New Phalaenopsis Dying: Root Rot from Retail Neglect

Gift Phalaenopsis with Root Rot: Not Your Fault

Jen got Phalaenopsis 1 month ago as gift, now dying. Instructions: water every 21 days or when soil nearly dry. Hasn't watered (still moist), but leaves yellowing/shriveling. Bottom two leaves gone, top leaf yellow/shriveled, last green leaf yellowing at base. Moved from west window (blinds closed) to room with south/east/west windows (no direct sun)—third leaf yellowed then. Plant in full bloom, flowers healthy.

Expert Response

Jen, not your fault—plant was in poor shape when purchased. Root rot. Many retailers don't realize buyers want to grow orchids long-term. Garden center staff lack orchid knowledge. Home Depot orchids floating in water; staff said supplier told them to water twice daily. Home Depot accepts returns within 30 days with receipt. You have at least one healthy leaf—chance to learn. If you want to save it: get hobby bag of orchid mix (fir bark). Need 4-5 inch plastic pot with drainage. Soak mix while unpotting (can wait until flowering ends, but grow dry). Rinse roots, discard old mix, remove collapsed roots (healthy firm, green when wet). Collapsed roots = main demise reason. If at least one healthy root, place in new pot, add wet mix where it can drain. Add mix to base of good leaf, drain overnight. Wait one week, then water weekly. Orchids need open mix, repot after each flowering. When flowering ends, cut spike above node. Yellow leaves will fall. With proper mix/environment, plant grows new roots and leaves.
