance management. When you log a spray, if you're one away from the limit (e.g. spray #3 of 4 allowed Pristine apps) you'll see a yellow heads-up. At or over the limit, a red warning blocks the logging flow. Products tracked: Pristine, Heritage (strobilurins, max 4/yr — FRAC 11 resistance), Indar, Propiconazole (FRAC 3, max 4/yr), Immunox/Rally (myclobutanil, max 5/yr), Altacor (max 3/yr, IRAC 28), Delegate (spinetoram, max 4/yr, IRAC 5), Permethrin on peaches (label max 3/yr), and Kasumin on apple/pear (max 4/yr fire blight). Counts reset each calendar year.
🗓️
Year Rollover & Multi-Year Tracking
Your spray log is never wiped — everything you've ever logged is preserved across years. On January 1, Sprays YTD resets to zero (with a small "X in [last year]" subtext in Jan-Feb so you see the continuity), and the Year Timeline filters to the new year. Days since last spray keeps working across the year boundary. No action needed at New Year — just keep using the app. GDD (growing-degree-day) accumulation starts fresh each March 1, so Jan-Feb the stage auto-detect uses calendar-based logic for deciduous fruits ("dormant") and month-based logic for evergreens.
🍊
Evergreen & Tropical Fruits
Citrus, avocado, mango, guava, banana, and olive don't truly go dormant — they grow year-round. For these fruits, the app uses month-based stage detection instead of the deciduous dormant/post-harvest model: Mar-Apr spring flush, May bloom, Jun fruit set, Jul-Sep summer (pest pressure + oil sprays), Oct-Nov pre-harvest care, Dec-Feb winter rest. They're never forced to "post-harvest" in October the way an apple would be, because they're still actively growing/fruiting. Cold-hardiness recommendations for these fruits also use realistic per-fruit thresholds (e.g. Zone 8+ for citrus, Zone 9+ for mango) rather than a universal threshold.

🌱
Variety Guide
Opens from 🍎 My Varieties. 4 steps: fruit → planting fresh or adding to existing → intended uses (fresh, cider, baking, storage) + traits (disease-resistant, hardy, self-fertile) → recommended varieties filtered by your USDA zone and pollination needs. Badges show self-fertile, triploid, bloom group, and owned status.
🩺
Problem Diagnoser
Opens from 🔍 Disease & Pest ID Gallery. 3 steps: fruit → affected part (leaves, fruit, bark, whole tree, flowers) → select matching symptoms. Cross-references a research-backed symptom database and returns ranked likely causes with urgency levels (🚨 Urgent / ⚠️ Act Soon / ⚡ Moderate / ℹ️ Mostly Cosmetic), immediate actions, and direct links to full gallery entries with photos.
🌸
Pollination Checker
Opens from 🐝 Pollination & Pollinator Safety. 3 steps for apples, pears, and cherries: fruit → main variety → instantly see compatible pollinators (✅ Compatible, ⚠️ Marginal, ❌ Will Not Pollinate). Calls out triploids (sterile pollen, need 2 other varieties), cross-incompatible groups (Bing/Lambert/Royal Ann in cherries, Bartlett/Seckel in pears), bloom-time mismatches, and European/Asian pear incompatibility.

Orchard Notes
Your personal orchard journal — create, edit, organize
✏️
Creating Notes
Tap ✏️ New Note to open the editor. Add a title, write observations or plans, and optionally attach up to 6 photos per note. Notes are automatically dated when created. Tap 💾 Save Note to save.
📋
Viewing & Managing Notes
Saved notes appear sorted newest-first with title, creation date, and text preview. Each has ✏️ Edit and 🗑️ Delete buttons. Editing preserves the original creation date and adds a "modified" timestamp. Tap photos to view full-screen. Notes are included in data exports and can be restored from backups.

Header & Navigation
Getting around the app
🌡️
Header Bar
The top of the home screen shows your orchard identity. Corner badges (shown once set): 🌡️ Zone top-left, weather top-right — both tappable. Big app title: "Orchard SprayWise" — tap it to set a personal title like "Tim's Trees" (shows "on Orchard SprayWise" underneath when customized). Two matching pills below: 🏡 orchard pill (first word on line 1, second word on line 2 — tap to switch orchards or add new ones; orchard names limited to 1-2 words so they fit) and 📍 location pill (city on line 1, state on line 2 — tap to search city/ZIP, sets location, USDA zone, and weather together). Small utility pills below: ⚙️ Settings, ❓ Help, 🔗 Share, and 📖 New? (beginner's guide).
🧭
Bottom Navigation Bar
A customizable dark nav bar with 4 big buttons. 💧 Spray is always first (anchors home). The other 3 are user-customizable — tap ⚙️ Settings → 🎛️ Quick Access to pick from 16 options: 🎯 Plan (Spray Wizard), Log, 📝 Notes, ID, Convert, Mix Rules, Guide, Varieties, Weather, Timeline, FAQ, Mix Recommendation, 🌳 Fit (Fruit Type Guide), 🛒 Buyer (Buyer's Guide), 🩺 Diagnose, and 🌸 Pollinate. Defaults: 💧 Spray · 🎯 Plan · 📋 Log · 🔍 ID.

