Management of the growth cycle of black pine

Temperature management: Black pine is not cold-resistant and is suitable for growing in warm and humid marine climate areas. The maintenance temperature should be controlled between 15 degrees and 30 degrees.

Fertilization management: It is generally believed that lean soil is best for growing pine trees. One should try to control fertilizer and water so that the supply of fertilizer and water just maintains the minimum survival of black pine. This approach may be helpful in preventing the pine needles from growing too long. During the bud cutting period, pine trees should be given more topdressing. It is foolish to cut the buds of weak seedlings, which will hinder the next germination.
