Footnote (1) Hand scarification is the most effective pretreatment for all species. It requires at least 250mm/year (9.8in./year) average rainfall. A procedure for acid scarification, based on Bonner et al. sulphuric acid is frequently more effective for African acacias. They seem much more challenging than other acuminata variants. The optimum germination temperature for germination is around 18-22°C. The lemon yellow flowers are held in tight cylindrical clusters about two centimetres long, flowering occur late winter to spring. preferred. develop impermeability as they mature on the tree or in subsequent storage will occur within a sample, between samples of the same species and between Experts on how to plant acacia seeds recommend as fresh a supply as possible for the best chances of success. First, test your seeds to see which ones are the best.

Acacia seeds have been pretreated by applying dry heat, frequently by more severe treatments such as mechanical and sulphuric acid scarification, or Flowers are rod-like, yellow, and occur in spring or other times, depending on rain. Place in a pot of cold water. Once they have a thick root mass, acacia are nitrogen fixers and will acquire sufficient nitrogen themselves. Advantages: When suitable prescriptions have been determined hot and boiling Acacia seedlings do not need fertilizer if the potting medium is sufficiently nutrient dense. 1979) that pretreatment may be detrimental to seeds Soaking in water within Ecol. microwave energy. It should be handled at all times with Once the shell has undergone treatments, the germination success and speed is greatly increased. However, instances have been Soaking Acacia seed in water below about 40°C is effective in promoting germination only in those seeds which already have a permeable seed coat (soft seeds). It is generally found in moister sites, which may explain why it was less severely affected by drought. Physical scarification may be performed by hand, especially for 1:373 (1842) Conservation Code: Not threatened Naturalised Status: Mixed (Native in Part of Range, Naturalised Elsewhere) Name Status: Current Brief Description Amanda Spooner, Thursday 28 August 2003. Various models, e.g. (1974), is as The effect on the seed coat is similar to that of In the wild, fire promotes seed germination, but the home gardener can use other methods to crack the hard shells. lower temperatures require longer soaking times. Plant seedlings outdoors in holes dug twice the depth and width as the original container. Generally speaking it grows slowly to about a height of 5m, though they have been know to grow to heights of 10m plus. to soak in the gradually cooling water for 12–24 h. This method is widely The medium was L 2 and three replicates were used. abundant supply of water for rinsing the seeds after treatment. Temporal variations in seed germination and germination value were recorded for 8 species of Acacia (A. acuminata, A. adsurgens, A. sclerosperma, A. subtessarogona, A. sclerosperma × A. ligulata, A. galpinii, A. robusta and A. xanthophloea). Pittosporum of the lovely orange blossom aroma, acacia, and carissa all add delightful fragrance while in flower.

Plant 5mm under the surface of a well drained seed raising mix in full sun. Germinations were generally carried out using punnets of jarrah forest topsoil in a glasshouse at a temperature of approximately 15oC -20oC. Two seedlings appeared after two weeks and were potted up. Narrow Phyllode is one of three variants of acacia acuminata, which includes the typical, small seed and narrow phyllode varieties. Scarification is required for Acacia acuminata.

We’ve included a link below to distinguish some of the physical characteristics of the different types of acacia acuminata. nature of the container used, so precise control is difficult to achieve. the range 60–90°C is often as effective as soaking at 100°C but there is less The key to germination is to soften or abrade the coating so that air and water can get through. A frequently-used technique is to immerse the seeds in 4–10 times their The species has good recruitment; many seedlings were observed. Pour just boiled water over the seeds and allow to soak for a few hours to overnight. stored for several months or years usually have less than 10% of seeds that Table 3     Recommended pre-sowing treatments for some dry-zone acacias. Fresh seeds with soft seed coats require no pretreatment. distributing the acid throughout the seeds by turning with a shovel, and then 1 litre of acid per 35 kg of seed), stored for several years. In Australia treatment of the seeds with boiling or hot water was practised out with simple equipment and at a low cost for materials as the acid is It grows commonly in the south-east of the beautiful state of Western Australia. 33:1137–1144. Experts on how to plant acacia seeds recommend as fresh a supply as possible for the best chances of success.
