If you start vegetable plants indoors, it is often helpful to list seeding dates on a calendar so that plants are ready for transplanting at the proper time. To do this, choose your transplant date and count back the number of weeks necessary to grow your own transplants. For example, cabbage, broccoli, and cauliflower are usually transplanted in late March to early April. It takes 8 weeks from seeding to transplant size. Plants should be seeded in early February.

Below are examples of some common vegetables grown for transplants and a recommended date for seeding. Dates are on weekends as this is when many homeowners have the most free time. The dates are not set in stone, and a week earlier or later will not ruin the plants. Keep notes on how well the transplants did so you can tweak the planting schedule. Your conditions may result in plants that need a bit more or a bit less time.
