When To Apply Weed Killer

(Last Updated On: June 18, 2022)

Weed killers are an important tool in the fight against unwanted vegetation. But, when is the best time to apply them? The answer to that question depends on a number of factors, including the type of weed, the time of year, and the stage of growth.

Here are a few general guidelines to help you determine when to apply weed killer.

The time of year when you should apply weed killer depends on the type of weed killer you are using. If you are using a pre-emergent weed killer, you should apply it in early spring, before the weeds start to emerge. If you are using a post-emergent weed killer, you should apply it in late spring or early summer, after the weeds have started to grow.
