Safety & Hazards

Especially in times of drought, many Acacia species can concentrate high levels of the toxin Hydrogen cyanide in their foliage, making them dangerous for herbivores to eat.

GrowthFast

Acacia neriifolia is a plant of the warm temperate to subtropical zones of eastern Australia, where it is found at elevations up to 1,100 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 32°c, but can tolerate 8 - 39°c[1]. When dormant, the plant can survive temperatures down to about -5°c, but young growth is more tender can be severely damaged at -1°c[1]. It prefers a mean annual rainfall in the range 600 - 700mm, but tolerates 400 - 800mm[1]. Part of the rainfall often falls as snow[2]. Requires a sunny position. Requires a well-drained soil, growing best on relatively light, often stony soils, but succeeding in textures from sand to clay and also in conditions of low fertility[1, 2]. Prefers a pH in the range 5 - 6, tolerating 4.5 - 6.5[1]. Established plants are moderately drought tolerant[1]. A fast-growing plant[1]. This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[3].

Propagation

Seed - best sown as soon as it is ripe in a sunny position in a warm greenhouse[4].The dried seed of most, if not all, members of this genus has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. Sow the seed in Spring in a greenhouse. As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in a sunny position in the greenhouse for their first winter. Plant them out in late spring or early summer, after the last expected frosts, and consider giving them some protection from the cold for their first winter outdoors. Acacia seeds that have matured fully on the bush and have been properly dried have a hard seed coat and can be stored in closed containers without deterioration for 5 - 10 years or more in dry conditions at ambient temperatures. It is best to remove the aril, which attracts weevils and can lead to moulds forming. The arils are easilyremoved by placing the seeds in water and rubbing them between the hands, then drying the seeds and winnowing them[5].
