Can you please help. I work at a local hospice and am getting a majore
problem with oxalis taking over in the bedding schemes every year. The
only way i can see to control it is to replace all the soil in the beds
but that would be to costly to do as we are a charity and the money is
better spent on patient care.
Is anyone else had this problem and how did you sort it out. Is there
anything i can spray to control the problem..
Thanks in advance for any help



Oxalis is a horrible weed to try to control.
Digging it up, unless you get the largish whie seed at the base of each
stem, is futile because the seed will soon send up another stem.
Pulling usually gets just the leaf and stem.

When those pretty little flowers form, seed soon follows and the plant
will "spit" the seed for a wide radius (10 feet or more.)

Any kind of plant in the vicinity that you may try to transplant will
carry the oxalis seeds with it and infect someone else's garden.

Even replacing the soil won't do the job unless you dig down far enough
to remove all the seeds, If not, the plant will soon recover and sprout
again.

Do Google "oxalis control" to see what kind of chemicals are available
in your area. It will probably take an entire season of applications
to rid the site. We have been struggling with it for years, both in our
flower and vegetable garden and in the lawn.
