Frequently Asked Questions
What zones and cities do you cover?
GrowSmart covers 1,400+ cities across 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. We include major metros, suburbs, and rural areas. If your exact city isn't listed, choose the nearest one — frost dates will be close.
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.

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?

It also includes succession planting automation and companion planting with actual reasons, not just checkmarks.
