Core aeration for your lawn is a very important cultural practice. A lot of people pay for a lawn service company to come out and perform core aeration but do not even know why they are just told the lawn needs it. This is not a bad thing because most lawns could benefit from core aeration, but you should really understand what the befit to your lawn is so that you can appreciate your investment and realize it’s true value.
What Core Aeration Does
- Helps decompose thatch by increasing microbiological activity
- Improves rooting
- Increase nutrient, oxygen and water movement into the soil
- Helps prevent fertilizer and pesticide run off
- Enhances penetration of irrigation and rainfall
Well that seems impressive but how does it help the grass. When you walk, play, or drive on the lawn the soil below becomes compacted even mowing the lawn can contribute. By aerating your lawn you are actually open up air spaces in the soil and helping to relieve this compaction. Compacted soil makes it hard for the roots to penetrate very deep in the soil and undoes what the heavy and thaw cycle does.
The plugs from aeration pulls out bits of thatch and soil and throws it on the lawn as the soil breaks apart it spreads beneficial microorganisms on top of the thatch so they can begin breaking them down.Ã‚ By helping to eliminate thatch you are making the lawn more healthy.
The holes the plugs leave behind actually serves a couple of purposes. The roots from the grass will grow into theses air spaces making the grass more healthy. Plant roots do not actually grow in the soil but the airspace between the soil particles. In compacted soil there is less air space so the roots do not grow as well.Ã‚ The holes also act like a giant sponge to allow the water to run down into the soil instead of over the top and out into the gutter. After a core aeration the actually surface area of the lawn that can absorb water, fertilizer, and pesticides is actually increased to five times it’s normal surface area.
Finally by opening up holes in the soil you are helping gases below the surface escape more readily and allowing oxygen to reach the root zone. This will stimulate new root growth and make for a healthy lawn. Remember all the nutrients and moisture come from the root of the plant. To have a healthy grass plant you need healthy roots.
Having a healthy lawn is not only a source of pride but it helps the environment as well by giving off moisture, cleaning gases from the air, and helping to retain the soils surface.
