Meet Sage — Your AI Garden Assistant
Ask questions, identify problems, get advice based on your actual garden.
Pest & Disease Identification
Upload a photo and Sage identifies the problem. Get a diagnosis and treatment plan based on your specific plants and zone.
Ask Sage Anything
Sage knows your frost dates, your zone, and your active plants. Ask about timing, spacing, companion planting, or anything growing-related.
Garden Layout Advice
Describe your space and Sage suggests what to plant where, factoring in companions, sun requirements, and succession timing.
Sage is included in the Pro + Sage bundle. Free users get 3 queries to try it.
Sage designs your bed layout
Your personalized week, calculated from your local frost dates
No generic spring calendar. Your week reflects your city, your plants, and where you are in the season.
- ✓ Start tomatoes & peppers indoors
- ✓ Direct sow spinach and lettuce
- ✓ Transplant hardened-off brassicas
Dates calculated from your local last frost, not a generic calendar.
Everything You Need to Grow More Food
For gardeners who want to do it right — whether it's your first raised bed or your fifth season.
Frost-Smart Scheduling
Planting dates automatically calculated from your local frost dates. No more Googling "when to plant tomatoes."
Companion Planting Guide
Full companion matrix for all 195 plants shows you what grows well together — and what to keep apart. With reasons, not just checkmarks.
Succession Planting
Stagger your plantings for continuous harvests. Get lettuce, beans, and radishes all season instead of one glut.

Frequently Asked Questions
What zones and cities do you cover?
GrowSmart covers Canada (all 10 provinces, zones 2a–8b), the US (all 50 states, zones 2a–12a), the UK & Ireland (zones 7a–10b), and Western Europe including France, Germany, Spain, Italy, Netherlands, Scandinavia and more. Real frost dates for your exact city. We include major metros, suburbs, rural areas, and small towns. If your specific city is not in our hand-curated catalog, our global lookup resolves it on demand.
Where does the frost date data come from?
Canadian frost dates come from Environment Canada 1991–2020 Climate Normals and NRCan Plant Hardiness Zone data (2024 update). US data is sourced from NOAA 1991–2020 Climate Normals and the USDA 2023 Hardiness Zone Map. UK and Ireland data is based on Met Office 1991–2020 Climate Normals. European data draws from national meteorological services including DWD (Germany), Météo-France, KNMI (Netherlands), AEMET (Spain) and others.
What's included in the free plan?
The free plan gives you spring planting schedules for up to 10 plants, basic companion planting info, and works on all devices — including offline. No account required. Pro unlocks unlimited plants, full three-season scheduling (spring, summer, and fall), succession planting, and care tracking.
Do I need to create an account?
No. You can start planning immediately — no sign-up, no email required. Your data saves locally on your device. You can also create a free account to save your garden across devices and unlock features like Sage AI.
Does GrowSmart work offline?
Yes. Install it to your home screen and your full schedule, plant data, and care log work without an internet connection — so you can check your planting dates right in the garden.
How is this different from other garden planning apps?
Most garden apps give you generic calendars or focus on aesthetics. GrowSmart calculates every planting date from your specific city's frost dates — and plans across three seasons, not just spring. It also includes succession planting automation and companion planting with actual reasons, not just checkmarks.
