January Gardening Tips

  • If overwintering dormant, tender perennials or tropicals in a garage or basement, monitor the temperature and moisture levels closely to avoid freezing, drying out or rotting due to overly wet, cold soil. 
  • Check stored summer bulbs such as dahlias, cannas and gladioli to be sure they are not rotting or drying out.
  • To reduce injury, allow ice to melt naturally from plants. 
  • Inventory the plants in your home landscape. Note their location and past performance. Plan any changes needed for the upcoming growing season. 
  • Try a germination test of left over seeds before ordering new ones for spring. Roll up seeds in a damp paper towel, keeping them moist and warm. Check for germination in a week. If fewer than half of the seeds sprout, order new seed. 
  • Use salt with caution or not at all around plants or you risk causing salt damage. The damage may not be evident until late winter or early spring as temperatures warm. 

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.
