I'd like to get rid of all the grape hyacinth in a particular garden because: 1. The area surrounds a pond where I now have an electric raccoon fence and I can't have the new growth come up and short out the fence, and; 2. The area is planted heavily in black mondo grass and I hate the way it is completely choked out by the masses of grapes in the spring The problem is that the ground is saturated in the bulbs, they multiply incredibly fast! The only way I can think of is to pick off all the leaves as soon as they appear, over and over again. Will this eventually kill the bulbs? How many years do you think it will take? Any other suggestions?
