There are plenty of people who would envy you!

Aside from pulling out plants as they appear, the best way to get rid of dill is to prevent it from flowering - hence producing seeds, which can spread far and wide. So - cut off the flowers as they appear.

I'm one of those people who envy you. I live in east TN where its been unsually hot and dry, and all my dill croaked despite my every attempt to save it. Just too hot I was told by another reader. You must live in a cooler climate where too much heat is not a problem. Maybe you can dig up some of the extra dill and give it someone canning dill pickles. They might welcome the idea of growing their own dill for canning purposes. Good luck,
