Yellow Leaves on Lilies in Louisiana Heat: Drainage Is Key

Louisiana gardener's yellow lilies had pale green/yellow leaves despite full sun, water, and Miracle-Gro. Hot, humid weather.

Diagnosis

With sun, water, and fertilizer covered, poorly draining soil is the likely culprit. Soggy roots die → leaves yellow.

Fix

1. Dig up a few plants; check roots. Brown/mushy = rot.
2. Replant in amended soil: 1/3 fine mulch + 2/3 potting soil, mixed 50/50 with native soil to 12 inches deep.
3. Do not layer—mix thoroughly.

Good drainage is non-negotiable in humid, rainy climates.
