Key points of five-needle pine maintenance

Five-needle pine is suitable to grow in loose, fertile and slightly acidic soil with good drainage. If the needle is too alkaline, the needles will turn yellow and fall off, so it is better to use natural mountain soil in basin soil. According to the proportion of basin soil, 3 parts of rotten leaf soil, 5 parts of garden soil, 1 part of compost and 1 part of sandy soil were mixed into nutrient soil. Generally, the basin should be changed every 2 to 3 years, and the time should be from February to March or from September to October.

Five-needle pine is a positive tree species, spring, autumn and winter should be kept in a sunny place, the needles are short and strong, the leaves are green, on the contrary, the needles are thin and easy to wither and yellow. But in the hot summer, the hot sun should be avoided around noon so as not to cause the needles to scorch. Spring and autumn are the growing season of five-needle pine, so it is necessary to keep the basin soil moist and promote the growth of branches and leaves. The slow growth of five-needle pine in summer has entered a dormant period, but the water evaporation is large, watering every morning and spraying water to the leaves in the evening. Control watering in winter and maintain its lowest temperature. After the five-needle pine is formed, do not apply too much fertilizer, otherwise it is easy to hurt the root.

Five-needle pine potted plants should choose a dry and ventilated environment, too wet and too shady are disadvantageous to its growth. Watering should be appropriate, usually once a day in spring and autumn, twice a day in summer, and once a few days in winter. At the same time, we should pay attention to the flexible control of weather changes. It is better to pour it with natural water. If you use tap water, you can keep it in the tank for a few days and then pour it.

Five-needle pine does not require high fertility, fertilization should not be too much and too thick, too much fertilization will make shoots grow, needles longer, hindering ornamental value. Generally speaking, only two fertilizers are applied during the growth period of spring and autumn, organic liquid fertilizer (cake fertilizer and water) is applied before germination or after thick leaves in spring, and thicker fertilization can be applied appropriately in autumn to promote robust growth. Stop fertilizing after October.

Attention should be paid to the following three points in the maintenance process:

1, watering too frequently, or more Rain Water in June every year, the basin soil is often too wet, coupled with poor drainage and stagnant water in the basin, causing anoxia in the soil, causing rotten roots and yellowing needles.

2. In the hot summer, the water evaporates quickly and is not watered enough, which will cause the needles to scorch. If the hot sun exposure, the basin soil is too dry, the five-needle pine will also appear top needle tip scorched, if continue to lack of water, the plant will eventually die.

3. The five-needle pine has been put indoors for a long time, lack of light and air, which violates the habit that the five-needle pine should receive light outdoors, or suddenly move to the outdoor to encounter exposure, the same will happen. In order to avoid the withering and yellowing of five-needle pine leaves, corresponding prevention and rescue measures should be taken according to the above reasons.
