Hyacinths are popular spring-flowering bulbs known for their dense, fragrant blooms. While many gardeners leave these perennial bulbs in the ground year-round, lifting them after flowering is sometimes necessary for specific reasons. This process is typically done to thin overcrowded areas, protect bulbs from overly wet winter soil conditions, or prepare them for relocation. Successfully storing hyacinth bulbs over their dormant period ensures they produce colorful, scented flowers again next spring.
The Optimal Timing for Lifting Bulbs
The timing for removing hyacinth bulbs is determined by the plant’s natural life cycle, not the calendar. Lifting must occur only after the foliage has fully matured and died back naturally, which usually takes several weeks after the flowers fade. This period, typically in late spring or early summer, allows the leaves to complete photosynthesis.
During this time, the plant transfers energy and starches from the leaves back into the bulb for next season’s growth. The visual cue for lifting is when the foliage turns completely yellow and begins to shrivel, but has not yet fully disintegrated. Prematurely cutting the leaves off deprives the bulb of necessary energy, resulting in a weak or absent bloom the following year. Lifting bulbs when the soil is relatively dry is also beneficial, as excess moisture increases the risk of disease and rot during storage.
The Step-by-Step Process of Lifting and Cleaning
Once the foliage has collapsed and turned brown, the physical process of removing the bulbs can begin. Use a garden fork rather than a spade to reduce the likelihood of accidentally damaging the bulbs. Insert the tool several inches away from the plant’s base, then gently leverage it to loosen the earth and lift the bulb clump.
After lifting, shake off large clumps of loose soil. Trim away any remaining dead foliage or shriveled roots using clean shears. Inspect each bulb carefully for signs of damage, soft spots, or fungal growth, immediately discarding any that appear diseased or unhealthy. This cleaning step ensures a firm, intact bulb is ready for preparation.
Preparing Bulbs for Storage
Following cleaning, bulbs must undergo a short period of drying, known as “curing,” which hardens the outer layer for long-term dormancy. Spread the bulbs in a single layer on a wire rack or newspaper in a warm, shaded, and well-ventilated location. A garage or shed is suitable, with temperatures ideally maintained between 70–80°F (21–27°C) for two to three weeks.
After curing, the bulbs should feel dry and papery, indicating readiness for summer storage. Proper storage requires a cool, dry, and dark environment, typically ranging from 50–60°F (10–15°C). Use breathable containers, such as mesh bags, paper sacks, or shallow boxes with ventilation holes. Avoid plastic bags or sealed containers, as they trap moisture and promote mold and rot. Check the stored bulbs periodically throughout the summer for signs of moisture, shriveling, or disease, ensuring they remain viable for replanting in the autumn.
