Phalaenopsis Regrowth: Handling Old Spikes, Repotting & Light Needs

A grower with three Phalaenopsis plants describes two finished blooms: one spike turned yellow-brown with green at the base; the other turned completely black. The plant with the black spike has only two leaves left. They ask how to handle the spikes and save the struggling plant.

Understanding Flower Spikes

What you call "stems" are old flower spikes. Genetically, some Phalaenopsis shed spikes (they die back)—these can be cut off; they won't regrow. Other types retain green spikes and may rebloom from them. This is genetic, not cultural.

Saving the Two-Leaf Plant

• Repot after flowering in fresh orchid mix. Use pots with abundant drainage; don't let pots sit in water.
• Remove mushy roots (dead); healthy roots are firm and green when wet.
• Light: East-facing window preferred. Deep green leaves = insufficient light for rebloom.
• Temperature: 65–85°F ideal; brief excursions outside this range are tolerated.

A new spike should emerge in spring on a healthy plant.