Tap-Again-to-Close
Tap a nav button whose section is already open and it collapses, returning you to the top home view. Fast to peek at a section and dismiss it without hunting for a close button.
🏡
Multiple Orchards
Fully-separate orchards with isolated data
🏡
Why Multiple Orchards?
Have more than one property? Ideal for growers with a home orchard and a rental property, or a Michigan farm and an Ohio farm. Tap 🏡 Orchards in the header to open the switcher.
🔒
What's isolated per orchard
Each orchard has its own location, USDA zone, fruit selections, varieties, product inventory, spray log, growth stages, sprayer size, orchard notes, and orchard name. Switching orchards loads an entirely fresh set of data.
🔗
What stays shared
Global preferences stay shared across all orchards: haptic feedback, sound, weekend/weekday priority, quick-access customization, backup reminders, onboarding flags, and ToS acceptance. No need to re-configure these for every orchard.
➕
Adding, switching, renaming, deleting
In the Orchards switcher: tap ➕ Add New Orchard → name it → optionally switch immediately. Each orchard row has Switch, ✏️ Rename, and 🗑️ Delete. Safety: you can't delete the active orchard (switch first), and you can't delete the last remaining one. The active orchard shows a green ACTIVE badge with location and zone.
🔄
How switching works
When you switch, the app saves the current orchard's data as individual snapshot entries (one per data type — varieties, photos, log, zone, etc.), loads the target orchard's snapshots into the live data, and refreshes the screen in place without a page reload. A green "🏡 Switched to …" toast confirms the switch. Weather re-fetches for the new location so you'll briefly see "Loading weather…" — normal. If anything fails mid-switch, a red banner shows the exact step so you can report it.
✏️
Customization
Tap the big app title at the top to personalize it (e.g., "Tim's Trees"). Tap the 🏡 orchard pill then the ✏️ pencil next to an orchard to rename it (1-2 words max to fit the pill). Use ⚙️ Settings to toggle haptic feedback and sounds, set weekend/weekday priority, toggle backup reminders, and customize 🎛️ Quick Access bottom-nav buttons. Sprayer size is per orchard (16oz bottles up to 50gal tow-behinds, or Custom) — remembered between sessions. All data is stored locally and never sent to any server.
🔗
Sharing & Backup
Export, import, and share your orchard data
📱
Share the App
Sends a Play Store link with a brief description of Orchard SprayWise. Works through Messages, Email, WhatsApp, or any app that accepts a link. Ideal for telling a friend or fellow grower about the app without sharing any of your data.
🌳
Share Current Orchard
Sends a snapshot of your active orchard (varieties, products, spray log, notes, location, zone) as a JSON file. The share message includes instructions for both recipients who have the app (Settings → Import → Add as new orchard) and recipients who don't (with a Play Store link).
ℹ️
Snapshot, Not Live Sync
Shared orchards are point-in-time copies. If you log a spray after sharing, the recipient won't see it until you share again. Each person maintains their own copy from that point forward. For ongoing collaboration, share periodically or have each person keep their own independent log.
💾
Backup, Export & Import
Tap ⚙️ Settings → 💾 Export. Pick what to include (current orchard, a specific orchard, or Everything — full backup), then pick how to save it. The picker is split into two clearly labeled sections:
📎 As a file — recommended: •📥 Download to this device — saves .json to your Downloads folder. •📤 Share file to another app — opens the share sheet with the backup as a real file attachment. Pick Gmail to email yourself the file, Drive to save to the cloud, or Files to keep it on your device. If your device can't attach files, the app warns you explicitly and offers Copy to Clipboard instead (it will never silently paste the backup as text into an email).
📋 As text — if file download isn't working: •📋 Copy to clipboard — copies the backup text. Paste it into Gmail, Google Keep, a text file on your computer, or GitHub. •📄 Show text on screen — displays the backup in a big text box with a Copy All button. Last-resort escape hatch.
Import has a matching set of methods: 📋 Paste from Clipboard (if you have backup text in your clipboard), 📝 Paste into Text Box (paste manually), or 📁 Upload .json File (classic). The app detects the backup format (single-orchard or full) and offers the right options — Replace current orchard, ➕ Add as new orchard, or ⚠️ Replace everything for full backups.
All data lives in local browser/app storage — nothing is sent to any server. Back up periodically, especially before major changes. The app also nudges you with Backup Reminders after sprays (toggle on/off in Settings).
