AS spring approaches, the time for fresh starts is upon us, with the celebration of National Arbor Month.

This time of year is a great opportunity to learn more about the importance of trees and why planting one this month will benefit both you and the environment.

Quick fact
Currently the tallest tree in the world is a California redwood, which stands 116m tall.

Planting your own tree
Even though a California redwood might not work in our gardens, there are many trees that thrive in the South African climate. Here are some things to consider:

Sunlight: Most trees love full sunlight, while others prefer dappled shade.

Root system: It’s important to research this because, while some root systems might be shallow (up to two metres deep), others can be quite extensive.

Seasons: The best time to plant a tree is usually spring or early autumn, but it’s best to check which trees work best in which seasons.

Once you have decided on a tree, it’s time to plant!

Directions for planting:
– Dig a hole as deep as the root ball, and at least twice as wide. The wider the better as this allows the roots to spread easily in search of nutrients and water.
– Remove any grass growing around the hole – about half a metre in diameter.
– Fill the hole with water the day before you plant. If the hole is still full the next day, then the spot is not suitable, as lack of drainage will kill the tree.
– Having kept the root ball watered, remove the tree from its container.
– Set the soil in the hole, and spread the roots around the trunk, removing any damaged ones.
– Replace the soil, making sure the crown is at soil level, or just above, and the tree is straight.
– Pat the soil well and create a depression so water will pool there. You can push the soil down with your foot, but watch you don’t stomp on the root ball.
– Water as soon as you are finished planting. If the soil settles, you can add more, but don’t use your feet to firm down the soil while it is wet.
– Add some compost on top of the soil, and slightly beyond the hole. Then add mulch.
– Brush back any compost and mulch from the trunk.
– Only stake if absolutely necessary, and remove stakes and ties after about a year.

Remember: Young trees need regular watering, weeding and fertilising.

Why plant a tree?
– Releasing oxygen through the trunk and leaves, trees are often referred to as the ‘lungs of the planet’.
– They clean the air by intercepting airborne particles, trapping them in leaves and bark.
– They preserve soil by preventing erosion through a web of roots.
– They conserve water by providing shade and decreasing evaporation.
– They support wildlife by providing shelter, nesting and food.
– They sequester and store carbon dioxide, decreasing the concentration of greenhouse gases.
– They cool the planet through shading, and by releasing water vapour through leaves.
– They reduce energy use of a home or office by up to 30% when planted properly around a building.
– They seed the soil through fallen leaves, which turn into nutrients for the tree and surrounds.

Celebrate spring and do your part for the planet by planting a tree this National Arbor Month!
