March Gardening Tips

  • Trees, shrubs and perennials may be planted as soon as they become available at local nurseries.
  • Loosen winter mulches from perennials cautiously. Re-cover plants at night if frost returns. 
  • Heavy pruning of trees should be completed before new growth starts. Trees should not be pruned while the new leaves are growing. 
  • Ornamental grasses should be cut to the ground just as the new growth begins. 
  • Apply broadleaf herbicides for control of cool-season perennial and annual weeds. 
  • Plant peas, lettuce, radishes, kohlrabi, mustard greens, collards, turnips, spinach and onions (seeds and sets) outdoors. 
  • Delay vegetable planting if the soil is too wet. When a ball of soil crumbles easily after being squeezed together in your hand, it is dry enough to safely be worked. 

Plastic Pot Recycling Update 2022

We regret to report that the Plastic Pot Recycling program has been cancelled. Garden centers that have had pot recycling collection trailers in the past are no longer accepting garden plastics. Please see the Plastic Pot Recycling: Update and Perspective blog entry for more information about the program's cancellation. Additional questions about pot recycling can be submitted to the Green Resources Info Service at greenresources@mobot.org.
