Rhododendrons prefer consistently moist, well-drained soil. Water deeply during dry periods, especially in summer and when plants are establishing. Avoid waterlogged conditions, which can lead to root rot.

Mulching helps retain soil moisture and regulate temperature.

Prune rhododendrons immediately after flowering to shape the plant and remove dead, damaged, or crossing branches. Avoid heavy pruning, especially in late summer or fall, as this can remove next year's flower buds.

Aim for a natural, open form.

Rhododendrons can be propagated by layering in spring or summer, or by taking semi-hardwood cuttings in late summer. Seed propagation is possible but can result in significant variation from the parent plant and takes many years to flowering.

Container-grown rhododendrons typically require repotting every 2-3 years, or when they become root-bound. Repot in spring into a slightly larger container with well-draining, acidic potting mix.

Ensure the root ball is not overly disturbed.
