Everything I'm Seeding in April

April is when gardeners need to start being mathematicians and professional organizers, trying to find space for all the seedlings that need to get into trays on time. It’s also the first time this year you’ll start succession seeding, both indoors and out. Succession seeding is one of the real benefits of growing your own seeds: It means you can grow one or two of a variety instead of needing the space for a whole six pack you’d pick up at the nursery. Grow a mixed tray of vegetables or herbs now, and start another one in a few weeks.
