About
GrowSmart is a garden planner that builds your planting schedule from your city's frost dates. Choose your city and your plants, and it lays out when to start seeds indoors, transplant, direct sow and harvest, across spring, summer and fall.
It replaces googling planting dates, generic calendars and spreadsheets.
FROST DATES FOR YOUR CITY
Schedules are calculated from your own city's average last and first frost dates, not a regional guess. Canadian dates come from Environment Canada 1991 to 2020 climate normals and US dates from NOAA 1991 to 2020 normals. Covers Canada, the US, the UK and Ireland.
THREE-SEASON PLANNING
Spring, summer and fall windows in one plan, so a bed that grows peas in April can grow beans in June and garlic in October.
SUCCESSION PLANTING
Repeat sowings of lettuce, beans, radishes and other quick crops are scheduled for you, so the harvest keeps coming.
COMPANION PLANTING WITH REASONS
See which plants help each other and which conflict, and why. Basil next to fennel gets a warning and an explanation, not just a red mark.
BED LAYOUT
Lay out raised beds, rows and containers with drag and drop. Spacing is handled for you, and the planner flags poor companions and crops that come back to the same spot too soon.
THIS WEEK
One clear list of what to sow, transplant, water, feed and harvest this week.
SAGE, YOUR AI GARDEN ASSISTANT (PRO + SAGE)
Ask garden questions in plain language. Sage knows your city, your frost dates and what you are growing. Send a photo of a struggling plant and Sage suggests the likely cause, whether a pest, a disease or growing conditions.

Plan in the garden without a signal. Start planning right away with no sign-up. An account is optional, for syncing across devices.

What's New in GrowSmart
1.0.4
September 30, 2026
Ask Sage to design a layout for your bed, then apply it in one tap. Fill this bed now places your plants, moving them to the nearest open square instead of leaving them out. Companion warnings explain why two plants clash. Moving plants in your beds works better by touch. Your seed list counts what is planted in your beds. Signing in from Sage in the planner is fixed.
