Fertilizing

Feed your Tamarix bonsai every two weeks throughout the growing season with a balanced fertilizer to support healthy growth and abundant flowering. For best results, use a general-purpose bonsai fertilizer in spring and early summer, then switch to a lower nitrogen formula in late summer to help the tree prepare for winter dormancy. While Tamarix is not a heavy feeder, consistent fertilization helps maintain the delicate foliage and promotes the development of its characteristic feathery appearance.

Placement

Position your Tamarix bonsai in full sun but provide protection from intense midday sun during summer months to prevent leaf scorch. While these trees are highly adaptable to different conditions, they thrive best outdoors where they can receive adequate light and airflow. During winter, protect the tree when temperatures drop below -5°C (23°F), though some frost protection may be needed depending on your climate. These trees are particularly well-suited to coastal areas due to their natural salt tolerance, making them excellent choices for seaside gardens.

Pruning

Pruning requirements vary depending on whether you have a spring or summer-flowering variety. For spring-flowering Tamarix, prune immediately after the flowers fade to avoid removing next year's blooms. Summer-flowering varieties should be pruned in March before new shoots develop. When styling, many Tamarix bonsai are designed with weeping foliage, which requires wiring growth downwards as it extends.

To maintain the tree's shape and health, remove any crossing or rubbing branches to improve air circulation and reduce the risk of disease. Hard pruning is essential each year to prevent branches from becoming tangled and maintain the desired form. When creating a more tree-like shape, prune between October and March by carefully removing the lowermost side branches, always leaving the branch collar intact to ensure proper healing.

Repotting

Repot your Tamarix bonsai in mid-spring as buds begin to extend, using a well-draining soil mixture. The soil should be neutral to acidic with excellent drainage capabilities to prevent root rot. When repotting, gently prune the roots but avoid aggressive root reduction as this can stress the tree. Add a layer of mulch around the base after repotting to help retain moisture and suppress weed growth. Consider using a mixture of compost and perlite to ensure proper drainage while maintaining adequate moisture retention.

Watering

Tamarix requires careful attention to watering as it is prone to root rot in overly wet conditions. Allow the soil to dry slightly between waterings, but maintain regular irrigation during dry periods. These trees naturally grow in coastal and arid regions, making them somewhat drought-tolerant once established. However, consistent moisture is important during the growing season and after repotting. Water thoroughly when needed, but ensure the soil drains well and avoid waterlogged conditions. Use a well-draining soil mix and monitor moisture levels carefully, especially during periods of reduced growth.
