Choosing the Right Landscape Trees

Landscape trees planted 50 years ago are not the same as trees planted today. Good landscape trees make a lot of sense, but what makes a good landscape tree in today’s modern landscapes?

Small Trees Please – Big Winds Damage Urban Areas

Every time big winds hit urban areas there is a lot of damage. I just typed in Fallen Tree into a news service, and it is amazing how many people are hurt and how much property is destroyed every week by trees around the world.

Although deaths from trees are rare in Australia, property damage is not. Large Eucalypts and other large trees can be problematic in urban areas. There is a trend to using smaller safer trees that have a better reputation. Trees like Luscious, Sublime, Sweeper, Red Head and Pinnacle are being used more and more.

How important is safety as a tree selection criteria? What are the other important criteria? Trees are an important part of urban life and have many benefits. Choosing the right tree will ensure the benefits without the problems.

Getting street tree selection right

Getting street tree selection right

SUBLIME™ Acmena smithii 'DOW30' PBR

According to recent research into what makes a suburb appealing, good street trees are one of the main differences between a good suburb with strong house prices and a less desirable place to live. Quite simply people equate green, leafy streets with prosperity and good living.

However, many of the gracious trees that line the streets in our most desirable suburbs would not be planted today. Trees such as poplars, elms and plane trees or jacarandas and poincianas in warmer climates, that were favoured by town planners of yesteryear, are now seen as too big and offering too many potential maintenance problems to be suitable to plant today.

Many of these trees are no longer selected for street planting and others are being removed and replaced with different species as they reach the end of their lifespans.

Elms for example, which survive in streets and parks in southern Australia, are seen as a ticking time bomb as these trees have been devastated by Dutch elm disease in most other parts of the world. So far, although we have the vector that spreads the disease (the elm leaf beetle), we don’t yet have the pathogen in Australia.

Even street trees widely planted in recent years are being reassessed for their long-term suitability. In more recent times the pyramidal shape of the Bradford pear saw it being widely planted city and suburban streets. While these now mature trees do look spectacular, especially in spring blossom and autumn leaf colour, they present maintenance problems as the variety chosen, although ornamental, does produce small fruits that form a slip hazard on pavements in summer and autumn. As well, its branches were often subject to wind damage and splitting.

Some factors that make large, spreading trees so problematic for use as street trees can be overcome with planning and careful management. Underground or bundled overhead wires and broad planting strips to accommodate the tree’s growing roots and water needs are necessary for safely growing and maintaining large, spreading street trees.

Where these demands can’t be met, those making street tree planting choices need to select tree varieties that can live in harmony with the street and its users with minimum maintenance.

I just love the dense shape of this tree, and it’s beautiful lime coloured new growth. Yes this is a tree not a shrub. Most Lilly Pillys are grown as a shrub, but not Sublime™ Acmena, it’s a tree.

Sublime™ Acmena is extremely psyllid resistant, and drought and frost tolerant.  Sublime™ Acmena is ideal for screening, hedges, topiary or garden features. The foliage is dense all the way to the ground level.

Masses of white fluffy flowers appear in Summer that develop into a deep mauve berry, giving an excellent contrast against the foliage. These berries are also edible.

Sublime™ Acmena  is excellent for attracting birds to your garden. Sublime gets about 5 metres tall.  Sublime™ Acmena, its got to be one of Australia’s best trees.
