When is the best time to repot black pine? Time and precautions for repotting

Time to repot black pine

Black pine needs to be repotted. Timely repotting can meet the needs of root growth, and the nutrients in the soil can also promote vigorous growth of the plant. Therefore, repotting is relatively important for the growth of black pine. The pot can be repotted every 1-2 years. Black pine can be repotted in spring from February to May and in autumn from October to November, preferably in spring.

How to repot black pine

1. Stop watering the black pine before repotting. The slightly dry soil makes it easier to fall out of the pot. After removing the black pine from the pot, shake off about half of the old soil in the original pot, and then prune the roots. All the old, weak, dead roots, thin roots and rotten roots can be cut off. Some roots that have grown too long can also be trimmed and placed in a well-ventilated place to dry the wounds for later use.

2. When planting black pine in pots, 30-50% coarse sand should be added to the pot. This can effectively improve the looseness, air permeability and water permeability of the potting soil. After re-potting and settling, you only need to keep the potting soil moist, because black pine likes dryness and is resistant to barrenness. Do not over-water and cause the soil to be too wet.

Notes on repotting black pine

Be careful when repotting black pine and do not damage the roots, otherwise it will affect its subsequent growth. In addition, the plant grows slowly after repotting and has little demand for water and fertilizer. Therefore, control watering and stop fertilizing. Wait until it adapts to the new environment and grows new roots before maintaining it normally.
