How to Build an Effective Root System

Roots are instrumental in supplying plants with water and nutrients. You can easily trace the root of a problem by looking at the top of a plant. While a thriving plant will have healthy roots, a stunted plant is most likely suffering from a poor root system. If your grass is unhealthy, you can promote root growth and improve the quality of your lawn by following a few guidelines.

Factors Affecting Root System Development

There are several factors that affect root system development, including:

  • Air movement
  • Water
  • Thatch
  • Microbial and insect activity
  • Soil compaction
  • Fertilizer
  • Light
  • Mowing height

How to Grow a Healthy and Effective Root System

To ensure a healthy and effective root system, keep the following in mind:

Mow the grass at the tallest height recommended for your grass type- Since heights vary between grass types, it's helpful to determine your lawn's grass type before mowing. This is due to the fact that grass roots grow directly proportional to the top of the plant. For example, shorter plants possess shallower roots.

Water the lawn deeply and infrequently- Frequent, shallow watering of one's lawn results in roots not having to grow and reach down into the subsoil for water. For this reason, it's better to water one's lawn less frequently and more deeply because this promotes better root growth.

Healthy grass has healthy roots- Grass typically doesn't grow well in shade. Therefore, it's suggested that you plant grass in areas flooded by sunlight. Thatch can also impair root growth. This type of buildup is a common lawn care problem. Rather than grow in the soil, thatch causes roots to grow on top of it. Grass is then more likely to endure damage caused by environmental factors, pests, and diseases.

Keep the soil from being compacted- When soil is tightly compacted, it's more difficult for nutrients to reach surrounding roots. To prevent this from happening, refrain from walking on grass after heavy rainfall. You can also aerate and rake a thin layer of sifted compost over the aerated grass.

Encourage a healthy earthworm population and soil microbe population- Soil is alive with organisms like bacteria, fungi, worms, and insects. These organisms help create pores in the soil where air and water travel. They also break down organic matter into smaller particles so that plants can make use of them. To boost overall health in these organisms, avoid excessive use of fertilizer and pesticides.

Use balanced fertilizers- Fertilizers that have more nitrogen than phosphorous and potassium encourage top growth rather than root growth. Instead of strengthening grass, top growth causes it to weaken. Limiting the amount of chemical fertilizer used on one's lawn provides roots with a better chance for growth.

Building and maintaining an effective root system can be a lengthy process. For this reason, you may want to seek assistance from a lawn care professional.
