Melaleuca - Propagation


Melaleucas can be propagated by either seed or cuttings. However, to maintain desirable characteristics of a particular plant, vegetative propagation (eg. cuttings) must be used. This also applies to propagation of named cultivars.

After flowering, melaleucas produce seed capsules either in rows along the branches similar to those of Callistemon, or in more or less globular shaped clusters. In the majority of cases the seed remains within the capsules indefinitely and can easily be collected at any time.

In the case of species which retain the seed indefinitely on the plant, the capsules need to collected and placed in an open container in a warm position until the fine seed is released. This should occur in 2-3 days. For best results, the capsules should be at least 12 month's old (ie. the most recently formed capsules are best avoided). With those species which release the ripe seed annually, the plant needs to be kept under observation and seed capsules collected when the capsules commence to open.

Germination of the seed of Melaleuca species is usually quite easy by normal seed raising methods. No special pretreatment is needed. Germination should occur in 14 to 30 days, depending on the species.

A common method used for germination of Melaleuca and related plants is the "bog method" where the pot containing the seeds is placed into a saucer of water until germination occurs. This results in moisture reaching the seeds by capillary action and ensures that the seeds do not dry out.

Propagation of Melaleucas from cuttings is generally a reliable method. Cuttings about 75-100 mm in length with the leaves carefully removed from the lower half to two-thirds seem to be satisfactory. "Wounding" the lower stem by removing a sliver of bark and treating with a "root promoting" hormone both seem to improve the success rate.
