Essential Guide to Digging Up and Storing Narcissus Bulbs for a Vibrant Garden

Digging up narcissus bulbs is a crucial step in propagating these beautiful flowers and preserving their vibrant appearance for seasons to come.

Why Dig Up Narcissus Bulbs?

Narcissus plants can thrive in the same spot for up to five years, but each season they produce new bulbs that gradually crowd each other. This overcrowding causes the plants to weaken, leading to diminished or absent flowering. When you notice these signs, it’s time to dig up your narcissus bulbs to rejuvenate your garden.

When to Dig Up Narcissus Bulbs

Although narcissus flowers fade by May, avoid digging them up immediately after blooming. The ideal time is mid-July to early August, when the leaves have yellowed and dried. The condition of the foliage is the best indicator that the bulbs are ready to be lifted.

How to Properly Dig Up Narcissus Bulbs

Choose a dry, sunny day to work, ensuring no rain is forecasted for several days so the bulbs can dry properly after digging. Equip yourself with a spade and pruning shears, disinfecting the blades with alcohol to prevent disease transmission.

Insert the spade into the soil about 4 to 5 inches away from the base to avoid damaging the bulbs. Gently lift the clump out of the ground.

Shake off excess soil and trim the foliage, leaving only a 1 to 2 cm stub. The trimmed leaves can be composted.

Preparing Narcissus Bulbs for Storage

Lay the bulbs out in a sunny spot to air dry for 1–2 days, covering them overnight or moving them under a shelter to protect from dew and moisture.

Next, bring the bulbs indoors to dry for 20–25 days at 68–72°F (20–22°C). After drying, remove any remaining soil, old scales, and roots carefully with pruning shears to avoid damaging the bulb base, as these can harbor pests and diseases.

Discard any bulbs showing dark or yellow spots, mold, or swelling, as these indicate disease.

Sort the bulbs by size. Smaller bulbs under 2 cm diameter and 6–7 cm circumference may not bloom the following season but can be planted to mature. Larger bulbs are suitable for central placement in flowerbeds for impressive spring blooms.

Storing Narcissus Bulbs

Store sorted bulbs in a dark, well-ventilated area with temperatures between 50–59°F (10–15°C). Avoid treating the bulbs with chemicals until just before planting.

Use wooden crates, plastic mesh containers, buckets, or cardboard boxes with ventilation holes lined with paper. Arrange bulbs in no more than 1–2 layers. Avoid plastic bags or wrap, which trap moisture and cause rot.

To retain moisture, consider these storage techniques:

• Wrap each bulb in breathable materials like tissue paper or kraft paper, or place several bulbs in natural fabric bags such as linen or cotton.
• Cover bulbs partially or fully with vermiculite, a mineral soil conditioner.
• Use sawdust, such as pet litter-grade wood shavings, to cover bulbs halfway or completely.

Check the bulbs weekly for signs of mold or rot and remove any affected bulbs promptly to prevent spread.

Bulbs do not require long storage and should be replanted within 1–2 months of digging, typically from late August to late September, depending on your climate zone.

Pre-Planting Treatment

Before planting, soak bulbs in a fungicide and insecticide solution to protect against pests and diseases. Popular options include combining fungicides like "Fitosporin" or "Trichodermin" with insecticides such as "Actara" or "Fitoverm." Prepare each solution separately according to instructions, then combine and soak bulbs for 30 minutes. Afterward, air dry for several hours before planting.

If you miss the optimal planting window, you can store bulbs through winter by treating them with a fungicide soak and then refrigerating in breathable bags or ventilated boxes at 37–45°F (3–7°C). Keep bulbs away from fruits and vegetables to avoid premature decay. Store them this way until spring, then repeat treatment before planting.
