What soil should be used for five-needle pine?

Five needles pine is born in a dry place on the mountainside, which can resist shade, moisture and heat. The requirements for soil are not strict, except alkaline soil, and slightly acidic grayish yellow soil is the most suitable.

Generally speaking, the slightly acidic soil with fertile and loose soil, good permeability and pH value of 5.5 ~ 6.0 is better, and the natural black mountain mud is better in the basin soil. Humus soil and compost soil can also be mixed to prepare culture soil. This kind of cultivated soil has suitable pH value and good water and fertilizer retention performance, which is beneficial to the growth of American ginseng.

Matters needing attention in planting five needles pine

Moderate light: Pinus pentaphylla is a neutral plant, which can grow in sunny or cool places. However, when it is kept in a sunny and ventilated place, the needles will grow green and strong. In places with insufficient light and hot weather, needles grow thin and wither easily. It is best to give five-needle pine more than 5-6 hours of light every day and maintain good ventilation conditions. However, in the hot noon in midsummer, in order to prevent needles from being burned by excessive sun exposure, measures such as shading can be taken, and they can be fully exposed to the sun at other times.

Control watering: the watering of the five-needle pine bonsai should be moderate, and the pine trees are dry and wet, indicating that the five-needle pine is dry. When the temperature is high in summer, the soil in the basin dries easily. Generally, it is watered once in the morning and evening, depending on the wet and dry conditions of the basin soil. When there is a shower, cover the rain in time to avoid the loss of nutrients in the soil.
