The Acacia tree is an exotic tree with feathery, finely divided leaflets. Its stems are sharp and long with medium green leaves and small, yellow flowers. There are many varieties of acacia trees, all of which grow quite easily. These trees have been valued for their inelastic, durable, strong and hard timber for a number of decades. Acacia trees are extremely beautiful and this is why people grow them for landscaping purposes.
Growing acacia trees
These trees can be grown from cuttings, seeds or they can even be graphed. However, if you are using a cutting, it is important to take it during summer. You should also treat it with root hormone and ensure that it stays moist and warm till the roots develop. Growing acacia trees from seeds is much easier. You can clip the lower part of the seeds and let them soak in warm water for two days before they can be sown.
The best kind of soil for acacia trees is light, medium porous and well-drained soil. You should also remember to plant these trees in places where they will get a lot of sunlight. This is because acacia trees are warm weather trees which require the full sun to thrive. However, young acacia trees would need a little bit of sheltering from wildlife.
One of the best things about these trees is that they don’t require too much care and attention. You don't necessariliy have to water your acacia trees every day because they need a slightly dry or moderate climate. It is important to let the soil dry up in between the watering periods. However, ensure that it does not get too dry as it can cause the leaves to drop.
Just as these trees require very little water, their requirements for fertilizers are minimal as well. It is important to fertilize these trees sparingly. During the growth period, using a standard bonsai fertilizer every 15-20 days is a good idea. Once the tree has grown, you can use the fertilizer once in 4-6 weeks. You can also use plant food for the tree, but just once a year.
Pruning acacia trees
Like most trees, acacias also require pruning from time to time. The best time to do this is during the dry months. If you want the best results, it is important that you cut only the dead limbs of the tree. Avoid pruning leafy areas of the tree.
Acacia diseases and pests
The most common disease that acacia trees face is infection of the leaves by anthracnose. The timber of these trees can also suffer a great deal of damage due to goat-moth. Other pests that can affect acacia trees are mites, flies, aphids and thrips. Hard shelled insects like woolly aphids and scale can also infect these trees.
