Seed reproduction

Timing

In the propagation of Australian fir, the method of sowing and propagation is the most common, because the seedlings cultivated by sowing are more strong and vigorous, which is suitable for batch propagation, generally between July and August

Method

First break the seed coat of the just collected seed to promote its rooting and germination. Otherwise, if it is left in the soil for too long, it will be easy for the seed to rot. then sow the treated seed in the sand bed and sprinkle 2cm fine sand on it for coverage. Then we must control the temperature. Generally, the temperature should be maintained at about 25 ° and there should be relatively high humidity to ensure the demand for water

Precautions after germination

After this, it will begin to sprout after about 2 to 3 weeks, and the planted Australian fir will survive. Ensure sufficient sunshine and moisture in the early stage of germination

Cutting propagation

Selection of branches

Australian fir can be propagated by cutting, but when cutting, we must choose the main shaft or bare branch as the spike for planting, otherwise it is easy to cause the crown shape of the plant to be incorrect and can only grow horizontally, affecting the ornamental value

Breeding method

Generally, 2-3 sections in front of the strong branches that are easy to take root are cut for cuttings, and then the leaves are removed, soaked with clean water for one night, and then inserted into the sand bed with coarse sand or vermiculite as the matrix. When the humidity of the root is too high, it can't keep enough water. In this way, it can't be inserted into the root when the temperature is too high, so it can't meet the demand of water drainage

Germination time

Generally, new roots and buds will begin to grow in about three months. Generally, the survival rate of planting methods of planting seeds is relatively high, and the roots are also easy to germinate
