have a bad problem with oxalis in our vegetable garden. What is
the safest and quickest way to eradicate this weed?
there is no quick fix to eradicating oxalis from the garden. The
best thing to do would be to either hand weed, making sure you get
all of the parent bulbs and pups (outlying baby bulblets), or spray.
If you spray, you will have to have a clear vege patch with no vegies
in it. You can use Roundup Renew, or Yates Zero. You can also use
Yates Amitrole when the plant is in full leaf. Be careful that you
do not get excess residue on the soil, as this chemical has a soil
residue that can last for sixmonths. As we are coming up to autumn
and winter, it may even pay for you to sterilise your soil with
Yates Basamid granules. If any oxalis occurs again after sterilising
and spraying, it should not be too hard to eradicate.
