  • Plant winter lettuce, peas, carrots, cole crops, and Asian greens.
  • Harvest winter squash and pumpkins before frost, when their skin is hard enough to resist pressure from your thumbnail.
  • Set out transplants of calendula, primroses, larkspur (Consolida ambigua), snapdragons, bachelor's buttons (Centaurea cyanus), stock (Matthiola incana), and pansies.
  • Refrigerate spring bulbs for 6 weeks to plant later this fall.
  • Pick ‘Bartlett' pears for ripening indoors, but allow Asian pears and ‘Seckel' pears to ripen on the tree.
  • Protect grapes from birds and wasps by covering the ripening clusters with brown paper lunch bags.
