What to do in May instead

Plan next season's beds

Sketch what goes where before spring — rotating plant families between beds breaks pest and disease cycles.

Order seeds early

Popular varieties sell out by late winter. Ordering now means everything is on hand when indoor seed-starting begins.

Prep tools and trays

Clean pruners, test old seed for germination on a damp paper towel, and wash seed-starting trays so they're sterile for the first sowing.
