June Gardening Tips

  • Water trees and shrubs during prolonged periods of drought. Water turf as needed to prevent drought stress.
  • Soaker hoses and drip irrigation systems make the most efficient use of water during dry times. 
  • Watch for bagworms feeding on plants such as juniper and arborvitae. 
  • Plant tropical water lilies when water temperatures rise above 70 degrees F. 
  • Pruning of spring flowering trees and shrubs should be completed before the month's end.
  • Mow lawns frequently enough to remove no more than one-third the total height per mowing. 
  • Plant pumpkins now to have Jack-o-lanterns for Halloween. Start seedlings of broccoli, cabbage and cauliflower, to grow transplants for the fall. 
  • As soon as cucumber and squash vines start to 'run', begin treatments to control cucumber beetles and squash vine borers. 
  • Summer fruiting raspberries are ripening now. 

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.
