Posted on March 9th, 2016 by Prunin Arboriculture & Landscape

Proper soil aeration and lawn care offer many benefits. It is important to know when to perform it in order to provide the most benefits.

Taking care of your lawn is a must if you plan on having a lush, vibrant carpet of thick, green grass. Proper root growth is necessary for the blades of grass to gain all of the nutrients they need from the soil. This is the purpose of aeration and other lawn improvement techniques.

When Is the Best Time To Aerate?
The best time to aerate your lawn is the beginning of spring, shortly after the winter thaw. The longer hours of daylight and increasingly warmer temperatures help to bring the soil back to life after a cold winter of being dormant. Proper soil aeration and lawn care improvements made within the first few weeks of spring allows the warmer air to go deep into the soil and stimulate new root growth and the expansion of existing root systems. This encourages increased nutrient uptake and helps grass to come back to life much faster.

How to Aerate Your Lawn
Aeration is to create holes in the lawns surface, so as to let the stale carbon dioxide air out of the soil and the fresh oxygen rich air into the soil. The action of aerating also stimulates and encourages root growth. It is usually performed by passing over the lawn with a garden fork, digging it deep into the surface or with a mechanical aerator that presses steel tines of up to 125 mm into the lawn through to the root zone underneath. You should aerate your lawn at least once annually.

Why Is Aeration Important?
Aeration is important for several reasons. A few of the benefits include:

>> Improves drainage and prevents the ponding of water
>> Improves the exchange of gases between the soil and the environment
>> Improves the roots’ ability to take in nutrients from the soil
>> Allows water to infiltrate the soil and reach the deepest parts of the roots
>> Increases root depth
>> Relieves surface compaction and fluffs the soil
>> Encourages new root growth
>> Prevents thatch from building up below the soil
>> Increases the growth and activity of microbes in the soil

Keeping the soil viable is extremely important when it comes to sustained growth and the health of your lawn. Over the winter months, the soil can become hard packed and dry. This can make it harder for the roots and stems of your grass to get the nutrients they need to begin their spring growth cycle.
