Groby's Specklinia problems — and how to fix them
Groby's Specklinia (Specklinia grobyi) 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.
Crown rot in warm, humid conditions
Unlike cool-growing Stelis, Specklinia grobyi grows at intermediate temperatures where warm moist air accelerates bacterial and fungal rot. Keep water off the central growing points, improve airflow, and treat any soft, discoloured tissue promptly with a fungicide.
Mealybugs and aphids
Both pests attack new racemes and leaf axils. Mealybugs appear as white cottony clusters; aphids cluster on flower spikes. Treat with insecticidal soap spray or dilute neem oil. Inspect weekly and repeat treatment to break the pest cycle.
Failure to re-bloom
Specklinia grobyi can re-bloom from old racemes if left intact. Cutting spent spikes prematurely removes this potential. Leave dried racemes attached until they are completely desiccated. Ensure adequate light and a brief cooler rest in autumn to stimulate new flower production.
