Sowing and propagation of hawkthorn thistle

The seeds of hawkthorn thistle are relatively small, and the sowing needs to be more meticulous. Generally, it is suitable to sow in the greenhouse in early February or in the open field in early April. The cultivation soil is suitable for half of agricultural fertilizer and half of garden soil, mixed with a small amount of rotten leaf soil, mixed evenly and screened. Put the culture soil into a suitable container, gently compact the substrate, and then pour water. After the water seeps in, the seeds can be evenly sown on the wet soil. It should be noted that the soil covering depth should not be too thick, and it is better to cover the seeds tightly. Then keep the basin soil moist. The seedlings will emerge in about 10 days. When the seedlings grow 2 pairs of true leaves, they can be divided. Note that the seeds of huoxiangji are small, so the seedlings grow slowly

Cutting propagation of hawkthorn thistle

The advantage of cutting propagation is that it can promote the early formation and early flowering of huoxiangji plants. Besides the low temperature in winter, cutting can be carried out in other growing seasons, and the survival rate is relatively high. First of all, prepare a healthy large mother plant, put it in the greenhouse in winter, select the robust branches of huoxiangji in early spring, and keep 2-4 true leaves. The length of the branch is about 5-6cm, and the cutting opening is located under the node, which can be inserted with cutting. The cutting depth is about 1 / 3-1 / 2 of the cutting length. In high temperature season, cuttings need to be placed in a cool and ventilated place to prevent damage caused by high temperature and sunlight. Generally, you can take root in about 10 days, and then you can divide seedlings< span>
