What is the procedure for aerating your lawn and does this help with weeds and clovers?

The soil under your lawn can become compacted from foot traffic, and compacted soil excludes air (which roots need). You can fix compacted lawns by aerating every 2-3 years in either the spring or the fall. If you rent a power aerator, it will dislodge plugs of soil. Leave the plugs on the lawn (they'll decompose and break down in the rain). After aerating, spread a thin layer of sand or organic mulch over the top of the lawn and then water deeply.

Aerating doesn't eliminate weeds and clover, but will promote a lush, healthy lawn which should crowd out weeds. If your lawn is less than 3 years old I wouldn't aerate, but instead get rid of the weeds and then put the lawn on a regular maintenance schedule of mowing frequently, watering deeply (one inch per week) and feeding 4 times a year (April, June, September and early December).

Hope this answers your question!
