It only takes one growth cycle and takes 6~ 12 months to finalize the design.

When the black pine is shaped, the pine needles sprouting from the middle and lower parts of the seedlings are first removed. Remove the pot soil to expose the upper root system, and fix the aluminum wire in the pot soil. Or the aluminum wire passes through the drain at the bottom of the flowerpot. After the aluminum wire passes through the bottom of the flowerpot, it bends a small circle at one end near the drain, inserts a wooden stick to fix it, or passes through another drain, and is wound and fixed for many times.
