Azalea with Yellow Lower Leaves: Root or pH Issue?

Normal winter yellowing on azaleas shows a tuft of green at branch tips with yellow interior leaves. Your plant has yellowing concentrated in one section—indicating a localized root problem or pH imbalance.

Likely Causes & Fixes

• Soggy soil: Dig out soil under the yellow section; replace with high-quality planting mix. Water in with half-strength houseplant fertilizer.
• Dog urine ("canine canker"): If a dog repeatedly visits that spot, salts burn roots. Fence it off.

Compare with photos of normal winter yellowing to confirm the difference.
