Planting and Management of Pinus elliottii

Propagation method: Pinus elliottii can be propagated by seedlings or sown in early spring. Lighting: pine of the four seasons can withstand severe cold and drought. It can be maintained in a sunny place outdoors all the year round and properly shaded in summer. Watering: like to dry, the soil can be thoroughly watered. Fertilization: the amount of fertilizer required is small, and a small amount of thin fertilizer and decomposed cake residue water can be applied during the breeding period. Pruning: culture 3-5 years need to change the basin soil, pruning terminal buds and growing disorderly branches.

I. seed selection and sowing

1. Four-season pine can generally use seedlings to reproduce, and its germination rate will be relatively high, which is conducive to the vigorous growth of seedlings. You can take a cone in October, put the cone in the sun to dry, and then take out seeds from the cone. Select strong, disease-free seeds and put them in a bag to wait for sowing.

2. When sowing in early spring, the seeds can germinate at the end of April, and the seedlings can grow to about 10-15cm.

Second, sufficient light

The four seasons pine is more resistant to cold and drought, so it can be maintained in a place where the sun is fully illuminated outdoors throughout the year, and it is also necessary to ensure that the surrounding ventilation is good. Bonsai smaller plants need proper shade in summer to avoid hot sun exposure. in winter, it can be put outside for the winter, or it can be moved to the indoor for the winter, the indoor temperature should not be too high, and then move to outdoor maintenance after Ching Ming Festival.

3. Proper watering

Four seasons pine is suitable for planting in dry soil, during which there is no stagnant water in the basin, the soil can be drenched thoroughly after irrigation and sealing, and the soil should be drained in time when it rains to avoid excessive water accumulation and root rot. Proper control of watering water in spring, autumn and winter is helpful to promote the robust growth of branches and make the plants more ornamental, but when the summer weather is hot, it is necessary to spray water to the plants regularly.

IV. Fertilization in soil

In the growth process of four-season pine, the demand for fertilizer is not very large, because the ability of four-season pine to tolerate barren is relatively strong, the nutrients in the planted soil are insufficient, and it can also grow normally in a short time. Generally, the branches grow short and thick, and the needles are relatively short. During this period, a small amount of thin fertilizer and decomposed cake residue water can be applied properly.

5. Pruning branches

After growing for 3-4 years, the terminal buds should be trimmed in time. When the new buds are extracted and the needles have not yet grown, the terminal buds can be cut off by half. If you do not want the branches of Pinus elliottii to grow too high, all the terminal buds can be removed. When the pine enters the dormant period, the fragile and messy branches can be trimmed, which is helpful to improve the ornamental quality.

VI. Change the basin soil

Potted four-season pine needs to change the pot soil every 3-5 years, usually in February-March, when replacing the pot soil, you need to pour out all the old pot soil, and then change to the new soil, during the period to properly trim the rhizome of the four seasons pine, and according to the size of the plant, select a suitable flowerpot, and then fill it with new soil, and plant the four seasons pine into the new flowerpot.
