Watering. Keep soil consistently moist but not waterlogged. Water more frequently during dry periods and reduce watering in winter. Mulching helps retain soil moisture.
Fertilizing. Feed with an acid-loving plant fertilizer in early spring and again after flowering. Avoid fertilizing late in the season to prevent new growth that could be damaged by frost.
Camellia japonica is a hardy shrub that prefers partial shade and well-drained acidic soil. It needs regular watering but dislikes waterlogged roots. Watch for common pests like scale insects and keep the soil moist but not soggy. Pruning after flowering helps maintain shape and encourages new growth.

Common problems
Overwatering can cause root rot, while too much sun may scorch leaves. Pests like scale insects and aphids can occasionally be a problem. Poor flowering may result from insufficient light or improper pruning timing.
Uses
Primarily grown as an ornamental plant for its attractive flowers and evergreen foliage. Often used in gardens, parks, and as container plants on balconies or patios.
Notes
Prune lightly after flowering to shape the plant and remove dead wood. Avoid heavy pruning which can reduce flowering. Protect from strong winds and late frosts. Repot young plants every 2-3 years if grown in containers.
