The Importance of Soil Aeration In The Garden

When you’re busy monitoring pH levels, adding fertilizer and performing other basic maintenance to your garden, it’s easy to forget about something as simple as soil aeration. And while it may not have as much influence in a plant’s health as some of the previously mentioned elements, it will still play a role in their overall growth and development. Allowing your soil to remain dense restricts your plant’s from the elements it needs to grow, which in turn results in smaller, less healthy plants.

The week, we’re going to discuss some of the benefits of having aerated soil in your garden. The truth is that most gardeners greatly underestimate the importance of soil aeration. It’s not until they notice their plants suffering from health defects when they begin to suspect something is wrong with their soil.

Allows For Root Expansion

Arguably, one of the greatest benefits of soil aeration is the simple fact that it allows for greater root expansion. For instance, take a look at the the illustration below. It shows a plant with half of it roots grown into a well-aerated soil and the other half grown into a dense portion of soil with little-to-no aeration.

When soil is packed tightly together, a plant’s roots are unable to expand. Rather than growing outwards where they can create elaborate spiderweb-like designs, they remain bunched up directly underneath the plant.

Of course, this may lead to a range of problems, some of which includes the following:
•Lack of nutrition
•Plant instability (floors or severe storms may knock the plant down more easily)
•Susceptible to disease and illness
•Failure to bloom
