Lawn (Selective) Weedkillers
The thick, green beauty of a lawn is marred by the presence of weeds. The most common culprits include dandelions, daisies, white clover and plantains. Controlling them is relatively easy - one application of a lawn weedkiller treatment should kill them if it is applied at the right time. There are a host of other plants with smaller leaves that are not so easily controlled when they infest a lawn. These include lesser trefoil (yellow suckling clover), black medick (a small leaved clover) common mouse-ear chickweed, yarrow, parsley-piert and the blue-flowered speedwell.
If left untreated all these lawn weeds will spread to fight the grass for space, food and light, gradually ruining the look of the lawn. To kill the weeds without damaging the grass choose a selective weedkiller detailed below that is recommended for lawn use or choose a granular lawn treatment that states that it will kill lawn weeds detailed in the Lawn Care section of this web site.
Verdone Extra
Specially formulated Selective weedkiller for the ‘broad-leaved’ weeds that invade lawns and ‘suffocate’ the grass. Use on all established lawns and grassy areas in late Spring and early Summer. Weeds wilt, turn brown and die within 4-6 weeks. This removes the competition and allows grass to thrive and spread. Can be used on new lawns over 2 months old.
Granular lawn treatments that include weedkillers will quickly and easily get rid of the common broad-leaved weeds, but may leave the small leaved varieties damaged, but not defeated. With these difficult-to-control weeds you need to use a liquid lawn weedkiller to get the most effective control. Use the concentrate Verdone Extra diluted in a pressure sprayer or Verdone Extra Ready To Use. Applied thoroughly as a fine spray, these products will ensure that each and every leaf can be treated and receives a good dose of weedkiller.
Getting the best lawn weeding results
Make sure the weeds are growing strongly
Use during late Spring and Summer when the grass and weeds are actively growing. The soil should be moist and the weather should be warm. If necessary, water the lawn a day or two before treatment to ensure the weed is moving sap around the plant.
Apply between mowings
Do not mow the lawn for at least 3 days before treatment. In this time a good leaf cover should have been created and this will give a good area of weed leaves to treat.
Apply on a dry day
Choose a day when it doesn’t threaten rain. The longer the weedkiller remains on the leaf undissolved the better.
Wait for the weedkiller to work
Don’t mow the grass for at least 3 days after treatment. This gives the weed sufficient time to move the active ingredients down to the roots for the best kill. Over the next few weeks the weeds will twist and turn and gradually die off. Don’t worry if you see a sudden burst of upward leaf growth immediately after treatment. This is quite normal and indicates the weedkiller is working.
Beware!
Note that not all weedkillers are selective - products containing glyphosate, and other general purpose weedkillers such as Weedol Gun! and Pathclear Gun! Season-Long will kill grasses as well as broadleaved weeds. Check that the weedkiller you choose is recommended for use on lawns.
