Tree roots interfere with landscaping plan

[cwrandolph]

I have been thinking about installing a ring around a tree in my yard using retaing wall blocks. It's a maple tree about 20" in diameter and I was planning on a ring about 10-12' in diameter. The area around the tree is sloped so the high areas of the circle would get one layer of block and the lower areas would get 2 or 3 layers. I would need to dig out some soil as needed to make the layers level. The problem is that there are roots everywhere. I would need to chop out a lot of roots to make this happen. This is a large healthy tree so maybe removing these surface roots wouldn't hurt it. Or maybe there is another option. I'm not stuck on using the retaining wall blocks. Looking for options/advice - thanks in advance.

Welcome cwrandolph.

The surface roots of a tree are the feeder roots taking in nutrients and water. If you remove any great amount of those it's likely you'll damage the tree, or worse kill it.

Is it necessary to create a ring?

 

[cwrandolph]

I surely don't want to damage the tree - just planning to add some mulch and thought that the ring would keep it in place.

Maybe a ground cover (ivy?) would be a better option?

Well composted mulch is fine, but it doesn't need anything to ''keep it in'' Just put the mulch around the tree, but not right up to the trunk. It will look much better like that too - more natural. It certainly would not like concrete and blocks, and that would not be a good look either. It's usually best to apply mulch after rain.

Ivy can be a thug and difficult to get rid of once it gets a hold. There are many ground cover plants that would be less intrusive.

We use a triangular crushed limestone to great effect. It locks into place even on steeper inclines and percolates water and air just fine while retaining moisture and lowering ground temperatures. The decorative plants we use like liriope absolutely love stone to hide roots under as the moisture is even across the highs and lows of the year.

Tree rings are out because they do more harm than good. That Maple may not be there much longer if you do anything to the roots. IF you put stone around the flair you will add too much heat in the summer and too cold in the winter. Just leave it alone.

Did something similar awhile back using left-over brick pieces. Just placed a loosely stacked ring around the tree - right over any roots - and it looked really good. Large stones would also work well, something heavy enough that it will stay in place along a grade.

Is it necessary to create a ring?

1. Alternative Materials: Instead of using retaining wall blocks, you can explore other materials that are more flexible and less intrusive to the tree roots. Options such as flexible rubber or plastic edging, natural stone, or even creating a raised bed with organic materials can be considered. These materials are less likely to disrupt the root system and still provide a defined border around the tree.
2. Adjusting the Design: If you still prefer to use retaining wall blocks, you can modify the design to minimize root disturbance. Rather than creating a complete circle around the tree, consider making a partial ring or a more irregular shape that allows for the existing roots to remain undisturbed. Find out more

When installing a ring around a tree using retaining wall blocks, it's important to consider the impact it may have on the tree's roots. Maple trees, like any other tree, rely on their root system for stability and nutrient absorption. Removing or cutting too many roots can potentially harm the tree.
Here are a few options and advice to consider:

1. Alternative Materials: Instead of using retaining wall blocks, you can explore other materials that are more flexible and less intrusive to the tree roots. Options such as flexible rubber or plastic edging, natural stone, or even creating a raised bed with organic materials can be considered.

Rather than creating a complete circle around the tree, consider making a partial ring or a more irregular shape that allows for the existing roots to remain undisturbed. This way, you can still achieve your desired aesthetic while reducing the impact on the tree.
3. Consulting an Arborist: To ensure the health and longevity of the tree, it's advisable to consult with a professional arborist. They can assess the situation, evaluate the potential impact on the tree, and provide guidance on the best course of action. An arborist's expertise will help you make an informed decision and carry out the project without causing harm to the tree.

Remember, the overall health and well-being of the tree should be the top priority. Taking appropriate measures to minimize root disturbance and seeking professional advice will help you create a landscape feature while maintaining the tree's vitality.
