No generic spring calendar. Your week reflects your city, your plants, and where you are in the season.

Frequently Asked Questions
What zones and cities do you cover?
GrowSmart covers Canada (all 13 provinces and territories, zones 0b to 9a) and the US (all 50 states and DC, zones 2a to 12a), from major cities to small towns. A Canadian or US town that is not on our list gets frost dates from the weather stations nearest to it. The UK and Ireland have approximate frost dates for listed cities, and so does Western Europe including France, Germany, Spain, Italy, the Netherlands and Scandinavia. That is about 360 listed cities in all; a town that is not listed uses the nearest listed city within 150 km, or has no frost dates yet.
Where does the frost date data come from?
Canadian frost dates come from Environment Canada 1991 to 2020 climate normals and US frost dates from NOAA 1991 to 2020 normals, using the median of up to three nearby weather stations. Hardiness zones come from NRCan for Canada and the USDA for the US. Frost dates for the UK, Ireland and Western Europe are approximate figures for listed cities, not yet drawn from station records.
What's included in the free plan?
The free plan is: up to 10 plants, the spring schedule plus fall garlic and shallots, one bed. It also includes basic companion planting info and works on all devices, including offline. No account required. Pro unlocks unlimited plants, unlimited beds, 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 planner apps give you a short plant list, a US calendar and a one-garden free plan. GrowSmart gives you 196 plants plus your own, dates from local weather stations in Canada and the US, all three seasons, and a free plan with no account or card.
Free planting guides
A seed starting and fall planting calendar, a companion planting chart and a succession planting guide.
