Additional Care Tips

Water regularly during the first year to establish. Once mature, it is very drought-tolerant and prefers dry conditions. Overwatering can lead to root rot.

Prune after flowering to shape the plant, remove dead or crossing branches, and encourage bushier growth. Avoid heavy pruning in late fall or winter to prevent frost damage.

Easily propagated from semi-hardwood cuttings taken in summer. Seeds can be sown in spring, but germination may be erratic and require stratification.

Repot container-grown plants every 2-3 years in spring, using a well-draining potting mix. Ensure the new pot has adequate drainage holes to prevent waterlogging.
