Trees grow in some of my fondest childhood memories – the pine with my tree fort, the maple with my swing, the shady oak, the spruce with the nest I would check for baby doves. As well as memories, trees provide food and shelter for wildlife and prevent soil erosion. They green urban areas, lessen noise and cool city streets. Trees can reduce winter heating costs by up to 15 per cent and lower summer air-conditioning bills, too. Most important, trees absorb carbon dioxide. And early spring is a great time to plant them.
Making the right choice
Before purchasing any tree, ask yourself: Why do I want it (for shade, privacy, fall colour, a focal point, attracting birds, a windbreak)? What is the maximum mature height and spread that suits my lot? Do I want a deciduous or evergreen tree? Determine your hardiness zone, soil type and sun exposure. Consider what may be underground (pipes) and overhead (wires), and, if you’re planting near your house, consult with nursery staff to choose a tree with roots that won’t damage the foundation.
Getting it home safely
Wrap the foliage before heading home, and avoid bruising the bark and compacting the roots in transit, then keep the tree moist and shaded until planting time.
Planting it properly
Dig a hole twice the diameter of the root-ball and one-and-a-half times its depth, discarding all grass and weeds, then rough up the sides and bottom with a gardening fork. Using triple mix (toss in a handful of bonemeal), fill the base of the hole until the top of the root-ball will sit just above ground level. Gently untangle any encircling roots and prune off any damaged ends, then centre the root-ball in the hole. Continue to fill around it and tamp down firmly, forming a ridge around the edge of the fill to create a water reservoir. If the tree is taller than one metre, stake it at opposite sides, perpendicular to the prevailing wind. Finally, mulch thickly to within 15 centimetres of the trunk .
Watering it well
Water deeply about twice a week for the first three months.
