Troubleshooting
Queen Pineapple problems — and how to fix them
Queen Pineapple (Ananas comosus 'Queen') 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 from excess water
Water pooling in the rosette or in heavy soil rots the crown; water sparingly, keep the cup dry in cool spells and use a free-draining mix.
Cold injury
Though slightly hardier than commercial pineapples, it is still damaged below about 8-10°C and killed by frost; overwinter indoors in temperate areas.
Spiny-leaf handling injury
Queen's leaf margins are sharply toothed and can scratch people and pets; site it out of busy traffic and handle with care.
Mealybugs and scale
These pests shelter deep in the leaf axils and rosette; inspect often and treat with horticultural soap or oil, avoiding copper-based pesticides.
