How to propagate Australian fir

Seed propagation

opportunity

When propagating Australian cedar, the most common method of seed propagation is seeding, because the seedlings cultivated by seeds are firmer and stronger, and grow particularly vigorously, which is suitable for batch propagation, usually between July and August.

method

First break the seed coat of the seeds just collected to promote their rooting and germination. Otherwise, if they are left in the soil for too long, the seeds will easily rot. Then sow the processed seeds in the sand bed and sprinkle 2 cm of fine sand on them to cover them. Then you must control the temperature. Generally, the temperature should be maintained at around 25°, and the humidity should be relatively high to ensure the moisture requirements.

Precautions after germination

After doing this, it will start to sprout after about 2 to 3 weeks, and the sown Australian fir will survive. Be sure to get enough sunlight and water during the early stages of germination.

Cutting propagation

Selection of branches

Australian cedar can be propagated by cuttings, but when doing so, we must choose the main axis or leggy branches as spikes for planting, otherwise it will easily cause the crown shape of the plant to be irregular and it can only grow horizontally, affecting its ornamental value.

Reproduction method

Generally, the first 2-3 nodes of strong branches that are easier to root are cut for cuttings, and then the leaves are removed. Then soak them in clean water for one night, and then insert them into a sand bed with coarse sand or vermiculite as the substrate. This will meet the nutritional needs of the roots and also have a good drainage function. When inserting it, the temperature must be kept at around 25°, not too high or too low. Sufficient water must also be provided to maintain a relatively high humidity in the air.

Germination time

Generally, new roots will begin to grow and sprouts will appear in about three months. The survival rate of the general planting method of cuttings is also relatively high, and the roots are also easy to sprout.
