Tree Roots & Pavers

Just Stumpgrinding regularily receives enquiries on surface tree root systems, whether they are in the way of new construction, damaging concrete, a potential trip hazard, or effecting pavers as seen in the below photo. 

Fig Trees, Umbrella's, Macaranga and Poinciana's are a few of the common surface root trees you will find in the area. However, any tree has the potential to maintain the roots on the surface. This can be due to environmental factors such as soil erosion, inadequate quality nutrients below the surface or lack of oxygen. Roots require oxygen to maintain the health of the tree. How the tree chooses to disperse and grow through the soil is dependant on both soil conditions and characteristics of the tree.

Different tree species display different root systems. A tree with a taproot will dive down vertically into the ground and have smaller roots running out from the main root. A taproot is also more accustomed to droughts as the root can grow quite deep into the ground to find moisture. A Mulga (Acacia aneura) is an Australian species with a taproot. A tree with fibrous roots grow in a mass from the base, which allows the tree to absorb more rainwater and obtain more stability.  A typical example of a fibrous tree root systems are golden canes and palm tree species. 

There is a common misconception that most plants and trees have a taproot. However, for the majority of Australian trees, this is not correct. You will find in tree roots they more commonly will grow laterally. 

Tree root integrity influences the overall health and well being of the tree by 

  1. Absorption of vital nutrients and water 
  2. Tree stability
  3. Storage of energy and nutrients for the tree

When thinking about tree root cutting/grinding it's important to consider -

How many roots can we remove? We need to think about the tree. If we remove all these roots on one side, will the tree still be stable? What are the tree roots affecting? Are they lifting driveway pavers? Back yard pavers? Are the tree roots slowing heading towards the structure of the house? Is there a risk of potential damage to the house structure? How important is the tree? 

Generally, we find grinding a tree root, or two won't pose any serious threat to the health of the tree. If you think you want to remove all visible surface roots, it would be in your best interest to consult a qualified arborist. (Call us for our recommendation)

Another option, if you have tree roots that are exposed due to soil erosion and arent posing any potential threat to pavers, housing structures or concrete, you could add roughly two to four inches of quality mulch or topsoil. By covering the exposed roots with soil or mulch, this will reduce the potential trip hazard and assist in protecting the roots. 

If you think you may have some surface roots affecting your pavers or any structure call Just Stumpgrinding today for us to assist you in taking care of these tree surface roots. 

We do ask if you suspect you have tree roots lifting any pavers we need the roots to be exposed before we can give you an accurate price.
