Planting a tree is one of the best investments you can make for your garden, but simple mistakes at the start can shorten a tree’s life. At TreeWorks, we’re often called to help with trees that are struggling because they were planted incorrectly. Here’s how to avoid the most common pitfalls.
Not Researching Size and Roots
Check full size of tree and root ball
Before buying a tree, always check the mature height and width. A small sapling may look harmless now, but in 10 years it could be shading your entire house or pressing against your neighbour’s fence. Equally important is the root system. Large species such as liquidambars, poplars and willows develop enormous root balls that can damage pipes, crack concrete, or lift driveways. Always give your tree room to grow safely away from infrastructure.
Planting Too Deep
One of the most common errors is burying the trunk too deep. A healthy tree should show a visible root flare at the base. Roots need oxygen, if they are buried under too much soil, they may develop girdling roots, which wrap around and slowly strangle the trunk.
Mulching the Wrong Way
Mulch is great for moisture and weed control, but piling it against the trunk traps moisture, encourages disease, and hides the root flare. Keep mulch a few centimetres away from the trunk, spreading it in a wide, even layer instead.
