When Trees Meet Ponds: What to Consider When Building a Pond Near Trees
A garden that can accommodate both a pond and a healthy and vibrant tree is the ideal setting in which to relax and unwind during the spring and summer months. However, when planning to build a pond in your garden, you need to be aware that trees and ponds aren't always compatible. For example, tree roots can sometimes break through pond liner putting the lives of your fish at risk and ruining all your hard work.
That doesn't mean that ponds and trees can't coexist in the same space. Before building your pond, consider several factors to avoid any future problems that might occur.
The Type of Tree and Its Root System
Ascertaining the species of tree in your garden should be your first task. Many trees are as large below ground as they are above, but not all trees have aggressive root systems.
Some tree species such as silver maples, red maples, willows, poplars and elms have root systems that spread quickly to seek out nearby moisture. These roots will be attracted to your pond and eventually pierce the pond liner.
However, if you have a big enough garden, you may be able to keep your pond far enough away from the tree to avoid this problem.
The Distance between the Tree and the Pond
If your tree is one that has an aggressive root system, but you have a large garden you can avoid any future problems by building your pond and water features at least 20–30 feet from the tree.
The Debris the Tree May Drop in Your Pond
You should also consider the debris that a tree may produce throughout the year. Trees such as oak trees can drop blossoms, seeds, twigs, branches and leaves in your garden. If your pond is too close to a messy tree, you may need to place a net over it to prevent any debris from clogging it up and affecting the water quality.
You May Have to Choose Between the Tree and the Pond
If you already have a tree and a pond in close proximity and have been struggling to protect your pond from tree root damage, you may have to choose between the two. You need to decide which of them is more valuable to you: the shade and beauty the tree provides or the tranquillity of your pond?
To help you make a decision about where to place your pond, you could hire an arborist to assess your tree and offer you some advice on how to proceed. Even if you decide on tree removal, you could replace it with a different species, one that is less of a risk whilst still providing shade and greenery in the summer months.
