The black pine is a hardy, versatile plant and ideal as a bonsai tree. The black pine is native to Japan and prefers cooler climates. It grows slowly and takes a long time to form into a bonsai tree, so it is better for those with a lot of experience as bonsai gardeners. Ideally, the black pine bonsai should be formed at an early age, with a particular style in mind.
Plant the black pine bonsai tree in soil that is 50 percent akadama and 50 percent pumice.
Water the black pine sparingly to keep the black pine bonsai moist but not too damp. Allow the soil to dry out between watering.
Expose the black pine bonsai tree to full sun. Cover the pot to protect the roots from the heat. Rotate the plant daily so the sun touches all parts of the foliage.
Prune the tree in the spring. Place the tree in the shade for a few weeks after pruning so the roots have a chance to take hold. Pinch weak buds off at the end of spring. Leave only the strongest and healthiest buds.
Re-pot the black pine bonsai in the spring in a pot that is large enough to accommodate the roots. Gently rearrange the roots when re-potting. Put the pot in partial shade for a few weeks after re-potting.
