They look unsightly
They compete with grass

18. Weed control in turf This can be achieved in 3 ways
Cultural- making sure the conditions are best suited to grass growth and not weed growth e.g. dealing with compaction that might favour some weeds.
Physical- e.g. weeding by hand, or discouraging weeds by verti-cutting etc.
Chemical- by using a selective herbicide (weed killer) that is designed to kill weeds but leave grass unharmed.
