Three weeks of my being sick. Several weeks of showers and warm weather. Perfect growing weather for kikuyu grass. And it's grown like Jack's beanstalk! It's past my knees in the vegie patch and trying to swamp everything!
I have tried to stop it in the past with a lemon grass hedge around the perimeter of the vegie patch, and a path just inside that, but the lemon grass keeps dying, presumably because it's been strangled by the kikuyu.
Secondly, the only thing that kills the stuff is glyphosate, but that doesn't work in a well-watered area -- so I can either spray the kikuyu or I can keep my vegies watered, but not both. The spray drift is another issue, of course.
In one spot, I laid a piece of old corrugated iron on the ground to kill what was underneath. It does seem to have worked, but that's only two square meters or so, and I've killed everything else underneath as well. Nonetheless, I will plant the edge of this area up with lemon grass and see if it survives.
Any other ideas?
