Troubleshooting
Swedish Ivy problems — and how to fix them
Swedish Ivy (Plectranthus verticillatus) 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 / wilting
Caused by overwatering or soggy compost; the plant wilts and stems blacken. Often easier to take healthy stem-tip cuttings and start afresh than to save a badly rotted parent.
Spider mites
Show as pale, stippled leaves with fine webbing, worse in hot, dry air. Rinse the foliage and treat with insecticidal soap, repeating after about a week.
Mealybugs
Appear as cottony white masses in leaf joints. Dab with cotton wool dipped in insecticidal soap or diluted alcohol and treat the whole plant.
Leggy or dull growth
A sign of too little light. Move to a brighter, indirectly lit spot and pinch back stem tips to encourage bushier, fuller growth.
