What if the leaves of Penglai pine turn yellow?

1. Lighting

Lighting is not only a very important element for flowers, but also a science. Insufficient or excessive light may affect the growth of flowers. Penglai pine is a sunny flower, if it is placed indoors for a long time, it will yellowed leaves if it cannot come into contact with the sun. Once this symptom is found in the penglai pine placed in the dark, it should be moved to the sunny ventilation place immediately.

Penglai pine should be watered when the soil surface in the basin is dry, and must be watered thoroughly, can not cause too much waterlogging, nor can it be stopped only half of it.

How to water Penglai pine (how often)

1. Growth period

The outside plant should be fully watered during the growing season, and the temperature decreases after entering autumn, so we should gradually reduce the watering of it at this time. In order to make its branches and leaves flourish, we can apply more nitrogen and potash fertilizer, which can be applied once in about 15 days. At the beginning, during the growing season of spring and summer, we should apply fertilizer every half a month, mainly nitrogen and potassium. Usually, when planting, we should also pay attention to the fact that there is no stagnant water in the basin soil, otherwise it will cause rotten roots, yellow leaves and other phenomena.

2. Mature period

After it is potted for 2-3 years, we have to change the pot in the spring season. In order to cut off its dense plants and long branches, the purpose is to facilitate the history of its good ventilation and light transmission. In its growing period, we can cut off its dead branches and yellow leaves at any time to make the plant symmetrical and beautiful. The most important thing is that during the two seasons of spring and summer, it still needs to pay attention to keeping them in an environment with sufficient water, because Penglai pine is a warm and humid growing environment, and it is afraid of strong light and low temperature. so we must pay attention to shade in summer, but we need plenty of sunshine in winter.

How to raise Penglai pine

1. Temperature

Penglai pine can grow at a temperature of more than 15 ℃, so be careful not to be too low in winter, otherwise it will stop growing, and the suitable temperature for growth is between 20 ℃ and 30 ℃.

2. Lighting

Penglai pine should be cultured in semi-shade, especially in summer to avoid direct sunlight, otherwise it will cause the leaves to be scorched due to lack of water. At the same time, pay attention to ventilation.

3. Moisture

In the vigorous growth period of Penglai pine, sufficient water should be given, but it can not lead to stagnant water in the basin, otherwise it will cause hypoxia and death in the roots. In slow-growing seasons such as winter, there is no need for frequent watering, just to keep the basin soil moist.

4. Fertilizer

Fertilization should form the law of fertilization from January to January, especially nitrogen and potassium fertilizer is the most suitable, which can promote the growth of Penglai pine.

Propagation method of Penglai pine

1. Sowing method

For the seeds of Penglai pine, if the sowing method is to be used, the seeds can not be sowed directly in the soil, and some treatments should be carried out before sowing. Because the seed coat of Penglai pine is relatively thick and it is difficult to germinate, it is necessary to accelerate germination before sowing. Now soak the seeds in cold water for three days to a week, then mix the seeds with hydrated lime and wait until the seed coat is cracked before sowing. The sown soil should be slightly acidic, with good drainage and adequate base fertilizer.

2. Split-plant method

At the same time, we can also choose plant division method to propagate. This method is suitable for changing seasons in spring and summer. First of all, remove the old plant from the basin, under the premise of not damaging the main root, cut off some underground roots, ensure that there are 3-5 branches on each clump of roots, and then put these roots into the culture soil for propagation.

Penglai pine likes a warm, humid and semi-shady growth environment, so during its growth period, it must be given sufficient water. Of course, we can not let the pelvic floor stagnant water, these conditions are one of the main factors affecting the yellowing of Penglai pine leaves.
