The weedy grass which invades many home lawns every winter is Wintergress, Poa annua is the scientific name for wintergrass.
This weedy grass has bright green leaves which are soft and produce multiple seed heads, it’s root system is also a massive problem due to it’s spider-web like masses of fine white roots which quickly crowd out the soil profile of the lawn, which in turn leaves less room for lawn roots to exist in the same space. This problem is not only evident in the Winter time when we see winter grass, but also throughout the entire year.
Wintergrass is a real problem when is comes to lawn mowing too. During lawn mowing the winter grass will often slash and look terrible afterwards. So now we know we have a problem that needs to be addressed, lets address it, and kill wintergrass!
Wintergrass can only be killed by a special herbicide which has been specifically made to kill wintergrass. The poison is mixed up in a watering can and to manufacturers specifications and then applied to the lawn. After application, the weed killer is then watered into the lawn so that it can reach down into the root zone of the weeds.
Wintergrass killer acts by poisoning the roots of the weed!
Allow 3-6 weeks for the Wintergrass to die off after applying the herbicide.
Timing is critical when applying this poison. It must be applied as early as possible in the season when wintergrass in a problem – which is Winter. The poison can also be applied before the wintergrass is even seen. So 2-4 weeks before winter begins is one of the very best times to apply this poison as the seedlings are just beginning to germinate and are at their weakest, and so are most easily killed.
Once the wintergrass becomes very mature in the later part of winter, it will be almost impossible to kill the weeds because they can more easily resist these herbicides. So be sure to apply as early as possible.
