weed and feed vs grass seed

Weed and feed products work by preventing new growth, effectively stopping weed seeds from sprouting and newly sprouted wheat from flourishing. However, the herbicides used are insufficient to target weeds only; grass grains and any new grass growth are the same.

If you must sow grass seed after applying weed and feed, wait for at least four to six weeks before doing so to ensure the herbicide won’t prevent the seeds from sprouting. Prepare seedbeds with the help of a rake which is one of the important garden tools that every gardener should have. It helps the seeds to have proper contact with the ground and prevents any bare patches.


Ideally, you should plant seeds well enough before frost in the autumn so that the new grass will grow for several weeks before sleep. You can also sow grass seed in the early spring, though if you do so you should hold off on applying weaving feet for at least four to eight weeks to ensure it doesn’t damage the young grass.

Weed and feed products, as the name implies, contain both a fertilizer and a herbicide to control weeds while feeding the surrounding grass. If the lawn has grass that is already established, this works well. The product should ideally be applied just a couple of weeks after the final frost when grass and weeds grow visibly because it is not effective for sleeping weeds. Apply it periodically throughout the rest of the year as well to keep weeds under control.

It can take up to four weeks for the herbicide effective to fade, so sowing grass soon after applying weed and feed is likely futile because new grass won’t be able to grow.

Canopy Lawn Care takes a comprehensive approach to our weed control program. Our lawn care pros apply split applications for pre-emergent weed control. The goal of pre-emergent weed control is to prevent the germination of weeds so they never have the opportunity to protrude through the soil. For maximum effectiveness, Canopy performs this service in two different applications.

Weed and feed is a term that has been created to describe the combination of weed control and fertilizer. These are two separate lawn care services that are not always performed at the same time. In fact, buyers should beware of purchasing products labeled “weed and feed” because depending on your grass type, it may not be best to apply both a weed control and a lawn fertilizer at one time. When it comes to the overall health of your lawn, the best approach for weed control and fertilizer application is to apply each product during the optimal season.

Weed Control

Pre-emergent weed controls should be applied during the right season for the grass type that you intend to treat. For cool-season grasses, like Fescue, pre-emergent weed control should be applied at the beginning of spring and then again approximately one month following the first application. In the southeast, the first application is usually applied in February and then again in March. Warm-season grasses, like Bermuda, receive their split applications in February and then again in September. These events line up with the grass growth cycle, so the dates will vary depending on the climate zone.

Fertilization is extremely beneficial for lawns. There are many different kinds of lawn fertilizer, but most common varieties of fertilizer contain some level of both nitrogen and phosphorus. When shopping for a fertilization product, be sure to ask a lawn care professional what blend might be best for your grass type. Organic fertilizer is also available and typically contains nitrogen and phosphorus naturally. However, organic fertilizer can also contain weed seeds, so be aware of that when you are spreading!

Canopy Lawn Care Pros spread granular fertilizer blends using a fertilizer spread. These blends are designed for grass type they will be applied to. These fertilizers feed your lawn when they are absorbed into the soil.
