The best time to plant a vegetable garden depends on the vegetables you're growing and will vary based on your region-specific weather…
Every vegetable has unique needs. Some are hardier and may actually grow better after being exposed to a hard frost or two (“hardy”), some don’t like but will survive light frosts (“half hardy”) and others must avoid frost at all costs (“warm season”). And while most vegetables will take as much sun as you can give them (“full sun” – at least 6 hours), others like or will tolerate partial shade.
To get even more specific, each plant has a desired range of soil temperatures that it prefers for germination (even though germination may occur outside of those ranges). Generally speaking, the higher the soil temperature within the plant-specific desired range, the faster the plant will germinate.
Inexpensive soil thermometers can be purchased to determine when your soil’s ready for each plant, and insulation in the form of black plastic mulch or landscaping fabric can get it there a few weeks ahead of time.
When planning your vegetable garden layout and the planting time of each crop, don’t forget to take the companion planting charts and your annual vegetable crop rotation into account.
The following chart sums up the weather requirements for each vegetable type. Follow the links for more vegetable-specific information…

*Very Hardy to Hardy - Will survive hard frosts and can be planted 2 to 3 weeks before the average date of the last 32 degree F (0 degree C) temperature in spring. Half Hardy – Will survive light frosts. Seeds germinate at low soil temperatures and can be planted 2 weeks before the average date of the last 32 degree F (0 degree C) temperature in spring. Warm Season – Will not survive frost and their seeds will not germinate in cold soil. Plant them at about the average date of the last 32 degree F (0 degree C) temperature in spring |
