- Photo diagnosis — snap a leaf, get an answer in seconds
- Personalized planting calendar by ZIP code
- Garden tracker for beds, containers, and raised beds
- Harvest timing reminders sent to your phone

Backyard Masterclass
The complete home food-growing system I built after 40 years of doing this the hard way. Six comprehensive modules, 50 crop guides, and everything between "I have bare dirt" and "the pantry is full."
Not a generic gardening book. Zone-specific, crop-specific, season-specific. If you're starting from scratch or feel like you've never had a system, this is it.
- 6 comprehensive modules from soil prep to long-term storage
- 50 crops with full zone-specific growing guides
- Organic pest identification + treatment for every crop
- Harvest timing and food storage guides
- Companion planting maps for all 50 crops
- One-time purchase — yours forever
