Horned Tulip problems — and how to fix them
Horned Tulip (Tulipa acuminata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Tulip fire (Botrytis tulipae)
Grey-brown scorched spots on leaves and petals, often with grey mould. Remove and destroy affected plants; do not replant tulips in the same spot for at least two years.
Basal rot (Fusarium oxysporum)
Bulbs develop a brown, disintegrating base, often noticed at planting or lifting. Discard affected bulbs; plant in fresh well-drained soil and avoid waterlogged conditions.
