reasonable level. At least its easy to pull up - even if the bulb rarely
comes with the root."

I may try this combined approach too along with seeding in the bunchgrasses and
forbs I want in the steepest parts of the land.

In my experience lack of cultivation delays the spread of this Oxalis but does
nothing to get rid of what is already there. It multiplies by offsets
rapidly though it doesn't set seed supposedly. Do we know that the sterile
form was the only one ever introduced???? Are there fertile forms of this
Oxalis in SA?
