How to propagate Lycoris longituba? Introduction to common methods

Lycoris longituba is native to eastern China, with wild populations distributed in the middle and lower reaches of the Yangtze River. It is highly cold-tolerant and prefers shady, moist conditions. However, it also grows well in sunny spots. Well-drained, fertile sandy loam is the best soil. It has strong stress resistance and is easy to cultivate.

Propagation: Division and seed sowing are commonly used. For division, dig up the plants when the leaves or flower stems have just withered, then separate the bulbs. Planting depth is 10 cm; the contractile roots can automatically adjust the depth of the bulbs. For seed propagation, sow immediately after collecting the seeds. With autumn sowing, by the following spring the young roots germinate and form small bulbs; seedlings need 5-6 years to form flowering bulbs.

Cultivation: When new leaves sprout in spring, keep the soil moist; after the leaves wither in May-June, water less. Apply phosphorus and potassium fertilizer once before the flowering period in July-August, which can promote thick and sturdy flower stems and large, brightly colored flowers. After flowering, Lycoris longituba does not produce leaves, but the soil should still be kept moist. Potted soil must be well-drained and not waterlogged, to prevent the bulbs from rotting. The bulbs overwinter in the open ground.

Pests and diseases: Common diseases include anthracnose and rot. Before planting, soak the bulbs in 0.3% copper sulfate solution for 30 minutes, rinse with water, and plant after drying. At the early stage of disease, spray with 50% benomyl at 2500 times dilution.

Application: Lycoris longituba has beautiful flowers with considerable color variation, resembling lilies, and has high ornamental value. It is suitable for group planting under trees or in lawns, and can also be used as a potted plant or cut flower.
