Guides grounded in measurements, not scraped averages.
Most gardening advice online is the same paragraph, rewritten. Greenshoot’s guides start from measured growing data — real germination temperatures, days to harvest, water and pH needs for 644 plants — cross-read with historical horticultural texts that predate the SEO farms.
- Real numbers on every guide: germination temp, days to harvest, spacing, pH
- Grounded in measured records and public-domain horticultural literature
- Every guide is judged on accuracy, groundedness, specificity, actionability, and safety — only passes ship. 475 live so far.
/ the coach
A coach that grows with you — not a one-off diagnosis.
Plant-ID apps answer once and forget you. Greenshoot’s coach works on a timeline: send a photo at each stage — germination, seedling, first flower — and it judges health and growth against what your plant should be doing by now, in your zone.
- Photo check-ins as you grow, not just when something looks wrong
- Progress judged against expected timelines from the measured data
- Understands your hardiness zone, and asks for it once
- You log what you did — the coach follows up on whether it worked

/ the grow log
Every check-in makes your garden smarter.
A grow log is the atomic unit of greenshoot: what you planted, what you saw, what you did, and whether it worked. Season over season, those logs become a care database for your exact patch of ground — your soil, your beds, your microclimate. Advice that compounds instead of resetting every spring.
Next up: 394 zone-specific planting calendars, so the timeline knows your frost dates before your first check-in.
