Trees To Avoid
To minimise maintenance and hard work, it is very important to seek advice before you plant. Any plant (whether it be a tree, shrub, climber or ground cover) in the wrong place can ruin your garden, damage your house and even cause problems with the neighbours. Here is Don’s list of problem trees, and he’s also thrown in a few invasive climbers and shrubs for good measure!
Camphor laurel (Cinnamomum camphora)
From China, Taiwan and Japan this evergreen tree grows up to 18 metres (60’) high and nine metres (30’) wide. It self-seeds readily and has become a serious weed in rainforest areas of Australia.
Evergreen figs (Ficus sp.)
Many evergreen figs start out as indoor plants and then when they get too big, they are planted out in the garden. They include Hill’s weeping fig (Ficus microcarpa var. hillii) weeping fig (F. benjamina), Moreton bay fig (F. macrophylla) and Port Jackson fig (F. rubiginosa). Planted in the garden, these figs develop into huge trees, with invasive roots that crack water pipes and damage foundations.
Evergreen alder (Alnus acuminata)
Also known as A. jorullensis, these trees are not suitable for small backyards as they grow to a massive size. The roots will break pipes, jack up fences and cause paving to buckle. The canopy quickly spreads across a small yard, blocking the light, while the roots use up all available soil space.
Weeping willow (Salix babylonica)
These are very adaptable trees and will easily multiply by layering, or form roots from any part of a stem or branch. They also have a strong suckering habit. Some councils include this tree in their weed list.
Poplar trees (Populus sp.)
As a group, poplars are a bit of a worry. They should not be planted near houses. In humid coastal areas, a disease called Poplar Rust controls the trees and is therefore not such a problem. Poplars love deep moisture and the roots will travel long distances to hunt out moisture. They are notorious for blocking drains and lifting paving. Some species sucker freely from the roots.
Liquidambar (Liquidambar styraciflua)
Liquidambars are large, fast-growing trees that can reach 25 metres (82’) high and spread to around 12 metres (39’). Although liquidambars are beautiful trees, they do have strong, aggressive root systems. If a liquidambar is planted too close to storm water pipes, the root system may completely clog the pipes.
Golden robinia (Robinia pseudoacacia ‘Frisia’)
This was a vogue tree in Australian gardens in the 1980s and it is still tremendously popular today. However, they are prone to suckering because the variety is grafted onto a vigorous understock, R. pseudoacacia, also known as the false acacia. The false acacia will grow to 20 metres (60’), has green leaves and thorns. If roots are damaged, i.e. by a mower or whipper snipper, or if the roots hit an obstacle, such as heavy clay soil, they will produce suckers that may turn up several doors down from the original tree. Any stress may also induce suckering. Suckers are very difficult to control once they start appearing. They should be cut off with a clean sharp cut as close as possible to the root.
Jasmine (Jasminum polyanthum)
This vigorous evergreen climber from China grows quickly to a height of 6 metres (20’). It can become invasive very quickly. It is difficult to control as it spreads above and below ground and the wiry stems are quite tough to remove. It sends out new shoots from the roots and can only be controlled with continual spraying.
Bog sage (Salvia uliginosa)
This upright, branching perennial from South America produces long racemes of sky blue flowers in summer. It may reach 1 -1.8 metres (3-6’) and continues to send out underground rooting shoots that may become invasive in good or moist soils.
Australian indigo (Indigofera australis)
This evergreen Australian native grows to 1-1.8 metres (3-6’). It produces pink flowers followed by brown seed pods. This plant tends to sucker and can be invasive in the garden.
Golden bamboo (Phyllostachys aurea)
There are two forms of bamboo – running (monopodial) and clumping (sympodial). Running bamboos such as the golden bamboo spread so successfully that they soon invade areas where they are not wanted. If you really want to plant bamboo, plant a clumping species.
Always seek information before you plant. Horticulturists at your local nursery can advise on suitable trees for your climate and situation.
Magnolia Root System – Are Magnolia Roots Invasive
Nobody can deny that magnolia trees in bloom are a glorious sight. Magnolias are so commonly planted in warm regions that they have become almost emblematic of the American South. The fragrance is as sweet and unforgettable as the huge, white blossoms are lovely. Although magnolia trees are surprisingly low maintenance, magnolia tree roots can cause problems for a homeowner. Read on to find out the type of magnolia tree root damage to expect if you plant these tree close to the house.
Magnolia Root System
Magnolias, like the glorious southern magnolia (Magnolia grandiflora), the state tree of Mississippi, can grow to 80 feet tall. These trees can have a 40-foot spread and a trunk diameter of 36 inches.
You might think that magnolia tree roots head straight down in order
to stabilize these big trees, but that is far from the truth. The magnolia root system is quite different, and the trees grow large, flexible, rope-like roots. These magnolia tree roots grow horizontally, not vertically, and stay relatively close to the soil surface.
