Rescuing Wave Petunias from Root Rot: Watering Frequency and Drainage Fixes

Brown roots/stems at soil line = crown/root rot. Causes: overwatering (daily watering is too much), poor container drainage, or fertilizer burn.

Water deeply but infrequently: sprinkler 40 min every 4–6 days (adjust for heat/soil).
Containers: water daily only if they drain fully. Learn pot weight when wet vs. dry.
Water morning, not evening. Avoid wet foliage overnight.
Fertilize only well-watered plants, at label strength.
