Rowan Guardian for Home Growers — AI Cultivation for Your Backyard Garden

The Challenge

Gardening Shouldn't Be Guesswork

🤔

What's Wrong With My Plant?

Yellow leaves, brown spots, wilting — you see a problem but don't know if it's overwatering, disease, a pest, or nutrient deficiency. Google gives you 50 conflicting answers.

🌡️

Weather Surprises

A late frost, unexpected heatwave, or sudden rain can undo weeks of work. Most gardeners find out too late to protect their plants.

📝

Can't Remember What Worked

"What fertilizer did I use last year? When did I plant those peppers?" Without records, every season starts from scratch.

How Rowan Helps

Your Personal Garden Brain

Rowan's Home Grower experience is designed for people who love plants but aren't professional botanists. Everything is clear, friendly, and actionable.

☀️

Weather-Aware Dashboard

Your dashboard shows real-time weather for your location — temperature, humidity, VPD, UV index, precipitation, and ET₀. Rowan correlates this with your plants' specific needs and proactively warns you about coming weather events.

Example: "Frost expected tonight at your location (34°F). Your outdoor tomatoes and peppers need to be covered or brought inside by 6pm."

📸

AI Photo Diagnosis

Take a photo of any plant problem. Rowan's multi-pass diagnostic pipeline analyzes the image against thousands of conditions, cross-references your sensor data and growth stage, and returns a specific diagnosis with actionable home remedies.

Example: "This appears to be early blight (Alternaria solani). Confidence: 87%. Remove affected leaves, apply neem oil solution, and improve airflow between plants."

🌱

Garden & Plant Management

Organize your plants into gardens (indoor, outdoor, greenhouse). Track each plant's health score, growth stage, watering schedule, and feeding history. Rowan learns your garden's patterns over time.

Maria's setup: "Backyard Veggie Patch" (outdoor, 3 plants) + "Kitchen Herb Window" (indoor, 3 plants) — 6 plants total, all healthy.

📖

Grow Log Journaling

Every watering, feeding, observation, photo diagnosis, and AI consultation is automatically logged. You can also add manual notes. Everything is searchable, filterable by date or plant, and exportable.

Think of it as: A smart garden diary that writes itself — so next season, you know exactly what worked.

💬

Friendly AI Mentor

Rowan speaks your language — not academic jargon. Ask anything: "Why are my basil leaves curling?" "When should I plant cucumbers in Florida?" "How do I make compost tea?" Every answer is evidence-tagged and confidence-scored.

Voice coming soon: Hands-free voice commands and spoken responses are on the roadmap — grow without stopping to type.

Frost, flooding, pest outbreaks, power failures, heatwaves — Rowan generates customized emergency plans with checklists, supply lists, recovery timelines, and printable PDFs tailored to your specific garden.

Available scenarios: Frost/freeze, extreme heat, storm/flooding, pest outbreak, disease outbreak, drought, power failure, and wildfire/smoke.

Ask Rowan — Home Grower Mode

My tomato leaves are turning yellow on the bottom. Is that normal?

Great question! 🌿 Lower leaf yellowing on tomatoes is actually quite common and usually one of two things:

[Fact] As tomato plants grow, they naturally redirect energy to new growth, causing older bottom leaves to yellow and drop. This is called natural senescence and is completely normal.

[Inference] Based on your current EC reading of 1.2 mS/cm, nitrogen levels look adequate, so this is likely natural senescence rather than a deficiency.

[Action] Remove yellowed leaves cleanly at the stem. This improves airflow and reduces disease risk.
