A plan weed and feed product to your lawn may seem like a perfect way to kill two birds with one stone. Not only are you can to get eliminate irritating weeds however the chemical contained within the product additionally can facilitate the grass to thrive. Weed and feed products aren’t ideal for all situations though and may cause some problems if you plan to receive the lawn soon after their application.
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.
In order to activate, most weed and feed products are granular and should be applied to moist grass. Mow 2 – 4 days in advance and use the weed and feed products for best results, without additional rain for at least 48 hours. After application, do not mow the treated grass for at least 7 days to allow the herbicide time to work.
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.
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.
If you must sow grass seed after applying weed and feed, wait at least four to six weeks before doing so to ensure the herbicide won’t prevent the seeds from sprouting.
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.
Different grass varieties thrive when planted at different times of the year. If you have a specific variety in mind find out the most favorable to sow it to ensure the best results.
