Benefits of Mulching Your Older Trees
The benefits of mulching around mature trees greatly outweigh the potential drawbacks.
It Limits Weed Growth
Limiting weed growth near the base of the tree reduces the chance of nicking the trunk or exposed roots with a lawn mower or weed trimmer. Mulch prevents the weed seeds from receiving the sunlight they need to germinate.
It Helps Retain Soil Moisture
Mulch holds moisture in the soil. It keeps sunlight off the dirt near the trunk, limiting the loss of moisture to evaporation. With more moisture available, the tree’s roots can continue to supply the plant with the water it needs to thrive.
It Reduces Temperature Extremes
Mulch maintains the soil around the trunk at a more consistent temperature. Avoiding rapid temperature changes allows the roots to thrive. Temperature extremes can cause damage to shallower roots, potentially affecting the tree’s stability.
It Adds Nutrients to the Soil
As the natural mulch decomposes, it deposits nutrients into the soil that the tree’s roots can use to feed the tree. Even mature trees can benefit from a nutrient boost to maintain their health as they continue to grow. Mulch decomposition is a slow process, though, so you might still need to add fertilizer occasionally.
Concerns About Adding Mulch for Mature Trees
If you’re asking yourself, “Should I mulch around mature trees?” know that the job must be done with care. To properly much around older trees, you need to watch for some potential problems, including:
- Suffocating the roots
- Attracting insects and rodents
- Compacted mulch
- Excess moisture retention
To avoid these issues, keep the mulch a few inches away from making contact with the trunk. Use only organic mulching materials that will slowly decompose rather than compacting. Rake the mulch occasionally and remove any older mulch that isn’t decomposing on its own. Keep the mulch layer at a depth of no more than four inches.
You may want to rely on professionals for adding mulch. Performing tree care that involves adding mulch to mature trees requires precise measurements. The professionals will inspect the area around the tree and determine how much mulch to add, if any.
