How long does it take for black pine cuttings to take root?

Rooting time of black pine cuttings

The best time to take black pine cuttings is in spring when the temperature is suitable. The suitable temperature in April and May is conducive to the growth and rooting of black pine, thereby improving the survival rate of cuttings.

Black pine usually takes root in about 25-35 days. If cut in the correct way, it will sprout in a week and form healing tissue and start to take root in half a month.

In addition, after the black pine is grafted, the temperature should be controlled between 18℃ and 28℃, and suitable light conditions should be provided. Leaves will begin to grow after 20 days.

Black pine cutting rooting method

1. Select branches: Do not use perennial old branches for black pine cuttings, as their activity is poor and the survival rate is very low. It is best to use one-year-old branches, which are easier to survive.

2. Choose the time: In spring, the germination ability of black pine is the strongest, and the gradually rising temperature is conducive to the growth of its root system. The time for cuttings depends on the environmental conditions of the planting site. It is best to choose April or May.

3. Soil selection: It is best to choose soil with good water retention performance and good air permeability and looseness. You can choose river sand, vermiculite, coconut bran, etc. It needs to be disinfected before use.

4. Carry out cuttings: Put the flower soil in a breathable flowerpot and water it until the soil is wet. Do not water it too much to cause water accumulation. After treatment, you can insert the cuttings into the soil and maintain it in a well-ventilated environment, and slowly wait for it to take root and sprout.

Management of black pine cuttings

1. After the black pine cuttings have taken root, they can be exposed to the sun. They can be exposed to the sun appropriately according to the situation, but they should not be exposed to the scorching sun to prevent the leaves from wilting.

2. Fertilizer can be applied after the black pine cuttings have taken root. Phosphorus fertilizer and nitrogen fertilizer can be applied after rooting. Black pine does not like large amounts of fertilizer. If concentrated fertilizer is applied, it will cause excessive growth of branches and leaves, affecting the overall shape.

3. After cuttings, black pine should generally be watered thoroughly once, then placed in a cool place, spray water on the leaves every day to increase the humidity, and water the potting soil when it is dry.
