Reviving a Struggling Phalaenopsis: Repotting, Root Rot, and Watering Fixes

Your orchid (likely Phalaenopsis) was doing fine in Utah's variable weather, but now flowers are wilting, leaves have died, and two flowers are gone. You water when the mix looks dry.

The Real Culprit: Broken-Down Potting Mix

Most beginners don't realize orchids need annual repotting in a special, airy mix. Old mix breaks down into soil-like material that stays wet inside even when the surface looks dry. This suffocates roots, causing rot—and leaf loss.

Immediate Action Plan

1. Buy fresh orchid potting mix (bark-based, not soil).
2. Unpot the plant; wash all roots thoroughly.
3. Cut away all mushy (dead) roots—healthy roots are firm.
4. Repot in the smallest pot that fits the remaining roots.
5. Water weekly after repotting; mist aerial roots if humidity is low.

Watering Correctly

Don't water by surface appearance. In fresh mix, water when the mix is barely moist a few inches down. In degraded mix, the surface dries while the center stays soggy—a root rot trap.

Recovery Expectations

Sickly leaves will drop. Focus on growing new roots first; new leaves will follow. Phalaenopsis flowers last 2–4 weeks naturally—don't panic over spent blooms. Keep indoors in an east window (65–85°F), avoid temperature swings.
