1、 Sowing and propagation

The propagation of Pinus koraiensis plants is mostly carried out by sowing, and the specific time is in spring. Choose the soil with good ventilation and drainage as the substrate, and the seeds should be healthy and full, so the budding rate will be higher. The sowing method is very simple. Directly sprinkle the seeds on the soil surface, cover them with thin soil, water them appropriately, and then place them in a ventilated place. Small buds can grow in about half a month. Usually, we should often observe the growth. The seedlings grow stably and can be transplanted and planted after growing a few young leaves

2、 Cutting propagation

1. Cutting time: cedar plants can also be propagated by cutting. The time is selected from March to may in spring or September to November in autumn. The climate in these two time periods is warm and suitable, which is more conducive to rooting

2. Cutting treatment: when cutting, the cutting should be strong, not too long, and the length should be controlled at about 10 cm. It's best to pay attention to more details. In addition, prepare breathable and loose matrix, and disinfect it before reuse

3. Cutting into soil: cutting can be inserted into soil after the cuttings are processed and the required matrix is prepared. Pay attention to the depth of cutting, not too deep. The depth of 35 cm into the soil is OK. After cutting, it should be watered and moistened, and more ventilation should be provided, so that it can take root in a short time, which proves that the cutting has survived
