What happens when a weed is controlled?
 |
- Hopefully, native plants grow back!
- However, if weeds are removed too quickly (e.g. hand-pulled),
new weeds (called replacement weeds)
can take advantage of the empty space and move in before native
plants get a chance to grow.
- Once weeds are removed, it is important to come
back and check the site to make sure new weeds haven't
taken over or the old weed has grown back.
- Sometimes we should give the native bush a helping hand by replanting
the area with native plants. This can also help to make
sure there are no problems with soil
erosion and that wildlife in the area still have shelter
and food available once the weedy plants are removed.
