Deep Root Fertilization 101

Ornamental trees planted in your landscape may not have access to the necessary nutrients. To ensure they get the nutrients they would in nature, turn to deep root fertilization. Read on to learn more about how deep root fertilization can help your trees realize their full potential.

What is Deep Root Fertilization?

Deep root fertilization is a process that involves fertilizing tree roots found 8-12” deep in the soil. By utilizing feeding equipment, slow-release fertilizer can be injected with enough pressure to reach this root zone. Surface fertilization may suffice for turfgrass and small shrubs, but for roots that run deep, this approach is recommended.

Signs Your Trees Need Deep Root Fertilization

Fertilizing your trees shouldn’t be an afterthought in your maintenance plan. Ornamental trees may need deep root fertilization treatment if they show any of the following signs:

• Dry brown spots on leaves
• Thinning or dying branch tips
• Unusually slow annual growth
• Poor vigor

One to two annual applications, either in the late winter or early spring, will feed a tree throughout its growing season. Performing these treatments during the summer months may distress your trees, delaying the benefits of the fertilizer or even putting them at risk.

The Benefits of Deep Root Fertilization

While deep root fertilization helps to sustain a tree’s overall health, this long-chain fertilizer isn’t a growth stimulant. Rather, with the proper application cadence and technique, deep root fertilization benefits your trees in a variety of ways:

• Provides the soil with nutrients
• Prevents damage from winter weather
• Builds resistance to pests and disease
• Produces a healthier plant
