How to Keep Large Trees in Your Backyard Healthy


Large trees in your backyard not only add beauty and shade to your outdoor space but also provide numerous environmental benefits. Keeping these majestic trees healthy is essential for their longevity and continued enjoyment. 

This article will explore practical tips and guidelines to help you maintain the health of large trees in your backyard, ensuring they thrive for years to come.

Regular Inspections

Regularly inspecting your large trees is the first step in maintaining their health. Look for signs of damage, disease, or pests such as dead branches, cracks in the trunk, fungal growth, or insect infestations. 

Early detection of these issues allows for timely intervention, preventing further damage and promoting tree health. If you notice any concerning signs, consult a certified arborist for professional advice and assistance.

Suitable Watering

Large trees require regular watering to stay healthy, especially in times of dry weather or drought. Water the tree’s root zone thoroughly and slowly to ensure that the water fully penetrates the soil. 

As frequent shallow watering might result in shallow root growth, avoid it. If you want to provide water directly to the root zone, think about employing a drip irrigation system or soaker hoses. 

Keep an eye on the soil’s moisture content and adjust watering as necessary, taking into account the needs of the individual tree.


Applying a layer of mulch around the base of your large trees offers numerous benefits. Mulch helps retain moisture in the soil, regulates soil temperature, suppresses weed growth, and improves soil fertility. 

Apply a 2-4 inch layer of organic mulch, such as wood chips or bark, around the tree, keeping it a few inches away from the trunk. Regularly replenish the mulch as it decomposes over time. Avoid piling mulch against the trunk, as it can promote rot and attract pests.

Trimming and Pruning

For huge trees to remain healthy and structurally sound, tree clearing is essential. To stop the spread of diseases and enhance the tree’s overall look, prune away dead, diseased, or damaged branches. 

The canopy can be made thinner to improve air flow and light penetration. For large-scale trimming projects, it is advisable to contact a professional arborist because they have the knowledge and experience to guarantee that the right pruning methods are used without endangering the tree.


Fertilizing can provide essential nutrients to support the growth and health of large trees. Conduct a soil test to determine any nutrient deficiencies and consult with an arborist or horticulturist for appropriate fertilizer recommendations. 

Apply a slow-release fertilizer specifically formulated for trees, following the instructions and dosage guidelines. Avoid excessive fertilization, as it can lead to nutrient imbalances and potential harm to the tree.

Protection from outside influences

The health of large trees in your backyard may be impacted by environmental conditions. Take precautions to shield them from potential harm. For instance, to prevent soil compaction and root damage during construction operations, install barriers or fences around the tree’s drip line. 

Avoid using large tools or machines close to the tree’s root zone. Additionally, during extreme weather, cover trees with mulch or shade to protect them from excessive heat or cold.
