What is an Invasive?

  • Usually Non-native. There can be aggressive native plants.
  • No or few predators keep it in check
  • Spreads aggressively. Sometimes it chemically suppresses other competing plants.
  • Contributes to monoculture as it takes over.
  • Reduces diversity.
Lesser celandine

Why do we care about invasive plants?

  • Monoculture is boring.
  • Native plants are crucial for biodiversity. (Read about Natives and Keystone plants)
  • Native plants are adapted to our conditions (manage in stormwater and drought)

How to remove invasives?

  1. Pullout as much as possible. Weaken if you cannot remove.
  2. Smother.  With cardboard or plastic (solarize).
  3. Girdle with knife.
  4. Last choice: Limited poison. Cut and paint with Garlon or similar. Or girdle with garlon. Do not spray. Poison kills soil microorganism, good fungi. Vinegar with salt requires constant reapplication and may damage soil.

Nature abhors a vacuum


Remember to plant or seed after removing invasives. Plant densely to keep out weeds.
