How and when to use lawn feeds and treatments
Lawn care is extremely important in the summer months, and pesky weeds can cause a number of issues.
However, according to the experts at icanlawn.com, there are easy ways to identify and get rid of them. They explained: “Two of the most common weed grasses are poa annua and couch grass.
“Equally thick and broad-leaved grasses, there are a few other distinguishing factors that will help you differentiate between the two.
“Poa annua is easily recognisable by its flowering grass blades and its (almost) radioactive green colour that will be a different shade to the rest of your lawn.
“Although more commonly found in lawns that aren’t well cared for, poa annua can appear in even the best looked after lawns as birds drop seeds into the soil and seeds can also lay dormant for years until given the opportunity to grow.

“Poa annua cannot be cured using a traditional weedkiller, so save your money on solutions that promise this.
“You should also never try to mow poa annua out of your lawn as this will cause its many seeds to spread and take over your lawn entirely.”
The “most effective” way to remove this weed from the lawn is to cut it at the roots diagonally with a pen knife or similar item, known as verti-cutting.
This works because the roots of the weed do not go underground, so cutting it on the surface will “weaken the roots and kill it”.

Couch grass is another trouble you may come across in your lawn, but isn’t quite as recognisable as poa annua with its easy-to-spot seed heads, according to the pros.
They said: “It also differs from poa annua in that its roots grow underground causing it to spread quickly.
“Couch grass grows in thick clusters and sports a rather crowded infrastructure of boisterous roots making it difficult to remove from your lawn.
“As couch grass roots go under the soil surface, you can’t use the verti-cutting method as used for poa annua.
“Your best hope of eradicating couch grass is to dig it out – ensuring not to leave any roots behind. Once removed, fill in the missing space with top soil and new seed.”
To prevent couch grass from returning, remove any sign of thicker grasses or weeds when they appear to stop them becoming a problem.
A healthy lawn which is well looked after will be in a better position to fend them off, according to the lawn experts.
