Daffodil bulbs are perennial plants that undergo a natural dormancy period during summer. After blooming in spring, the foliage photosynthesizes and stores energy in the bulb for the next growing season. Once the leaves yellow and wither, the bulb enters dormancy, signaling it's time to dig them up (if necessary) for summer storage. This mimics their native habitat, where dry summers prevent rot.
Timing is critical for daffodil bulb storage. Wait until the foliage turns yellow and dies back naturally, typically 6–8 weeks after flowering. Premature digging disrupts energy storage, weakening the bulb. In most U.S. regions, this occurs in late spring to early summer. Avoid leaving bulbs in soggy soil, as excess moisture can cause rot during dormancy.
After digging, gently brush off excess soil but avoid washing bulbs, as moisture encourages fungal growth. Inspect each bulb for damage or disease—discard soft or moldy ones. Allow bulbs to cure in a dry, shaded, well-ventilated area (e.g., a mesh bag or newspaper-lined tray) for 1–2 weeks. This step ensures outer scales dry properly, reducing storage risks.
Daffodil bulbs thrive in cool, dry, and dark environments during summer dormancy. Optimal conditions include:
Never store bulbs in sealed plastic bags, as trapped moisture causes rot. A garage, basement, or closet often works well.
Check bulbs monthly for signs of shriveling, mold, or pests (e.g., bulb mites). If bulbs dry out, lightly mist the storage medium (e.g., peat moss or vermiculite) to rehydrate. Discard any deteriorating bulbs to protect healthy ones. In hotter U.S. regions (e.g., USDA Zones 8–10), refrigerate bulbs after drying, but keep them away from ethylene-producing fruits (e.g., apples).
Replant bulbs in early fall, about 2–4 weeks before the first frost. Choose a sunny, well-drained site and plant at a depth three times the bulb’s height (usually 6–8 inches). Water lightly after planting to encourage root growth. Proper summer storage ensures robust blooms the following spring.
