Waterlily Tulip problems — and how to fix them
Waterlily Tulip (Tulipa kaufmanniana) 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.
Bulb decline in poorly drained soils
T. kaufmanniana is more reliably perennial than hybrid tulips but will decline rapidly if soils stay wet in summer. In heavy soils, lift bulbs after foliage dies down, dry thoroughly, and store in a cool airy place until autumn replanting.
Tulip fire (Botrytis tulipae)
Grey mould sporulating on twisted, scorched-looking shoots in wet springs — the fungus overwinters on infected bulbs. Plant only clean, firm bulbs; remove and destroy infected material; avoid replanting tulips in the same spot for 3 years.
Rodent and squirrel predation
Bulbs are frequently dug up and eaten by squirrels, mice, and voles, particularly in autumn after planting. Plant through wire mesh baskets or lay chicken wire flat just below soil level over the planting area to deter digging. Plant deeply (15 cm minimum) to reduce accessibility.
