Why Does the Weed and Feed Fertilizer I bought not work?
Although it is not time here in North Texas to put down a weed and feed or a broad-leaf weed killer,(late feb to early march) we will continue to get this question at least a 1000 times this spring. Lets answer the question before you have to ask it any more. Broad-leaf herbicides are only effectively when low temperature are consistently above 55 degrees (when plants are actively growing).
Weed and Feeds are good for existing weeds not to prevent new weeds.Herbicides within a weed and feed product are absorbed through the leaves of the weed, therefore we recommend that you don't put it down on a freshly cut yard because you just cut off the leaf of the weed and now it has nothing to stick to.
Rather, we suggest you wait 5 to 7 days after cutting to apply. Because a herbicide has to stick to a weed in order to kill it then it is recommended to put it down in the morning when there is dew on the ground as this will help the Weed and Feed Fertilizer stick much better than a dry weed.
So I did all of this but it still didn't work ?
It is very rare that the proper timing for both herbicides and lawn fertilization sold to a consumer as a weed and feed product actually coincide, especially in North Texas. If you do not have weeds visible in your yard and are using a weed and feed you are wasting it. Also did you water ? 90% of homeowners forget the most crucial step to applying a weed and feed fertilizer which is to water it in.
If all of this is still confusing to you hire professional lawn applicator for the best results
