Troublesome Oxalis
I
WOULD appreciate your advice on how to rid my garden of Oxalis.
I HAVE found the best way to
eradicate Oxalis is to hand weed, making sure you get as
may of the bulblets as possible, and just keep hand weeding as new
plants appear. Hand weeding may not be practical in a large area
and Activated Amitrole or Amitrole is the most effective spray for
Oxalis. Repeat sprays will be necessary.
To get the best control, spray in spring and autumn when plants are actively growing. Amitrole has a short soil life and can be sprayed around established trees and shrubs as long as care is taken not to get spray on the foliage.
