Acacias VHT114

Learn about the identification and botany, and culture (planting, watering, feeding, propagation) of the wattles. Around 50 species are studied in detail. You also learn about the commercial uses of Acacias as building materials, food plants, for tanning, craft, etc.

Acacias occur naturally mainly in dry tropical or mild temperate regions. Authorities vary on the exact number of species that exist, but more are native to Australia than anywhere else. Other species are as wide spread as Africa, America and South East Asia. Some occur naturally in snow prone areas, and can withstand very harsh winter conditions.

Acacias are mostly shrubs and trees. Some are very low growing and can be used effectively as ground covers. Growing Acacias in areas outside of their natural conditions can be somewhat unpredictable and variable.

• Some have adapted well as garden plants, or as windbreak or screening plants.
• Others have become weeds when transplanted beyond their indigenous area.
• Some have other uses and a number are even farmed commercially to produce products as diverse as extracts for medicines, oil for the perfume industry, edible food products, and timber products for fencing, furniture and building construction.

This course attempts to develop your ability to both identify and use different Acacias.

st1:*{behavior:url(#ieooui) } Acacias have more uses than most people realize.

• The most obvious use is as a garden plant; or perhaps a timber.
