Cattleya Bud Blast: Why Two of Four Pods Failed

Partial Bud Loss on a Mature Cattleya

A 5-year-old Theresa Winkelmann Cattleya produced 4 buds; 2 opened, 2 blasted (yellowed, dropped). The failed buds were on the opposite side of the pot.

Possible Causes

• Colder microclimate near window on that side.
• Water left on those buds overnight → fungus.
• Plant couldn't support 4 flowers energetically.

Repotting Timing

Unless plant is struggling, wait until spring. Gather supplies now.

Investigate the microclimate difference. Next year, equalize conditions.
