Phalaenopsis Bottom Leaf Loss: Normal Aging vs. Root Problems

Bottom Leaf Loss = Normal

Oldest leaf yellows/drops naturally. Healthy Phals have 6+ leaves. If new leaf < previous size → problem (root rot, fertilizer, water).

Straight medium bark OR bark + 10–15% large perlite. Avoid moss/vermiculite unless chronic underwaterer.

Feed every watering at ¼ strength (weakly weekly) — no schedule memory needed. Or time-release. Flush monthly.

I was a hopeless newbie 40 years ago. Still learning. You're doing fine.
