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 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.
What Is Weed And Feed
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.
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, 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.
When we give lawns more food than they need, the excess fertilizers end up in the water because plants simply can’t absorb as much as we think they want.
Each year Americans apply an estimated 27 million pounds of weed ‘n feed to parks, cemeteries, home lawns and anywhere else mown grass is found. A mix of three “phenoxy herbicides” called 2,4-D, dicamba and mecoprop typically blended together into weed killers and weed ‘n feed products, they kill broadleaf plants such as dandelions while sparing grass.
3. Weed ‘n feed chemicals are easily tracked indoors.
For the health of our families, neighbors and our environment, herbicides use should be a measure of last resort.
Consumers should also realize that weed ‘n feed products may kill existing weeds, but do not prevent new weeds from growing. You can prevent new weeds from germinating by applying a pre-emergent herbicide during that first warm spell in spring and in the early fall. One of the best pre-emergents is corn gluten meal, a completely natural substance that also provides the benefits of fertilizing. Corn gluten meal is an organic alternative to weed ‘n feed.
Gary Fish, an environmental specialist at the Maine Board of Pesticide Control, who used to work with Chemlawn before it merged with Tru Green, believes the combined weed ‘n feed products, whether for pre-emergent fertilizer or for weeds, are unnecessary and harmful to the environment. Fish said weed ‘n feed products use 20 to 30 times more pesticide than is needed.
