Onions growing in a garden
  • Late summer and early fall is a great time to plant cool-weather crops like lettuce, radishes, and spinach.
  • September is the best month to plant garlic and onions.
  • Continue to harvest veggies in the garden. Rain or cold may cause them to become moldy.
  • Plant flower bulbs like crocuses and daffodils in containers to grow inside over the winter.
  • Create an outdoor flower garden for early spring flowers. Plant bulbs like tulips, crocuses, or daffodils.
