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.
