Should You Trim Japanese Maples That Touch the Ground?
Understanding Japanese Maples
Japanese maples (Acer palmatum) are a popular and iconic tree species known for their stunning foliage and unique characteristics. They are native to Japan and have been cultivated for centuries for their ornamental value. However, Japanese maples are notorious for their tendency to grow vigorously and spread quickly, which can make them challenging to manage.
Why Japanese Maples Grow Vigorously
Japanese maples are a type of deciduous tree that grows rapidly in its early years, producing a large canopy and a dense root system. This rapid growth is due to the tree’s ability to produce new roots and stems, which allows it to absorb more nutrients and water from the soil. As a result, Japanese maples can grow up to 3-4 feet per year, making them a challenging tree to control.
The Problem of Japanese Maple Roots
One of the main issues with Japanese maples is their tendency to grow roots that can spread far beyond the tree’s canopy. These roots can grow up to 10 feet deep and 20 feet wide, making it difficult to prune or control the tree’s growth. Additionally, Japanese maples have a shallow root system, which means that they can be susceptible to root rot and other diseases if the soil is not well-drained.
Trimming Japanese Maples That Touch the Ground
Trimming Japanese maples that touch the ground can be a bit tricky, but it’s essential to do so to prevent the tree from becoming too large and unruly. Here are some tips to help you trim your Japanese maple that touches the ground:
- Use a sharp, clean pruning tool: A sharp, clean pruning tool is essential for making clean cuts and preventing the spread of disease.
- Make clean cuts: Make clean cuts just above a node (where a leaf meets the stem) to prevent the tree from producing new growth from that area.
- Cut at the right time: Cut your Japanese maple in the late winter or early spring, when the tree is dormant. This will help prevent the tree from producing new growth that can spread and cause problems.
- Cut back to a desired height: Cut your Japanese maple back to a desired height, taking into account the tree’s mature size and the amount of sunlight it receives.
- Remove any dead or damaged branches: Remove any dead or damaged branches to prevent the spread of disease and to maintain the tree’s overall health.

Trimming Japanese maples that touch the ground can have several benefits, including:
- Improved tree shape: Trimming your Japanese maple can help improve its overall shape and structure, making it more aesthetically pleasing.
- Increased sunlight penetration: By cutting back the tree, you can increase sunlight penetration and promote healthy growth.
- Reduced risk of disease: Trimming your Japanese maple can help reduce the risk of disease by removing any infected or damaged branches.

Common Mistakes to Avoid
When trimming Japanese maples that touch the ground, there are several common mistakes to avoid, including:
- Cutting too much: Cutting too much of the tree can cause it to become too large and unruly, making it difficult to control.
- Not making clean cuts: Not making clean cuts can lead to the spread of disease and to the production of new growth that can cause problems.
- Not cutting back to a desired height: Not cutting back to a desired height can lead to the tree becoming too large and unruly.
- Not removing dead or damaged branches: Not removing dead or damaged branches can lead to the spread of disease and to the promotion of unhealthy growth.
