Seed Information

Seed Collection

Most acacias are readily propagated by seed. Monitor carefully as seeds are shed on maturity. Pick pods just as they start to dry and change colour. Spread on sheets. Sieve to isolate.

Seed Treatment Method

Hot Water Hot water is used to soften the hard seed case of some species. This replicates the weathering process. Pour hot (not boiling) water over the seeds and allow them to soak for 4-12 hours.

Seed Storage Life

Long

Germination Time

10-30 days

Cutting & Division Information

Cuttings are possible with “phyllode bearing” acacias, more so than with “feathery leaved” species.
