Use these dates as a guideline for your seed-starting calendar. Identify when you intend to transplant seedlings into the garden and count back to determine how many weeks earlier you need to start the seeds.
Crops such as Brussels sprouts, cauliflower and broccoli do best as transplants so they reach maturity before the heat arrives. Leeks are typically established as transplants rather than direct-seeded and seeds should be started 10-12 weeks before the transplant date. They can be difficult to find at garden centers so growing your own is typically necessary. It’s time to get a plan together to make sure you’ll have veggie starts this spring.
