November Gardening Tips

  • Continue watering, especially evergreens if soils are dry. Soils must not be dry when winter arrives. 
  •  Remove spent flowers and foliage of perennials after they are damaged by frost. 
  • Plant tulips now.
  • To prevent injury to turf grasses, keep leaves raked up off the lawn. 
  • Mulch flower and bulb beds after the ground freezes to prevent injury to plants from frost heaving. 
  • Be sure to shut off and drain any outdoor water pipes or irrigation systems that may freeze during cold weather. 

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.
