Daffodils are the backbone of the spring cutting garden — reliable, deer-proof, and available in forms ranging from the classic large yellow trumpet to white-and-orange split-cups. Plant bulbs in autumn at three times their depth. In Zone 6b they naturalise freely and multiply over years without lifting.
As cut flowers, daffodils exude a sap that shortens the vase life of other flowers in the same water. Condition them alone for 12 hours first; after conditioning the sap stops and they can be arranged with anything. Cut when the bud is just beginning to show colour but has not yet opened.
Botrytis (grey mould)
Grey fuzzy mould on petals and stems, worst in cool wet conditions.
Remove affected parts immediately. Improve air circulation. Avoid overhead watering. Apply copper fungicide if severe.
Narcissus Basal Rot
Brown rot starting at the base of the bulb, spreading upward; soft, decaying tissue and stunted or failed growth in spring. Fungal growth may appear pink or white.
Discard infected bulbs. Plant only firm, healthy bulbs in well-draining soil. Avoid hot, wet conditions during summer dormancy and rotate planting sites.
Narcissus Yellow Stripe Virus
Yellow or pale streaks running lengthwise along leaves; distorted foliage and reduced flower size or vigor over successive years.
No cure. Remove and destroy infected plants. Control aphids, which spread the virus, and buy certified virus-free bulbs.
