October Gardening Tips

  • Houseplants and other tropical plants should be brought inside by early to mid-October at the latest. Before bringing them in, be sure to check for spider mites, scale, whiteflies, mealybugs, and fungus gnats. 

  • The average first frost date for St. Louis, MO, is October 15-20th. 

  • Plant garlic and shallot bulbs by mid-October.  

  • Plant daffodils and other spring bulbs by mid to late October; tulips can be planted until the ground freezes.  

  • Trees and shrubs can be planted for fall through November, water thoroughly, and provide mulch for winter protection. 

  • Lawn seeding should be done by mid-October. 

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.
