Our lawn program includes weed control and fertilizer because they both play an important part in ridding your lawn of weeds. The weed control kills off existing weeds, while the fertilize helps thicken the lawn to naturally limit reproduction of weeds.
We highly recommend both weed control and fertilizer but understand that may not be what you are looking to achieve with your lawn at this time. We will put together a plan for you that includes weed control applications only, but we do not offer our weed-free guarantee for these applications.
The first thing we need to do is make sure it is crabgrass. If it is early in the year and the soil temperature is less than 55 degrees crabgrass will not germinate. Sending us a picture will help identify what type of grass you have, and if it needs to be eliminated from your lawn.
The best way to control crabgrass is to apply a pre-emergent so it does not get a chance to start growing. If it has already established itself there are post emergent treatments we can apply to kill it. If you have a 7-application lawn care program or the Extender program, these treatments are provided at no cost to you.
Our liquid weed controls are the most effective available. Weeds begin to curl and disappear in 2-3 days, but it may take up to two weeks before they are completely gone. Unusually hot weather, a heavy rain after your treatment, or mowing immediately after treatment can reduce control. The good news is that as a Lush Lawn customer with a 7-treatment program, you can simply call us and we will retreat your lawn, at no extra cost to you! If the issue persists, please let us know and we will be glad to investigate additional steps that can be taken to help get your lawn in top shape.
This is a great question, and we wish we could offer a service like that. But unfortunately, no single chemical (or combination of chemicals) is available to control all weeds, at one time, in one spraying. There are two major weed groups that grow in your lawn throughout the year: broadleaf weeds (clover, dandelions) that grow in cool temperatures, and grassy weeds (crabgrass) that grow during warm temperatures. Each weed group has specific chemicals that are used for post-emergent control. These chemicals can only work on these weeds within a certain temperature range. For example, broadleaf weeds can be controlled if temperatures stay above 32°F. The cooler the temps the slower it takes for the results – usually 2-3 weeks. On the other hand, grassy weeds require 80°F days and 70°F nights for control. If it does not reach this range, you will not see good results.
If the weeds do not die after the number of days required for results, we will provide a free re-spray if the request is within 14 days of your last regularly scheduled treatment. For any re-spray requests made after 14 days of your latest application; the next treatment will be applied instead of a service call at your regular treatment cost. You can request a service call on our website, via email, or by telephone.
Weed control is dependent on the temperature. A general rule of thumb is the colder the evening temperature the longer it takes for weeds to die.
Cold evening temperatures (rounds 1, 2, 3, and 7) – may take 14 to 21 days to see results.
Warm evening temperatures (rounds 4, 5, and 6) – should show results within 7-10 days.
