Tree and Shrub Care: 5 Essential Steps for Healthy Trees and Shrubs

• Tree and shrub care includes planting, watering, mulching, feeding and pest protection.
• Plant trees and shrubs in spring or fall to reduce stress and support root growth.
• Apply up to 3 inches of mulch around tree base to protect roots and retain moisture.
• Water trees and shrubs deeply and less often to encourage stronger root growth.
• Check trees and shrubs regularly for pests and other signs of damage

Healthy, thriving landscapes don’t just happen. They’re the result of thoughtful, ongoing tree and shrub care that supports growth from the roots up. Whether you’re introducing new trees or protecting established shrubs, the right maintenance plan helps your landscape stay vibrant and resilient. This guide outlines five essential steps to successful tree and shrub care, from planting and feeding to long-term protection.

Mulch is a key part of tree and shrub care, protecting roots, retaining moisture and keeping your landscape looking its best.

Why Mulch Matters

A properly applied layer of mulch:

• Helps soil retain moisture.
• Regulates soil temperature.
• Suppresses weed growth.
• Improves soil structure as it breaks down.
• Protects roots from temperature extremes.

Organic shredded mulch also increases the level of organic matter in the soil over time, supporting healthier root systems.

Proper Mulch Application

Mulch should be applied around the base of trees and shrubs to a depth of no more than three inches. Keep mulch pulled back a few inches from the trunk to prevent moisture buildup and disease, and refresh mulch annually to maintain its benefits.

In cold climates, mulch also plays an important role in winter protection by insulating roots from freeze and thaw cycles. This added insulation supports root health and reduces cold-weather stress. 

Even healthy trees and shrubs can be affected by pests and diseases. Proactive protection is essential to keep plants strong, vibrant and resilient.

Common Threats to Landscape Plants

Trees and shrubs can be affected by a wide range of pests and diseases depending on the local climate and plant type. Left untreated, these issues can weaken plants, reduce growth and lead to long-term damage.

Targeted Treatment and Preventive Care

TruGreen’s TruShrub program helps identify threats early and deliver the right treatment. Key strategies include:

• Horticultural oil to control insects before damage occurs.
• Timely interventions to reduce pest pressure and protect plant health.
• Preventive care to maintain consistent tree and shrub health year-round.

Early detection and proper treatment help avoid costly damage and keep your landscape thriving.

What is tree and shrub care?

Tree and shrub care refers to the professional maintenance of trees and shrubs through proper planting, watering, mulching, fertilization and protection from pests and diseases. It’s designed to promote healthy growth, reduce stress and pest damage, and extend the life of landscape plants.

How often should you fertilize trees and shrubs?

Most trees and shrubs benefit from professional fertilization several times per year, depending on soil conditions, plant type and overall health. A TruGreen specialist can determine the optimal schedule based on your specific landscape.

What are the best ways to protect trees from insects?

The best protection includes routine inspections, early detection and targeted treatments such as horticultural oils or specialized insect control products. Preventive care is more effective than treating advanced infestations.
