What is Clover?
Clover is a very common weed of lawns. Clover has leaves with three leaflets, and creeping stems that set roots at whatever point they touch the ground. Flowers are white or pink (Trifolium repens, Trifolium fragiferam). Clover, with white flowers, is a member of the pea family, Fabaceae. This means clovers can fix nitrogen from the air and therefore they favour poorly fertilised lawns. One method of preventing clovers from taking hold is to make sure your lawn is growing strongly and is well fertilised during the warmer, growing months.
Some home owners grow a complete lawn using clover. Never use selective herbicides on clover lawns.
