Killing Weeds

Question

We have huge weeds that have alot of seeds that fall of if you try to pull. Is there a weed killer that will kill both the weed and its seeds?

Answer 1

Once a weed produces seed it is at the end of its life cycle and even weed killers do not work well on the weed at this stage. Weed killers work best when a weed is young and growing vigorously. Once it goes to seed, you will need to use a pre-emergent weed killer to prevent the seeds from growing.
