Vegetable Garden Full of Oxalis

Question

My vegetable garden is full of Oxalis.  How do I get rid of this as I want to plant a rose garden in its place?

Answer

Oxalis is a bulbous weed which is very problematic. Once it is in your garden, the bulbs multiply and spread very easily.

Over the years there have been a number of herbicides produced that can kill oxalis, however they have always been non-selectors, killing surrounding vegetation. They’ve also had considerable soil residual problems meaning you could not grow plants, especially vegetables in the same area for a considerable time afterwards. This is not ideal considering you want to establish a new rose garden in the location.

Unfortunately, the only really effective way to get rid of oxalis is to remove all of the bulbs by hand. Admittedly, it’s a tedious task but well worth doing.

Divide the area up into sections then dig down 20-30cm and sieve the soil to catch all the bulbs. Alternatively, you can dig up the area, pen it off and put chickens in there if you have them.

Be sure not to transplant the soil to other areas of the property as it will only take a few bulbs to start the problem again!

Once all the bulbs have been removed, replenish the soil with Daltons Garden Time Compost and Garden Time Planting Mix.
