I have a border in my garden that was full of grape hyacinths. My wife and I have spent many hours trying to get rid of them but they keep growing by the hour. Is there anything I can put on them to remove completely?

I am afraid that they can only be eradicated by digging up the plants or using a broad spectrum herbicide, which would kill everything in the area. You can minimize their spread (so you don't feel you are fighting a losing battle) by removing the foliage and any seed pods. This will keep seeds from being spread and weaken the bulbs so they cant produce bulblets.
