Troubleshooting
Common Garden Tulip problems — and how to fix them
Common Garden Tulip (Tulipa gesneriana) 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.
Tulip fire (Botrytis tulipae)
The most serious tulip disease — distorted, scorched-looking shoots with grey fungal spores in wet springs. Lift and destroy affected bulbs; do not replant tulips in the same site for at least 3 years. Choose disease-resistant varieties and space bulbs to allow airflow.
Basal rot (Fusarium oxysporum)
Pink or brown rotting at the base of bulbs, often only noticed at planting time or when plants fail to emerge. Caused by waterlogged or warm summer soil. Lift bulbs in summer, inspect, discard any soft or discoloured bulbs, and store in a cool dry place.
Failure to rebloom (blind bulbs)
Bulbs in mild climates or poor-draining soils often produce only foliage in subsequent years. Modern hybrid tulips often need a cold winter to initiate flowering; in USDA zone 8+ pre-chill bulbs for 12–14 weeks at 5–7°C before planting. Allow foliage to die down naturally to rebuild bulb reserves.
