Water thoroughly when the potting medium is nearly dry, typically once every 7-10 days during active growth. Reduce watering significantly during the winter dormancy period, allowing the pseudobulbs to slightly shrivel.

Avoid waterlogged conditions, which can lead to root rot.

Pruning is generally not required for Cattleya lawrenceana beyond removing spent flower spikes and old, decaying pseudobulbs or leaves. Cut back flower spikes after blooming to prevent disease.

Ensure cuts are clean to minimize stress on the plant.

Propagation is primarily done through division.

When the plant becomes too large for its pot, typically every 2-3 years, divide it into sections, ensuring each section has at least three healthy pseudobulbs and good root mass. Replant immediately into fresh medium.

Repot Cattleya lawrenceana every 2-3 years, or when the potting medium begins to decompose. Use a well-draining orchid mix, such as bark or a sphagnum moss blend.

Repot after flowering, when new root growth is evident, to minimize transplant shock.
