watering
Japanese black pine (Pinus thunbergii) should be watered once or twice weekly. In warmer months, increase watering frequency as necessary. Water deeply to ensure that the soil is fully saturated. Wait until the top few inches of soil in the pot begin to feel dry before watering again. During winter months, reduce watering frequency and water only when the soil is completely dry.
sunlight
Japanese black pine needs full sunlight or at least 6 hours of strong direct sunlight each day. It is best for this plant species to receive direct sunlight in the morning and afternoon to maximize photosynthesis and growth. Japanese black pine can tolerate unfiltered sunlight during the peak heat hours of the day, but the plant may suffer from burn damage due to the intensity.
pruning
Pruning should be done early in the spring for Japanese black pine. Pruning should involve thinning the tree. Start by removing dead, diseased, and crossing branches. Then take out thin or weak branches to open up the tree's structure. Aim to achieve an open, vase-shaped silhouette. If large branch removal is necessary, prune so the wound is minimal and the bark edge remains intact. Finally, cut back overly long branches in order to shape the tree and create a balanced appearance.
