Non-Invasive Tree Roots

non-invasive tree roots

Non-invasive tree roots are a beautiful addition to your yard, providing beauty, structure, and shelter for birds and animals. Many homeowners avoid growing trees in their gardens because the roots can cause home foundations or plumbing pipes to break, resulting in costly repairs. An expert arborist can help you pick out the finest trees for your garden’s layout and those that won’t intrude on your plumbing.

Why Do Most Homeowners Prefer Trees with Non-Invasive Tree Roots?

The roots of a tree are its respiratory system. They absorb water and nutrients from the soil to transport them to the rest of the tree. The roots also anchor the tree in the ground and help it withstand strong winds. A tree’s root system can extend well beyond its branch spread. Some trees, like maples, have very shallow root systems that can easily damage underground pipes and foundations. Other trees, such as oaks, have deep taproots that are less likely to cause problems.

There are several reasons why you might want to choose trees with non-invasive tree roots for your garden:

  1. Avoid damage to your home’s foundation or plumbing: Most people choose trees with roots that are non-invasive to prevent damage to their home’s foundation or plumbing.
  2. Prevent soil erosion: Trees with deep roots help anchor the soil, preventing erosion.
  3. Provide shade and wind protection: Trees can provide shade for your home, reducing your cooling costs in the summer. They can also block out strong winds, providing protection for your home and garden.
  4. Attract wildlife: Many birds and animals rely on trees for food and shelter. By planting trees with less intrusive root systems, you can create a habitat for these creatures in your own backyard.
  5. Improve air quality: Trees produce oxygen and filter pollutants from the air, improving air quality in urban areas.

Which Tree Types Have Non-Invasive Systems?

There are many types of trees with non-invasive tree roots, including:

  1. Oaks: Oaks have deep taproots that anchor the tree in the ground. They are less likely to damage foundations or pipes than other tree types.
  2. Pines: Pines have shallow root systems that spread out wide, making them ideal for preventing soil erosion.
  3. Maples: Maples have shallow root systems that can easily damage underground pipes and foundations.
  4. Ashes: Ashes have deep taproots that make them resistant to high winds. They are also good at preventing soil erosion. 
  5. Elms: Elms have shallow root systems that can cause damage to foundations and pipes if they are not maintained.
  6. Fruit trees: Fruit trees have shallow root systems that can damage foundations and pipes if they are not maintained.

It’s important to consult with an arborist before planting any tree in your yard, as some tree roots can be very invasive. An arborist can help you choose the best tree for your garden’s layout and those that won’t intrude on your plumbing.

Are You Harming Your Soil Ecosystem?

Danville Tree Pruning

The trees on your property are dependent on your soil to be a healthy, safe place for them to grow or just stay alive. If your soil suffers, the trees suffer. If your soil thrives, the trees thrive. You need to be sure you aren’t harming your soil, which would threaten your trees.

However, to do that, you need to know about some of the most common practices which lead to soil damage.

Using Biocides

One of the most common ways people harm soil is by using biocides, which destroy life inside the soil. Healthy soil is full of microorganisms that promote tree growth and nutrition. Unfortunately, when plants are sprayed with pesticides to kill insects, they also end up being absorbed by the soil, which becomes damaged as a consequence. Biocides include everything from pesticides, weed killers, and fungicides, etc.

Moreover, even if the biocides don’t have an immediate measurable effect on your trees or soil, the can remain for decades and damage life in the longer run as they build up.

Removing Vegetation

Another common practice that leads to the damage of soil is through the removal of vegetation. While some people remove ground covering plants to create some landscaping goals, you also need to understand that complete removal leads to the soil being exposed. It also loses the connectivity created by root systems. This, as a result, makes it vulnerable to forces of erosion like wind and rain.

When the soil is exposed to these threats, healthy topsoil is lost, which is a primary layer for plants to grow because it has the most organic matter. Moreover, when the soil is bare, it receives more sunlight, and this causes moisture to evaporate. Finally, it becomes compacted as it dries, which make it harder for the soil to absorb rain.

If you don’t want to destroy the soil, you need to understand the soil’s needs. You need to know the soil needs to be covered, and plants provide this shelter. 

Allowing Soil to Dry Out

When soil is allowed to dry, the rich environment or microorganism that call it home suffer. Organic matter thrives in soil, from living fungi, to earthworms and healthy bacteria, and they all need water to survive.

Remember that your trees can’t make these decisions for you, but it matter to them when you make choices soil management. Swear off biocides, grow ground covering plants, and keep your soil from drying, and your trees will thank you. Silently, by living a long healthy life.

Signs of a Dying Tree

Tree Service Danville

We rely on trees for our livelihood as they provide the oxygen that we breath to survive. This is why many of us feel a kindred connection to trees and the outdoors. However, trees are not indestructible or immortal. They can get sick and do die over time. As with humans, there are signs that you should be aware of so you can quickly identify a sick or dying tree.

 

Loss of Leaves

During the autumn and winter months, it is quite common for trees to lose the foliage. This is very normal. Should a loss of leaves occur in the spring and summer months, this is a clear indicator of a problem. Similarly, if the leaves turn brown and brittle during said months. Sometimes, a sick tree may get reddish/brown leaves in these same months.

 

Inspect the Branches

Beyond the leaves, take a look at the branches of a tree. If no bark exists, this is a sign of an issue. It is called deadwood. Such branches are often prone to falling and be a great area for fungus growth. Should you see such signs, you should contact a certified arborist right away. Even if your tree is not dead, this could be an indication of an infestation and you want to prevent it from attacking the healthier parts of your tree.

 

Absence of Bark

Related to the above, the peeling or loss of bark is a strong indicator of disease. The presence of missing bark can also be caused by things like weed eaters or environmental conditions that make a tree highly vulnerable to bacteria, disease or fungus. While such situations may not be enough to remove the tree, a tree inspection by a certified arborist would allow you to ensure your tree is kept healthy.

 

Trunk Firmness

If the tree’s trunk becomes hollow or soft, it is usually a sign of a dying tree. It is similar to a potato that goes bad. It becomes squishy and if you leave it out long enough it starts decomposing from the inside out. Some signs of such decay are mushrooms, cavities, insect damage, or any of the other conditions discussed above.

 

Roots

Although you are unlikely to see this most of the time, damage to the roots is another indicator of a problem with your tree. Some indications of this issue are soil rising around the base of a tree or visible roots that show decay. Another sign could be a reduction in the tree coverage or a lean in the tree.

Regardless of what the factors maybe that lead you to believe there may be a sickness or death to the tree, a certified arborist can both be a great resource to do a proper inspection and/or do routine preventive care. Contact the certified arborist at Sexy Trees at 925.233.6877.
