Keep soil consistently moist but not waterlogged. Water deeply when the top inch of soil feels dry. Reduce watering slightly in winter, but do not allow the soil to dry out completely.

Proper drainage is crucial to prevent root rot, especially in sandy or well-draining media.

Prune after flowering to maintain shape and remove any dead, damaged, or crossing branches. Light pruning can encourage bushier growth. Avoid heavy pruning, as it can reduce the number of blooms in the following season.

Aim for natural form rather than drastic shaping.

Sand myrtle can be propagated by semi-hardwood cuttings taken in late summer or fall. Use a rooting hormone and plant in a well-draining, sterile potting mix.

Keep the cuttings moist and in a humid environment until roots form. It can also be propagated by seed, but this is a slower process.

Repot only when necessary, typically every 2-3 years, or when the plant becomes root-bound. Use a well-draining, acidic potting mix. Repot in early spring before new growth begins.

Handle the root ball gently to avoid disturbing the roots too much, as they can be sensitive.
