Using Integrated Pest Management (IPM) strategies

IPM means getting to know your pests.

  • When is the pest MOST vulnerable, infective, or invasive?
  • When is the pest most vulnerable to least-toxic management strategies?
  • What is the least-toxic management tool that can be used successfully?

IPM optimizes plant health through the following:

  • Managing garden and landscape soils to promote drainage and aeration
  • Maximizing soil health by adding organic matter and properly timed fertilizers.
  • Pruning and irrigating based on the needs of particular plants.
  • Knowing the plant's level of susceptibility to pest damage.