Because of this, planting magnolias near houses can lead to magnolia tree root damage.
Planting Magnolias Near House
Are magnolia roots invasive? The answer is yes and no. While the roots are not necessarily invasive, you may get magnolia tree root damage when the trees grow too close to your house.
Most tree roots seek a water source, and magnolia tree roots are no exception. Given the flexible roots and the shallow magnolia root system, it is not difficult for magnolia tree roots to head for cracks in your plumbing pipes if the tree is planted sufficiently close to the house.
Most tree roots do not actually break water pipes very often. However, once the pipes fail at the joints due to aging of the plumbing system, the roots invade and block up the pipes.
Remember that the magnolia root system is very wide, up to four times the width of the tree canopy. In fact, magnolia tree roots spread farther than those of most trees. If your house is within root range, the roots can work their way into pipes under your house. As they do, they damage your home’s structure and/or plumbing system.
Mistakes to Avoid when Growing a Magnolia
The varying species of the magnolia tree make the magnolia a plant that has many different varieties suited for many different regions, climates and circumstances. No matter which species you choose to go with, you are sure to have a wonderfully beautiful plant that will add volumes to any garden space. Magnolias are fairly easy plants to care for and do not attract many pests, these factors coupled with the variety available, make the magnolia an ideal garden plant. This guide will show you some common mistakes to avoid when growing magnolias.
When choosing a magnolia, it is very important to choose one that grows well in your region. Magnolias that grow in the north require different care than those native to the southern regions. If you’re in the north, the best time for planting a magnolia is the spring time, while southern magnolias do best when planted in the fall. Proper magnolia spacing is also important to avoid overcrowding and ensure the most growth. Most magnolia trees grow to be about ten to fifteen feet in width, so planting them fifteen to twenty feet apart from each other allows for the most success. Giving these plants northern exposure will help keep their budding and flowering schedules on track, giving you the best blooms possible.
In the hotter months, newly planted magnolia trees need plenty of water. Under watering in the early stages of the trees life is one of the most common reasons a magnolia tree would fail. Once your magnolia tree is established, it will need far less watering and usually will only require water if the soil doesn’t hold moisture or if there happens to be a drought. Fall is the best time to fertilize your magnolias. You will want to make sure to lay enough fertilizer by laying it under the circumference of the tree and out past the tree by about one to two feet. A common mistake to avoid when fertilizing is to not lay the fertilizer all the way up to the tree trunk. You don’t want the fertilizer touching the trunk but to begin a few inches outside of the trunk. Much like with water, once your magnolia tree is well established you won’t need to continue fertilizing it so make sure you keep this in mind to avoid over fertilization.
If you are considering a magnolia companion, you should look for plants containing spring bulbs. These plants will bloom in unison with your magnolia and produce a prettier, fuller garden. Daffodils, hellebores and bluebells all work well and produce beautiful bouquets in unison with the magnolia tree.
Once you’ve got these things in mind it becomes quite easy to avoid most of the mistakes made when planting and growing magnolias. Once your magnolias are established and mature they require very little care so once you’ve passed the toughest stage of getting them established you can sit back and enjoy some of the most beautiful trees this planet produces.
How Far do Tree Roots Grow Down
Reply Robert December 20, 2010 at 11:22 am
I would recommend that you should take a look at the following resources, and share them with condo staff making the decision on new design of the sidewalks.
Typically the problem has to do with the specifications used to create a sidewalk. With proper design tree roots and sidewalks can safely coexist and properly function together.
1. Tree City USA bulletin #3 – Resolving Tree-Sidewalk Conflicts
2. Tripstop – Articulating Sidewalk Joint System
-Ways to Save Trees
-Construction Practices to Save Trees
3. Up By Roots, by James Urban, FASLA, ISA
Up By Roots is a manual for landscape architects, architects, urban foresters, and planners who are designing, specifying, installing and managing trees in the built environment. Part One discusses basic soil science and tree biology and their relationship to healthy trees. (Including good design concerning trees & sidewalks.)
Part Two explains the process of planning and implementing landscape designs to ensure healthy trees that can improve the quality of places where people live, work and play. The book contains numerous illustrations and data in graphic form to provide guidance in the design of healthy soils and trees.

Ask Wayne Hinton about the use of Rootmaker root barrier fabric. I believe they are starting to look at this product in the design of safer sidewalks.
6. City of San Diego – Street Division – Urban Forestry
As for which types of root barrier work best…contact your San Diego Urban Forestry to see which methods work best in your community. The answer may depend on your soil type and drainage.

I hope these resources prove to be useful. Please let me know if you have any questions. Thank for contacting the Foundation and for caring about trees.
