Four months later and I am digging out the kikuyu on chook site five.The big effort on the first four has been proved very worthwhile, as was leaving the sites bare for a while to see what was resprouting. Very little kikuyu has regrown and can easily be removed. Invasion from the edges is something of a problem but not too bad if kept an eye on for removal of runners before they get a grip! A much bigger problem is heliotrope. I am digging it out after it resprouts after winter but there are thousands of seeds germinating on every site. I am scratching them up regularly with a rake but does anyone know how to control this weed which is harmful to the livers of livestock and chooks? DPI has done some trials with a beetle in this area and there are a few beetles around but not enough to make a real impact on the foliage.I’m guessing that the beetles only eat the foliage anyway because heliotrope is very deep and strong rooted.
Bumping this thread. There are some great ideas here. We have a massive kikuyu problem here. It’s invading from all over. I’ve had some success making pathways around a garden area using newspaper topped with gum tree mulch, but I still have to battle the advances of the ki regularly. However, inside the gardens I had used the chook dome & then planted it out heavily with veg & mulched heavily with pea straw. It seems easier to pick out the small amounts that grow through.
However, this last season the kikuyu has loved the wet summer & is absolutely rampant. We have about an acre of it that I want to get rid of. Is there anything I can mass plant into it that will take it over & knock it back?
Ma, your biodynamic principle of using the weed to kill the weed fascinates me – how’s that working for you?
I have to say I agree with Bill we had to spray our paths last weekend and in the past it is the only thing that kills it other than boiling water but on 4 acres I ain’t filling that many kettles. I do pull it out of the veg garden though as we don’t spray there. The only real thing that works other than spraying is good ol’ elbow grease and turning the soil over to find the runners.
cover it up with something, black plastic, tarp, watertank, anything will do, and then leave it. It will be lovely worm castings in about 4 to 6 months. Takes a while but if you’ve got the time it beats cutting turf.
