Post-emergent products are designed to kill weeds that have already sprung up. They are broken up into two categories, selective and nonselective. Selective herbicides, will only affect the target weed listed. Non-selective herbicides will kill anything it comes in contact with.

Apply non-selective herbicides to only those weeds or foliage you wish to eliminate, being careful to avoid desirable plants. Most selective herbicides can be broadcast over the area that is infested with the target weed.

Post emergents come  in a liquid form to be applied with a sprayer and a granule form to be applied using a spreader. If using a liquid form, spray it directly onto the weeds you are trying to get rid of. For best results, do not mow your lawn before the application. This will allow the product to get maximum contact with the root of the weed by transferring down through the plant from the foliage.

If using a granular form, apply the herbicide to the lawn using a spreader. Then activate it using water sprinklers or a garden hose.

Most post emergents need to be applied more than once throughout the growing season. A final application is recommended to be put down in the fall, between August and October, and when soil temperatures are 55 plus degrees. This will help prevent weeds from spreading new seeds and sprouting up in the spring. Always refer to the product label for specific application instructions.
