Intergeneric Orchid Spike Turning Brown After Aphids: Cut It Off

Post-Aphid Spike Care: When to Cut

Your intergeneric orchid had aphids, you treated it, the plant recovered but all flowers fell. The spike is drying/browning from the tip. Should you cut it?

Yes—Cut It Off

Most orchids (except some Phalaenopsis) bloom once per spike. Once flowers drop, the spike browns and dies back. Since yours is an intergeneric (not a Phal), cut the spike at the base.

Focus on Vegetative Growth

• Keep the plant growing well: light, water, fertilizer.
• It will bloom again next winter on a new spike.
• Monitor for recurring pests—aphids love tender new growth.

No need to leave a brown spike; it won't rebloom. Clean it up and care for the plant.
