Troubleshooting
Isalo Adenia problems — and how to fix them
Isalo Adenia (Adenia isaloensis) 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.
Caudex rot
The most common and lethal issue, caused by overwatering or poor drainage — especially during dormancy. Ensure the potting mix is 50%+ inorganic material and water only when the caudex looks slightly less firm. If soft mushy tissue is found, cut it away with a sterile blade, dust with sulphur, and dry the plant for two weeks before repotting.
Leaf drop outside dormancy
Premature leaf shed in summer usually signals cold stress, root damage, or severe underwatering. Check that temperatures stay above 18°C and that roots are healthy before increasing water.
Spider mites
Dry indoor conditions encourage spider mite colonisation on new leaf growth. Look for fine webbing and stippled leaves. Treat with neem oil or insecticidal soap spray; increase air circulation.
