Method for Storing Narcissus Bulbs
As one of China's top ten famous flowers, narcissus is deeply loved by horticulture enthusiasts for its elegant fragrance and unique shape. Mastering scientific bulb storage and selection methods is a key step to ensure the quality of reblooming flowers next year. This article will analyze the five core points of bulb treatment from a professional perspective to help you cultivate superior narcissus plants.
Complete Guide to Storing Narcissus Bulbs
Dry and Cold Storage Method
After the flowers of hydroponic or soil-grown plants fade, it is necessary to immediately cut off the remaining flowers and withered leaves, leaving a 5cm stem. Use a brush to remove the soil attached to the surface of the bulb, especially paying attention to the cleaning of the spaces between the scales. It is recommended to use a 50% carbendazim solution (800 times) to soak for 20 minutes for disinfection, then hang in a cool and well-ventilated place to dry for 3-5 days until the epidermis is completely dry. After treatment, wrap the bulbs with breathable newspaper and store them in a refrigerator at 4-6°C, maintaining an environmental humidity of ≤60%. This method can effectively store bulbs for 8-10 months and is especially suitable for cold winter regions.
Deep Burial in Soil Storage Method
Suitable for soil-grown plants in gardens, choose sandy loam soil with high terrain and good drainage. Dig a planting hole 25cm deep, with a 3cm thick layer of decomposed pine needles at the bottom as a water-resistant layer. Arrange the bulbs in a triangular pattern, spaced 8-10cm apart, and cover with a mixture of fine sand and peat soil. Check the soil moisture every month, controlling the water content between 18-22%. When new leaves sprout to 5cm, apply a phosphorus-potassium compound fertilizer (N-P-K=5-10-10) to promote bulb nutrient accumulation.
Rules for Selecting High-Quality Narcissus Bulbs
Four Elements of Visual Identification
High-quality bulbs should have: ① A circumference of ≥22cm, with a flat conical shape; ② Outer scales that are evenly brown with a waxy luster; ③ A complete base plate with 3-5 circular root marks visible; ④ 2-4 lateral buds symmetrically distributed next to the main bud. Special attention should be paid to removing bulbs with mold spots or mechanical damage.
Three Standards of Touch Sensation
Hold the bulb with both hands to feel the weight; the weight of a qualified bulb should be within the range of 80-120g. Press the middle of the bulb with the thumb; a high-quality bulb should have a moderate resilience. Rub the outer scales to produce a crisp sound; if there is a soft feeling or the epidermis easily falls off, the bulb is dead.
By using scientific storage methods and rigorous selection criteria, the success rate of narcissus planting can be significantly improved. It is recommended to conduct bulb vitality tests every autumn and mix high-quality bulbs with humus soil at a ratio of 1:3 for storage. Mastering these core technologies will ensure that your narcissus blooms beautifully year after year.
