Troubleshooting
Ernst's Spurflower problems — and how to fix them
Ernst's Spurflower (Plectranthus ernstii) 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 killer — stems turn soft and mushy at the base; remove affected tissue, let roots dry, and repot in fresh dry gritty mix; take cuttings to rescue a severely damaged plant.
Nematodes (root eelworms)
Root-knot nematodes can colonise the tuberous roots; affected plants show stunted growth and yellowing; discard the soil, re-root healthy stem cuttings in fresh sterile mix.
Slugs and snails
Outdoor or patio plants are attractive to slugs, which rasp irregular holes in the fleshy leaves; use copper tape around pot rims or organic slug pellets approved for use around pets.
