it does work. you need to keep spraying new growth as it comes up.

Wally Richards advises the use of 1 heaped tablespoon of baking soda,
1 litre of warm water & 1 ml of Rainguard.
Apparently the commercial product is only baking soda anyway.
As proof of it not damaging other plants, you can use the same spray to control mildew on other plants.

This sounds like more organic than using roundup, but what's rainguard?

Replying to Pearly's question about her hedge - I believe it is called Escallonia

HAve lived with the dreaded Oxalis for over 40years and hae just forked it up and thrown it on the lawn where it makes a nice cover and is nice to walk on. The section had been used as a dump by the earlier neighbours (it was a dirty little gully that's why we could afford it) and had oxalis and twitch are the major species in the lawn now but when they rear heads in garden just throw back onto the lawn and we survive and garden is reasonably productive.
Admittedly there are times when they get a bit thick in places but still reduce infestation in a couple of years. Weeds are just things we don't have a use for, (yet). Anyone know of a use for oxalis?

This afternoon I pulled about 2 buckets of the dreaded oxalis out and noticed they didn't have any bulbs attached was just a long fleshy root do you think pulling them at this time of the year that the bulbs have not yet had time to mature and I may be lucky at reducing the next seasons growth. Have tried the baking soda recipe and only seems to knock a few back, and have had great success with round up but will only use where it will not harm other plants

I have used roundup but it is only a temporary solution. Spent a week digging out one garden a month back and so far so good. The garden centre told me to use hydrocytlyte spray on the yellow variety because DTO doesn't work on that type. However can only use this spray where there are no other plants and you can't use it where you want to grow veges so will try that when the weather dries out a bit on the paths and simialr places.

Hi Bobbity, I eventually rid most the oxalis out of my garden through digging with a small fork down to the bulbs. Very labouring and annoying but worth the effort in the end. Good luck in getting rid of it.

Oxalis came to my garden through purchasing some soil from a garden supply centre.

This outfit sold me on their `specially mixed' soil by telling me what they put in it, that they mixed and packed it up themselves etc.

It was a little more expensive (and came in smaller bags than you get in the big stores like Mitre 10, Bunnings, etc) but I thought it would be better. Silly me!

They forgot to mention that oxalis was part of the recipe.

I had purchased a whole lot of terracotta pot and the soil I got from this outfit was dedicated for the plants to go in those; that's how I know where the oxalis came from.

Anyway, you can buy a product called `Death To Oxalis' (It's about $25 a packet). I believe it will work on any plant except bulbs - but you need to read the packet to be sure.
