Fast-growing broad-leaved weeds in a lawn will soon choke out your carefully manicured grass and leave you with unsightly clumps instead. Knowing the right way to apply your weed killer for maximum economy and results will make your lawn maintenance easier and leave you time to enjoy the lawn you’ve worked so hard on.
What type of weed killer should I use?
Every nursery and home depot will carry a comprehensive range of lawn weed treatments. We recommend buying a liquid concentrate, as it gives you better control, will allow you to mix it easily in a lawn sprayer and will prove more economical, especially for big lawns. Read your particular products instructions carefully and follow them, mixing up a quantity suitable for the job. Make sure the pump spray head and nozzle are firmly attached and if you’re using a pressurized sprayer (far easier on you and available cheaply at most garden centers) pump it up ready for use. There are also granular weed killing options, although these are less directed and you may not want to use them if you have children or pets. A firm watering before and 48 hours afterwards is recommended with granular weed killers.
How to spray?
Make sure you’re not planning to spray weeds on a day where there’s a high wind. It would be too easy for fine spray to drift onto desirable plants near the lawn. Bear in mind that lawn weed control is a contact poison- so it will kill through any leaf surfaces that it comes into contact with. For undesirable plants, it’s vital that you get good coverage- but equally you don’t let drift carry it to you prize begonias! Also bear in mind that weed killers for lawns are designed to target broad-leafed weeds, so the fine leaved weeds may be harder to kill off, and with the grass-mimicking weeds you may have to resort to using a manual weeder to get them out of the soil.
Because of the fact it works by contact, you are going to want to leave your grass uncut for a good few days before weeding to maximize the surface area of the weeds. You will want to leave if for a couple of days after spraying as well to allow the poison to work. You may also want to keep children and pets off the lawn for a day after spraying for safety.
As you’re spraying your lawn, be sure to thoroughly coat the obvious ones first. When you’re sure you’ve got all the obvious ones, go back over the lawn in general. One good method for keeping track of where you are is to tackle the edges before finishing off with the center of the lawn.
Keep it up
Once you’ve done the preliminary spraying, it’s a good idea to set up a regular schedule of de-weeding every eight weeks or so through the growing season.
With modern weeding technology and a few easy tips, keeping your lawn weed-free and ready for that summer barbeque is as easy as one, two, spray!
