Weeping myall - Acacia pendula

Description and Uses

Acacia pendula (Weeping myall) is a tropical tree from Southern Australia. It is mainly grown for its timber crops (long shelflife), The crop is harvested by total removing. It starts flowering after 5 - 10 years. The first yield will be 0 kg but in its top season there will be a yield of 8 meters long trunk. There is A. pendula leaf-oil extracted by steam distillation from the tree`s fresh leaf yielding 0.1 - 2% oil. The tree`s wood is called wattle wood and has a density of 980 - 1000 kg/m³. Regarding firewood production the tree`s growing speed is very slow, its energetic value is 4700 ckal/kg and the wood`s drying speed is fast; for firewood production it is not ideal. After 50 years the tree can be totally removed as it reached its commercial and ecological goal. Acacia pendula has a lifespan of 160 years.

Environmental limitations

The tree is 10 meters tall. It is very slow growing and tolerates not less light than partial shade. Acacia pendula has a deep root-system and forms symbiotic relations (endo and ecto mycorrhiza). It is able to fix nitrogen with Microbacteriaceae bacteria. The tree`s flower-morphology is hermaphroditic and is pollinated by bees. Acacia pendula is evergreen and a bit allelopathic and has no thorns.

Acacia pendula thrives in an altitude of 0 to 1000 meters above sea-level (tropical). The minimum temperature is -4°C and optimally between 15 - 35°C. The optimal rainfall is 450 mm/year. Without irrigation the annual rainfall should be between 150 - 600 mm (L/m²). The optimal soil-pH is between 5.0 - 8.0 in a soil texture of loam. To salt it is a bit tolerant to wind tolerant and to fire a bit tolerant.
