Seeds to Start in May

category: Articles and Instructions category: Garden Resources category: Seed Talk

As far as the calendar is concerned, spring is half over, despite the sense for many of us in 2017 that is yet to begin! There are still dozens of seeds to start in May. It can still be cold at night, so some seeds will continue to benefit from starting indoors in a warm room. Most seeds will germinate faster and more evenly if heated from below with a heating mat. Other seeds actually prefer cool soil for germination, and they can be direct sown in May here on the coast.

Start these seeds indoors in May:

Asparagus (start indoors in the first week for transplanting mid-June)
Brussels Sprouts (sow indoors last week in May for early August transplanting)
Cauliflower (start indoors for transplanting June to August)
Cucumbers (start them indoors in the second week in May, transplant in June)
Pumpkins & Squash (start indoors before the 15th for transplanting in June)
