Controlling lawn weeds
If you have a lot of weeds that have over wintered in your lawn, now is the time to think about controlling the weeds in your lawn.
You normally get two periods of weed activity in a normal year. The broadleaf weeds such as Cat's Ear, Plantains, Daisies, Dandelions to name a view of them will easily over winter in the turf. These need to be killed early on before the second turf weed season starts when you get the Red, White Clovers, Yellow Suckling Clovers and Trefoils appearing in around May and June time.
The selective turf herbicide is absorbed by the weeds and after a while, the weeds go into super growth, with their stems twisting and distorting. The weeds actually outgrow themselves and when their overall structure has literally had it, they die. Grasses do not have Cambium Cells so although they might absorb some of the chemical, it has no affect - if applied correctly in the first place!
One of the other early flowering turf weeds is Slender Speedwell, which exhibits tiny blue flowers. It is a challenge to kill it and early application of a selective herbicide is advisable. Once it has finished flowering, control is said to be too late. You can control it with Vitax Lawn Clear. More than one application may be required 6 weeks apart.For advice on total weed control products, you might find this article on Total Weed Control useful.
