Small space or specific need? Landscape designer
Tim Davies says there’s a tree to suit your situation
Evergreen ash and waterhousea are two great examples of fast-growing trees frequently used in landscape
applications. These trees can grow up to 1.5 metres per year in a sunny position with well-drained soil under
irrigation. For the best start, plant with soil conditioner that’s mixed 50/50 with your site soil. Water in well and stake
to avoid leaning or crooked growth (remove as the tree is able to support itself ).
Evergreen ash This tree grows to eight metres high and four metres wide, and has dense foliage with
medium-sized green leaves. Small, white flowers appear during spring.
Waterhousea floribunda This has a weeping habit, with dark-green, narrow, shiny leaves and produces small,
white flowers. It grows to 10 metres high and eight metres wide.
Trees like the Tahitian lime are
good choices for small spaces.

When selecting trees for small spaces, several issues
must be taken into consideration. Firstly, trees must not
have an invasive root system; secondly, they must not
grow too big; and, lastly, they must be selected for their
ability to grow in the available light. Try these options:
• Frangipani (Plumeria) An architectural, deciduous
tree. The frangipani is ideal as it can be pruned to suit
your space, will grow in most light, flowers in various
colours and has deciduous and evergreen varieties.
• Magnolia ‘Little Gem’ This is a fantastic, compact
tree that can be used in various locations in landscapes,
such as hedging or as a single specimen plant. Its
glossy green and brown leaves are as much a feature
as its large, highly perfumed white flowers.
• Citrus varieties Fantastic choices that can provide
both screening and produce from the same tree –
perfect for those wanting a hard-working garden that
looks good, too. Citrus can be easily pruned or even
espaliered to create a living courtyard wall.
• Crepe myrtle (Lagerstroemia indica) A small
deciduous tree with a vase-like structure, the crepe
myrtle provides beautifully coloured flowers in autumn,
ranging from whites to reds. Under pruned, this tree
develops wonderfully coloured, smooth, mottled trunks.
