For the Spring:
Your planting strategy:
Cole crops like broccoli, cauliflower, and cabbage can be direct seeded into your garden around February 21, assuming the ground can be worked, but it's better to start them indoors around January 24 and then transplant them into the garden around March 14. Do the same with lettuce and spinach.

Plant onion starts and potatoes around February 3. Sow the seeds of peas (sugar snap and english) at the same time. If the ground is still frozen, then plant these as soon as the ground thaws.

Do you want to grow tomatoes, peppers, and eggplants? Start these indoors around January 24. Then, around March 30 you should start watching the weather forecast and, as soon as no frost is forecast, go ahead and transplant those into the ground.

Now, for all the summer vegetables like beans, cowpeas, corn, squashes, pumpkins, cucumbers, watermelons, gourds and sunflowers, you should plant those seeds directly into the ground around April 3, or if your soil is still very cold, once the soil is near 60° F in temperature.

Okay, now here are the cold, hard numbers, along with specific plants:

For the Fall:
Your fall planting strategy:
Gardening in the fall can be much more challenging than spring planting, because you are in a race to get your crops mature and harvested before the winter frosts begin, around October 27. This means you need to consider how much time each variety needs between planting and picking. Those numbers vary widely between different varieties of the same kinds of plants! Usually the "Days to Harvest" are present on the seed packet.

Most tomatoes, peppers and eggplants, for example, require around 100 days to harvest, therefore you'd want to transplant those into the ground around July 19. Anyway, it's important to remember that the numbers in this fall planting guide are only a starting point for you! Good luck and good gardening to you.

Fall is the time to plant garlic. Around September 12, take your cloves apart and plant the toes about 3 to 4 inches deep. This may not be accurate! Garlic dates vary wildly around the country. The way to be sure is to use a soil thermometer. When the soil temperature is 60° at a depth of 4 inches, then plant your garlic.

Cole crops like broccoli, cauliflower, and cabbage can be direct seeded into your garden around August 18, but because of the heat during that time of year, it's better to start them indoors around June 29 and then transplant them into the garden around August 8. Do the same with lettuce and spinach.

Sow peas directly around August 13.

Now, for all the usual hot weather veggies like beans, cowpeas, corn, squashes, pumpkins, cucumbers, watermelons, gourds and sunflowers, you should plant those seeds directly into the ground around July 14.

How accurate is all this? For nearly all locations, we are confident in the dates. There are, however, some difficult areas of the world that don't match up perfectly with the dates we have given. For that reason, we recommend you use this guide as a very good starting place, but don't interpret the dates as absolutely perfect for every location.
