Just before Xmas I purchased six large bags of compost from The
Warehouse for my vegie garden, now it is infested with oxalis. I have
been digging out hundreds of the bulbs as the leaves appear.
Despite this my vegie garden is thriving everything is growing at a rate
of knots. (including the oxalis).
There is something called Death to Oxalis , but people seem to have
varying degrees of success with it.
I guess I will be picking the bulbs out for some time to come. <sigh>

Purchased compost should be free of oxalis. The composting heat should kill
everything.
Perhaps it was dormant in your soil.
Try sieving a bit of the compost if you still have some, and complain if you
find oxalis bulbs.

I just brush it with Roundup.

Go back to The Warehouse and demand an explanation.
They do have a money back guarantee and, I believe, a good reputation.
It's easy enough to test compost for weeds.
However it's quite possible that the oxalis was already in your garden.

Plants only absorb simple chemicals in ionic form through their roots.
There is much fuss about organic fertilizers etc. That is nonsense, the
plants cannot absorb the organic molecules only the simple inorganic
chemicals that arise from the decay of organic material. Similarly
there is much nonsense talked about hydroponics. Indeed hydroponics is
the ideal system as it provides the plants only with that which the can
absorb.

What chemicals? Roundup only works on exposed plant material, leaves
and green stalks. On the soil it is neutralised immediately. It is not
absorbed through the roots. Sodium chlorate however is a different matter.

DTO claims to not kill the other plants and even be safe to drink:

The think is, you need to keep persisting with it until the residual
bulbils peter out.

I wouldn't be too fixated on 'chemical free'. The world we live in and

The answer's quite simple, don't put it on your vegetables! Who would
anyway???

It's taken me about eight years to get rid of the oxalis at my place.
There's *possibly* still some left, it's hard to know. I generally use
Geo's trick, paint some glyphosate directly onto to the stuff. It works
a lot better than trying to pull it out.

In my opinion, you'll never get rid of Oxalis by pulling it out.
Particuarly if it's in areas with other plants you don't want to
disturb. If you're prepared to lose your other plants, then loosen up
the soil as much as possible and pull the Oxalis out very carefully
trying to avoid breaking it off. An old kitchen bread knife or similar
may help in that process. Good luck, it will take years. Stick with
it, you'll get there eventually.

But if you ask me (and I know yer not! :) - glyphosate is amazing and
revolutionary stuff - compared to the hard way. I use it every few
weeks. It saves me untold hours of labour. I use it carefully, on calm
days only and hit only the weeds I wanna kill. For this reason, I may
still have some Oxalis around the gold fish pond, which I don't spray
too close too.

There are a number of glyphosate based weedkillers, Roundup is the best
known. There are many others some of which are absorbed by the leaves,
like glyphosate, and some through the roots. Sodium chlorate (not to be
confused with sodium chloride) is a simple chemical, perhaps hard to get
as it is an oxygen donor that can be used in explosives, which kills
though the roots. It buggers the soil for a long time.

It has been since I have been here. Somebody sprayed it several months
ago and it was bare when I arrived. It has since been built up and had a
lot of compost added to it.

The seller of "death to oxalis seems to have had reasonable commercial
success.
The approx $20 small packs contain only baking soda - about $0.50 worth.
It (baking soda solution, with a dab of dishwash detergent to help wet
the leaves) works, but by killing the stems/leaves, which do grow back,
but the bulbs do eventually die with repeated application. It's
relatively harmless to other garden plants. I suppose oxalis is
susceptible to a mild alkali, as the leaves are quite delicate and
naturally acidic. I got rid of an oxalis patch using baking soda this
way - just leave a spray bottle with solution near the patch, and
occasionally zap any oxalis when you notice it. The leaves wilt/die in a
matter of hours.
A clue to the harmless nature of "Death to Oxalis" product is that it's
exempt from pesticide registration / active ingredient disclosure.

I'm not responsible for the chemical use on the garden , I didn't live
here then.It was done several months ago and according to Roundup the
chemicals are washed away and rendered inert after a few weeks.
It has a thick new layer on the top of compost and soil.

I just killed a Coprosma tree by painting glyphosate on the leaves of
Convolvulus that was climbing on the tree.Perhaps it rained overnight
and washed the glyphosate on to the tree leaves. I've also killed
patches of grass when painting oxalis in my lawn with glyphosate.
Baking soda doesn't seem to have much effect.

The problem with using glyphosate on lawn weeds is that grass is so
especially susceptible to it. A mere whiff seems to kill grass while
many weeds put up a stiff fight (marshmallow especially seems to be
hard to kill with it). Liquid nitrogen does wonders for flatweeds!

My sister made the mistake of spraying her roses with the wrong
sprayer, so they got glyphosate instead of the all-round rose spray.
With a lot of t.l.c. the plants have managed to survive, but they have
only produced few deformed flowers this season. We hope that there
might be some recovery by next season.

I can't remember the recommended dose / dilution for baking soda, but if
you check the label for "Death to Oxalis" in a shop, it should tell you.
A few drops of dishwash liquid also helps wet the leaves. On a warm
day, the leaves should start wilting within a couple of hours. If they
don't, then it's probably not oxalis.

Mix up 2 tablespoons baking soda, a squirt of dishwashing liquid, 500ml
water and squirt on oxalis area, preferably on a hot day. Repeat to
weaken re-growth until it disappears.


or:

Pour boiling water over the leaves. Continue to do this every time new
shoots come through


or:

Cut off the foliage, new leaves will appear and you will need to cut
these immediately, before they can get energy from the sun.

having gone through a similar exercise in spring, everything you noted is
familar. I have read that apparently when the oxalis is topped it sheds its
bulbs and those sprout. Successive prunings result in every smaller and
weaker plants as long as you keep on top of it.

I have tried all the different methods and still find that the best way is
to spend the time digging the stuff out,
your have to dig deep to make sure the the stems don't disconnect from the
bulbs.

You will still end up with plants from those that got away but they are
easier to manage.

Is there anything that eats Oxalis?

So far so good, but healthy soil is not dirt, it is a living ecosystem
which breaks down complex organic molecules into the simple compounds
which plants can use. In healthy soil the soil borne pathogenic
organisms which prey on plants are part of the food chain. Plants do
better in good healthy soil than they do where soil structure has been
destroyed by misuse of agricultural chemicals. A little balanced
fertilizer can be beneficial- more is not necessarily better. Spot
spraying can save a crop; blasting poisons everywhere is destructive,
expensive and in the end destroys the soil so that in effect you *are*
hydroponic farming so might as well go the whole way and do it properly
as you suggest. In my own personal experience, vegetables growing in good
healthy compost mulched soil have better flavour and keep longer than the
typical force feed supermarket fare.

thats basically the theory of organics or whatever name you wish to apply to
it, minimal or no use of sprays pesticides or synthetic fertilisers so you
don't disturb the soil food web. That is, you do everything you can to
maintain the soil condition & whatever is in it. There are weed killers
available that are plant oil based (pine oil etc) which dehydrate the plants
when sprayed on foliage. On a vege garden they are a better option than
round up if you want to avoid the possibility of "chemical residues bound up
in your soil". The debate over that last matter is ongoing. The plant oil
based sprays are still chemicals but seem to be a little kinder on the soil.
It's one option for people who want to be cautious around their vege garden
but will still kill weeds.
