Phalaenopsis Root Rot After Peat Moss Repot: Rescue Steps

Your Phalaenopsis (1 year, 7 leaves, healthy) got surface fungus. You repotted in peat moss + Lowe's commercial mix. One leaf wilted; you repotted again, found most roots dead (thick inner core with spongy outer layer). Only 3–4 viable roots left. New leaf is soft. You're worried it will die.

Peat Moss Is the Problem

Peat-based mixes retain water too long, causing rapid root rot. Orchids need airy, chunky mixes (bark, perlite, charcoal).

Immediate Correction

1. Get orchid bark mix (bark, perlite, charcoal) or straight medium bark.
2. Repot in SMALLER pot (fits few roots).
3. Water only when mix is barely moist.
4. Warm, humid (>50%), barely moist conditions.
5. Create mini-greenhouse: clear plastic bag over plant to boost humidity.

New Leaf May Not Stiffen—Focus on Roots

Root regeneration takes a month+. Without roots, leaves can't hydrate. The soft leaf may not recover, but new roots will support future leaves.
