1. Tree Assessment

Inspecting mature trees can be a daunting task. Trees can reach immense heights and have complex root systems that are difficult to assess. Take a systematic and measured approach to achieve the maximum out of an inspection.

  • Start by looking at the tree from a distance and pay attention to any visible signs of stress and damage. Use a ladder to inspect the tree crown and any visible dead and diseased leaves.
  • Examine tree branches and try to find symptoms of tree disease, such as cankers and discoloured barks. Check for obvious structural issues such as splits, cracks, and hollows.
  • Assess the tree trunk, and inspect the roots and soil. Search for signs of soil compaction, root rot, and girdling. After finding potential issues, customize a treatment plan before they become threats to tree health care.

2. Soil Testing

Soil testing helps understand nutrient deficiencies and other issues the tree might be facing silently. To begin the process, take a soil sample from the tree root zone.

  • Use a spade or trowel to collect the sample from several locations and combine them in a bucket for testing. Next, take the sample to a lab for analysis.
  • The lab will measure the pH, Nitrogen, Phosphorus, and Potassium levels. Once you have the result, you can plan the treatment and help the tree grow well.

3. Tree Fertilization

Fertilize your trees in the early spring before the leaves start emerging. It is considered the best season for mature Tree Fertilization. Prefer using slow-release fertilizers to avoid encountering overgrowth issues.

  • To start the process, choose a fertilizer specially formulated for mature trees, as regular fertilizers can burn the roots.
  • Spread the fertilizers evenly around the tree base and avoid involving the trunk. Use enough fertilizers to cover the entire root zone equal to the width of the tree canopy.
  • After fertilizing, water the area thoroughly to let the soil absorb micro-nutrients. At last, keep an eye on tree growth to identify signs of nutrient deficiencies, pest infestation, and other problems concerning tree health care.

4. Tree Pruning

You must be cautious while Pruning Mature Trees because it can damage the tree extensively. Vigorous pruning reduces leaf surface area that wounds the tree and leads to an energy deficit.

  • Create a detailed plan after inspecting the tree thoroughly. While pruning mature trees, you should focus on eliminating dead, diseased, crossing, overgrown, rubbing, and rotten tree parts.
  • Once you have identified them, use sharp pruning shears or a saw to remove them. Always cut the branch at the correct angle, making it above the branch collar.
  • Use a sealant to protect the cut area from disease and decay. With the technique and tools, you can improve the tree structure and keep it healthy for the future.

5. Tree Mulching

Mulching mature trees is way harder than mulching young and growing trees. You may struggle with the right technique and direction while handling the tree. Use these tips to effectively mulch the tree.

  • Remove existing grass and weeds present around the tree base. Then outspread a layer of mulch base around the main trunk, and avoid piling it.
  • Two to four inches is the recommended depth of the mulch layer. Spread the mulch base uniformly and cover the entire root area.
  • Avoid clamping the base together in a single place. Water your tree to provide extra moisture and help the mulch settle better.

6. Tree Irrigation

Mature trees need a specific amount of water to stay vigorous, but an inadequate quantity can be detrimental to tree health. To overcome this issue, use a slow, deep watering method. The method gives the tree a deep drenching once or twice a week. Follow these steps to properly water the mature tree standing in your yard.

  • Give the tree enough water that penetrates the top 12-18 inches of soil. Set up an irrigation system, use a sprinkler or soil moisture probe to avoid over-watering, and give the right amount of water.
  • Irrigate the tree at least once a week according to requirements. Water twice or thrice a week in dry climate areas or during drought season.
