GUIDE TO BACKYARD TREE CARE
Selecting trees for your yard
If you were buying a car, you’d want to know what its safety features were and its fuel consumption. Buying a tree should be no different. Here are some things to consider when buying a new plant or tree.
How large will your tree grow?
Consider the tree’s future height, width and root growth and keep in mind:
• small backyards can only accommodate small to medium trees
• it is important to keep trees well clear of power lines, roofs and gutters
• your neighbours may not appreciate a tree overhanging their property.
Conditions – sunlight, soil, water
Trees need the right conditions to grow healthy and strong. It is important to only grow trees that your property can support. Choose waterwise trees appropriate for your soil type and light levels.
What do you want from your tree?
Understanding what you want from your tree will help you select the right species. Planting trees on the western side of your home will provide important summer shade. The right tree could also make a great privacy screen, a landscaping feature, a home for wildlife, or source of home-grown nutrition.
Consider planting a native tree
Trees native to Brisbane are suited to most soil types. They are easy to maintain, don’t require excessive fertilizers or pesticides, provide food and shelter for wildlife and don’t become weeds. A list of suitable species can be found at www.brisbane.qld.gov.au/environment
Before you buy any tree it pays to do your homework. This will help you choose the best species and planting location for your tree. Your local nursery can provide advice and guidance. A little thought now can save you money in the future.
The truth about tree roots
When you have trees it is important to check for leaking water and sewer pipes. Tree roots don’t usually crack pipes, but they will be attracted to any leaking pipes you have, and could make the problem worse. This is another reason why considering your tree’s root system and the placement of your trees is so important. Similarly, don’t plant too close to retaining walls, fences and other structures and prune your tree as it grows to avoid any problems for your property.
Understand your tree’s critical root zone
A tree’s critical root zone is the area directly underneath the canopy of a mature tree, right down to the root structure. All activities in this zone have a direct impact on the tree and its roots.
Tree health and stability are linked to root health. Any damage to the roots can weaken branches in the tree’s canopy and may result in unstable trees during extreme weather conditions.
