Planting Date Calculator
Use your frost dates and crop choice to estimate seed-starting, direct-sowing, transplanting, and harvest windows. The dates are ranges because soil warmth, wind, and spring mood still matter.
Planting notes
Before planting
A late cold spring, cold soil, wind exposure, or tender seedlings can make waiting the better choice. Waiting a week is not failure; it is often easier than rescuing stressed tomatoes, peppers, basil, cucumbers, or beans after they were planted into rough conditions.
How to use this calculator
Start with your last frost date, then choose the crop. If you also know your first frost date, the calculator can show when fall or short-season limits start squeezing the crop.
Common questions
Are planting date calculator results exact?
No. They are date ranges based on frost timing and crop behavior. Local weather, soil temperature, microclimate, variety, and plant condition still matter.
Do raised beds let me plant earlier?
Sometimes raised beds warm faster than in-ground soil, but tender leaves can still be damaged by cold nights. Use the calculator as a starting point, then check the forecast and soil warmth.
Should beginners start every crop indoors?
No. Tomatoes and peppers often benefit from indoor starting, while carrots, beans, and many quick crops are usually simpler to direct sow when conditions are right.
