The most common way to prevent weeds is by applying a
granular weed prevention product on the lawn in the early spring. The best time is before the weeds actually
germinate, generally about two weeks prior to the top soil reaching a temperature of 55° at daybreak. Make sure
that the product is apply just before rain or else make certain that you water it within a couple of days of
applying the product.
You should be aware that the product will not last the entire season. Most products will
begin to loose their efficiency within ten weeks if not less time. If your summer is rainy,
it can be even more of a problem. You will need to apply a second dose of weed prevention product about
eight weeks after the first application in order to ensure late season weed control. Make sure that you
apply the product at the right time in order to obtain the best results.
Once the weeds are already present in your lawn, a prevention product will not work. Also,
they are not effective at preventing perennial weeds. You will need to utilize a weed killer. The exact
type of product that you need to use will determine on the type of weed, such as whether it is grass in
nature or leafy in nature.
Weeds that are grassy tend to be thin and will stand upright. Leafy weeds feature wide
leaves with a main vein. You can use either a liquid or granular product. Most homeowners choose to use a
granular form that is mixed with fertilizer. This type of weed and seed application is extremely popular
and will work best when weeds are already established. They should be applied just after a rain or in the
morning when the lawn is still moist.
Grassy weeds can be somewhat difficult to kill due to the sheer fact that they are so
similar to grass. The products that are currently on the market for killing such weeds, like crabgrass,
should be applied early. It may take multiple applications for the product to kill the weeds completely.
Always make sure you check the label to determine whether the product is labeled for use on all warm
The good news is that most annual grassy type weeds will die when frost arrives. When it
comes to some types of weeds, such as low quality fescue, you may have to resort to spraying the affected
areas or simply digging them out.
Remember that the best time to kill weeds is to prevent them before they actually sprout.
Keep in mind that if you already have weeds you will need to apply a weed killer, which can be done at
any time during the growing season. Fall is an excellent time to attack perennial weeds because they try
to store energy within the root system before they go dormant during the winter.
Do take care when using a weed prevent or weed killer if you are planting new grass. Most
such products can stunt or even prevent new grass from growing. Be sure to always check the label to
determine when it is acceptable to plant grass when applying such products.
It is also important to make sure that you avoid using such products when there is a drought
or when your lawn is dormant. During such times you should refrain from using weed control products and
simply water your lawn. Do not worry about treating the weeds until the lawn has recovered.
