Grass aeration is critical to lawn strength. Aerating the lawn adds air space for the earth permitting better water management and nutrients to reach the lawn roots. Much better absorption of water and nutrients results in a healthy, greener grass. Soil content is important. Lawns planted in clay soil require aeration more commonly than average soil lawns. Clay soil is extremely dense and tough to break up creating less air space. Aeration helps this problem. Low lying places also need stronger roots and ought to be aerated much more often than other spots of the lawn.
Grass aeration is required for high traffic foot locations and any low areas in the yard that keep water. These areas must be aerated often. For the majority of lawn attention with regular conditions, lawn aeration should be done just about once twelve months. Trouble areas can benefit from aerating more often, even as frequently as every month or two.
Three basic options exist to aerate lawns. Tine, core, and liquid aeration. Tine aeration calls for poking holes in the soil with a spike. This method is not recommend by professionals and can actually strengthen compaction for problem areas. Core aeration involves removing plugs of soil everywhere in the lawn which are around an inch in diameter. This method is used by others, but leaves holes all over the lawn which is very unsightly. Liquid lawn aeration may be the best method of the three. A liquid solution is applied and then watered into the lawn. The depth attained by liquid aeration is about 4 times deeper than core aeration. Liquid aeration is effective in the fact there are no holes in the lawn from core aeration or tines. It is also harmless to be used around sprinkler devices and base of trees.
