Troubleshooting
Satsuki Azalea problems — and how to fix them
Satsuki Azalea (Rhododendron indicum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Lime-induced chlorosis
Hard water or alkaline soil yellows the leaves between green veins. Use ericaceous soil, soft water and an acidic feed to restore colour.
Drying out
Shallow roots wilt quickly if the soil dries, sometimes fatally. Keep the substrate consistently moist, especially in summer heat.
Root rot from waterlogging
Dense, water-retentive soil rots the fine roots. Use a free-draining ericaceous mix like kanuma and avoid standing water.
Lace bugs and vine weevil
Lace bugs stipple and bronze the leaves while vine weevil larvae damage roots. Inspect foliage and root zone, and treat promptly.
