watering

Japanese sweetspire needs regular watering, especially during its growing season (from March to October). During this time, water the plant thoroughly at least once a week, allowing the soil to dry out slightly between waterings. For best results, water early in the day and water deeply to help encourage deep root growth. During the winter months, reduce watering and make sure the area does not become waterlogged. Do not let water stand in the soil, as this can cause root rot.

sunlight

Japanese sweetspire plants should receive full sunlight for at least 6 to 8 hours per day. It is best to provide morning sun because they can get too hot in scorching afternoon sun. The plant does best when placed in an area with morning sun and afternoon shade. Additionally, this species thrives in areas with bright indirect light. However, prolonged exposure to direct sunlight for several weeks in a row can cause the leaves to scorch.

pruning

Japanese sweetspire should be pruned in late winter or very early spring, before new growth begins. Pruning should be done selectively to maintain the shrub’s natural form and ensure good air circulation. Remove dead, damaged, or diseased stems and thin out overcrowded branches. Although this species does not require extensive pruning, it can be trimmed lightly to shape as desired.
