How soon can i fertilize after spraying weed killer

If you’ve applied weed killer to your lawn, you’ll need to wait until the chemicals have had a chance to work before applying fertilizer. Depending on the type of weed killer you’ve used, this could be anywhere from a few hours to a few days. If you applied a glyphosate-based weed killer, you’ll need to wait at least 24 hours before fertilizing.

Glyphosate is a non-selective herbicide, which means it will kill any plant it comes in contact with – including your lawn grass. You don’t want to apply fertilizer immediately after spraying glyphosate, because it could damage or kill your grass. If you used a selective herbicide, such as something that only targets broadleaf weeds, you can usually apply fertilizer immediately after spraying.

However, it’s always a good idea to read the label of your weed killer to be sure. Some products may recommend waiting a certain amount of time before fertilizing.

Fertilizer or weed killer first

If you’re planning to fertilize your lawn this spring, you may be wondering whether it’s better to apply fertilizer or weed killer first. The answer depends on a few factors, including the type of fertilizer you’re using and the type of weeds you’re trying to control. If you’re using a granular fertilizer, it’s best to apply it before you spray for weeds.

That way, you can avoid getting the fertilizer on your weed plants, which would just be a waste of time and money.
