Hi all,

In my not so perfect lawn I have two patches of twitch grass (very broad leaved) which are taking over and increasing in size every year.

Is it possible to sprinkle weed killer on the affected areas and at the same time sow some normal lawn grass seed to replenish the bad areas?

Hi,
You can sow grass seeds after 3 days in areas where weed killer is applied. There is no issue in sowing seeds in other unaffected areas.
