Troubleshooting
Summer Impala Lily problems — and how to fix them
Summer Impala Lily (Adenium swazicum) 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.
Root rot from overwatering
The most common cause of death, especially in winter. Ensure the soil dries fully between waterings; never allow the pot to sit in water. If the base of the stem becomes soft or mushy, remove all wet soil, allow roots to air-dry for several days, then repot in fresh dry mix.
Failure to flower
Usually caused by insufficient direct sunlight or over-fertilising with nitrogen-heavy feeds. Move the plant to full sun and switch to a low-nitrogen, high-phosphorus fertiliser (bloom booster) in late spring to trigger flower bud initiation.
Spider mites in hot, dry conditions
Fine webbing and stippled leaves are the telltale signs. Increase air circulation and mist the undersides of leaves periodically. Treat with insecticidal soap or neem oil, repeating every 5–7 days until resolved.
