Grandleaf Seagrape prefers consistently moist soil but can tolerate short dry spells once established. Water deeply when the top 2-3 cm of soil feels dry.

Reduce watering during cooler winter months, but avoid letting the soil dry out completely, especially for container-grown plants.

Pruning is generally minimal for Grandleaf Seagrape, primarily focused on removing dead, damaged, or crossing branches. Light pruning can be done after flowering to shape the plant or encourage bushier growth.

Avoid heavy pruning, as it can reduce future fruit production.

Grandleaf Seagrape can be propagated from seeds, though germination can be slow and erratic. Cuttings are also a viable method; take semi-hardwood cuttings in summer and root them in a well-draining medium.

Seed propagation is more common for large-scale cultivation.

Young plants may require repotting every 1-2 years to accommodate their growth. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Established plants in the ground rarely need repotting, but container specimens benefit from fresh soil periodically.
