Root Zone

Definition - What does Root Zone mean?

The root zone is the area of oxygen and soil surrounding the roots of a plant. Understanding and locating the root zone is a crucial part of gardening. As roots are the starting point of a plant’s vascular system, knowing the root zone of the plant will help the gardener cater to the needs of the plant in a more efficient manner.

A plant can only be healthy if it has a healthy root zone. Plants that have deep roots have a deeper root zone and depend more on groundwater. Knowing the drip line area of the plant's root zone will also help to efficiently water plants in a drought.

Some gardeners might forget or overlook the root zone when fertilizing plants. However, the root zone is the most important part of the plant that requires fertilizing. Deep root feeding can encourage the growth of fibrous roots and can also protect the plant from receiving nutrients that have overheated or dehydrated.

It is also important for growers to maintain a healthy temperature in the root zone and maintain the health of the soil surrounding the root zone. Weak root zones resulting from clay soil, extremely high or low temperatures, and improper watering will lessen the plant's ability to absorb water and nutrients properly.
