Water thoroughly when the potting medium is almost dry. Chysis tricostata prefers consistently moist conditions during its active growth period but requires a drier rest period to encourage blooming.

Avoid waterlogged soil, which can lead to root rot.

Pruning is generally not required for Chysis tricostata beyond removing spent flower spikes and any dead or damaged pseudobulbs or leaves. This helps maintain plant health and prevents potential disease introduction.

Do this after flowering.

Propagation is typically done by division of mature clumps during repotting. Each division should have at least three healthy pseudobulbs and some viable roots.

Ensure good air circulation around the divisions to prevent rot.

Repot Chysis tricostata every 2-3 years, or when the potting medium begins to break down. Use a well-draining orchid mix, such as bark and perlite. Repot after flowering when new root growth is evident.
