Pencil-leaf Tylecodon problems — and how to fix them
Pencil-leaf Tylecodon (Tylecodon cacalioides) 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 poor drainage
The most common problem in cultivation. Use a very gritty mix and a pot with multiple drainage holes. Do not use a saucer that retains water. In humid climates, raise the pot to improve air flow around the base.
Leaf drop in summer
T. cacalioides naturally drops its leaves in summer dormancy. This is normal — do not increase watering in response. Resume normal watering when new leaf clusters appear at branch tips in autumn.
Mealybugs and scale
The dense leaf tufts and branch junctions provide ideal hiding spots for mealybugs. Inspect regularly, particularly at the base of leaf clusters. Treat with isopropyl alcohol or insecticidal soap; repeat over several weeks.
