Troubleshooting
Brush Cherry problems — and how to fix them
Brush Cherry (Syzygium australe) 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 failure, particularly in containers. Symptoms include yellowing leaves, soft stems, and rapid wilting. Always use free-draining substrate, water only when the topsoil begins to dry, and never allow pots to sit in standing water.
Psyllid leaf pitting
Pimple psyllids (Trioza eugeniae) cause raised, blister-like pits on new foliage, reducing ornamental value on hedges. At first sign, spray with horticultural oil and a systemic insecticide. Prune out the most affected shoots and feed to encourage healthy new growth.
Spider mites in dry conditions
Fine webbing and bronzed, stippled leaves indicate spider mite infestation, especially on indoor or bonsai specimens in dry air. Increase humidity, spray foliage undersides with water regularly, and apply a miticide or neem oil solution at the first sign.
