A Detailed Introduction to the Latest Propagation Methods for Red Spider Lily

The red spider lily (Lycoris radiata) is a plant of the Amaryllidaceae family. It prefers shady and moist environments, fears direct strong light, and is best grown in loose, fertile sandy loam. It is widely cultivated around the world and is an excellent perennial herbaceous flower. It can be propagated by methods such as bulb division, sowing, scale-base cutting, and tissue culture, with bulb division being the main method. Let us take a look together below!

Propagation by Bulb Division

Propagation by bulb division is the simplest propagation method. During the dormant period or after flowering, dig up the plant, remove the offset bulbs attached near the mother bulb and plant them. They will bloom in about one to two years.

Scale Cutting Method

Cut the cleaned bulb base into eight sections in a star pattern, with a cutting depth of about 1/2 to 2/3 of the bulb length. After disinfection and drying in the shade, insert them into moist sand, perlite, or other substrates. After 3 months, adventitious buds can be seen forming at the junction of the scales and the basal plate, gradually producing small bulbils, which can become seedlings after separation and cultivation.

Tissue Culture Method

Using MS medium, take flower stalks and ovaries as explant materials. After culturing, callus tissue can be produced at the cut surface. After 1 month, adventitious roots can form, and after 3 to 4 months, adventitious buds can form. Using flower stalks and scales with stems as explant materials can also produce adventitious buds and daughter bulbs.

Propagation by Sowing

This is generally only used for hybrid breeding. Since the seeds have no dormancy, they should be sown immediately after collection. At 20°C, the radicle can be seen emerging after 15 days. When sown in a natural environment, only a few seedlings produce a single leaf in the first growth cycle, and the seedlings can be transplanted once during the seedling stage. Seedlings take about 4 to 5 years from sowing to flowering.
