The breeding methods and precautions of Jihong Komatsu

The breeding method of Pinus jihongensis

Cuttings

For the propagation of Pinus kojira, use a healthy 5-6 cm cutting of the current year, remove the leaves 1 cm from the branch end, insert the cuttings 1 cm deep into the culture soil, compact the soil to make it firm, spray water to moisten the soil and cuttings, put them in a plastic bag, seal the bag, and place them in a semi-sunny place.

Open the bag frequently to check the situation inside. If the soil is dry, spray water to moisten it. As long as the branches and leaves are still green and upright, the plant will survive in two to three weeks. After the plant survives, open the bag and allow it to slowly adapt to the external environment. After a week, remove the plastic bag and carry out normal management.

Hydroponic root induction

Cut off 2~3 cm branches and insert them in pure perlite. Add water to the bottle, but the water should not soak the branches, just enough to reach the bottom of the branches. Then seal the bottle mouth, keep it moist, expose to scattered light, and occasionally open the bottle cap for ventilation.

It will take a week for the plant to take root. Put it in a pot immediately and water it every day. After one to two weeks, manage it normally and water it again when the soil surface is dry.

How to breed Jihong Komatsu

Watering requirements

When cultivating pine trees, be careful not to water them too much. The roots of pine trees are fleshy and will easily rot if water accumulates. Water them once every three to four days in spring and autumn. In summer, when the temperature is high and the water evaporates quickly, water them twice a day, once in the morning and once in the evening. In winter, when the temperature is low, you can water the plants once every seven to ten days. Use warm water at about 15°C. Do not use very cold water. Water at noon on a sunny day and make sure to water thoroughly.

Fertilization requirements

Apply liquid fertilizer every seven to ten days during the growing season in spring, summer and autumn. Liquid fertilizer is a high-concentration fertilizer made by adding animal and plant residues to water and fully fermenting and composting. Before use, it must be diluted with water in a ratio of 1:5~10.

Pruning methods

Pinus kumquats need to be pruned regularly. Cut back branches that are too long to leave two to three groups of leaves, remove dense branches, and wipe out root suckers. The pot needs to be repotted and the soil changed every year. In three years, the roots of the pine trees will reach a satisfactory level.
