Cattleya Root & Rhizome Wrinkling: Rest Periods, Humidity & Repotting

Respect the Rest Period

Cattleyas rest after growth completion. Watering during rest = rot. Water/feed ONLY during active growth. Mist occasionally during rest.

Humidity for Aerial Roots

High humidity always. Humidity tray (pebbles + water, pot above) extends humid zone beyond pot—prevents aerial root desiccation.

Pot Roots Matter Most

Most roots are inside the pot. Old mix compacts → less air + holds water → rot. Annual repotting at growth start in fresh mix = healthy root zone. Inspect/trim dead roots each time.

Your Routine Check

• Rain water = excellent.
• Fertilizer: ¼ tsp/1.25 gal = very weak (good).
• Water first, then fertilize = prevents burn (good).
• Tan dying roots = likely old mix breakdown, not fertilizer.

Action Items

1. Add humidity trays.
2. Repot annually in fresh bark at new growth.
3. Water/feed only in active growth.
4. Mist only during rest.

Your attention to detail is great—just sync with the plant's natural cycle!
