If you’re new to growing vegetables or just need a refresher, here’s a basic planting calendar to get you started. The dates are approximate and will vary depending on your location, the weather, and the time you have available. If you aren’t able to grow your own seedlings, you can buy them at farmers’ markets, food co-ops, local greenhouses and farm stores in the spring and just follow the transplanting dates below. Visit our fact sheets page for more information on the basics of organic vegetable gardening, making your own seed starting mix and more.
