Trachelospermum asiaticum 'Tricolor' constant pruning is the usual control. Otherwise it's time to dig it out or use a brush-killer herbicide. http://almostedenplants.com/shopping/shopexd.asp?id=2982
Thanks...don't want to dig it up as it takes up a very large area in my front yard, but it is growing like something out of a sci-fi movie :)
It's too aggressive for a low maintenance landscape in a moist climate. In my drought stricken Texas climate it gets pruned twice a Summer at most.
I am in Georgia...what does pruning look like-how aggressive should I be with this plant when pruning?
Use a gas powered string trimmer as often as it needs it. Probably twice a month? Last pruning first of September so it has time to harden off before the first frost. http://ecx.images-amazon.com/images/I/51wM+JlSipL.jpg
I wouldn't do that til near the last frost date for your area. New growth (caused by pruning) too early is easily damaged by cold. http://mrec.ifas.ufl.edu/rcb/Jasmine/introduction.asp This link gives a possible control strategy. They say lime (high pH) is prone to weaken the plant. (Not in my experience) However it may slow growth which is what you want.
