[Fwd: Oxalis]

Hi Shirley:
Certain Oxalises can become terrible pests (pest-caprae,
corniculata, articulata, etc.). Yes they may set seed although this is not
so common as in most other plants except in their native habitats. Lots of
offsets of many sizes are produced by the mother bulbs and when one removes
the big clumps it is common that tiny offsets fell and are spread around.
Along this, it is better to place the removed clumps in buckets or bags and
not carrying them around in the hands. Another way of propagation shared by
both valued and weedy kinds alike is the production of runners that spread
new bulbils around. This is another source for Oxalis contamination.
Haven't you friend tried spraying the clumps with broad leaved herbicide?
This is usually pretty effective and a single application will make it. The
plants must be in full growth and warm weather is desirable.
Regards
Alberto-
