Harvest Tips
This is an ornamental orchid grown for flowers, not harvested for food or material. Cut flower sprays with sharp, sterile pruners when 2-3 flowers are open and remaining buds show color; they last 2-3 weeks in a vase. Remove spent flowers gently to extend bloom; allow spikes to dry and drop naturally before removal, or prune once all flowers have fallen.
