Cultivation Methods and Precautions for Chinese Crinum Lily

I. Cultivation Methods

1. Soil: The Chinese Crinum Lily is not demanding about soil and is tolerant of saline-alkali conditions. It grows better in soil rich in humus, loose and fertile, with good drainage.

2. Watering: During the growing season, the Chinese Crinum Lily needs sufficient water. Keep the soil moist frequently, but do not let it become waterlogged. After autumn, reduce watering.

3. Sunlight: In the scorching heat of midsummer, the Chinese Crinum Lily should be properly shaded. From 7 a.m. to 12 p.m., it should receive full sun; from 12 p.m. to 3 p.m., a shade awning should be set up for shade.

4. Temperature: The Chinese Crinum Lily likes warmth and is not cold-tolerant. The suitable growing temperature is 15-20°C. In winter, it needs to overwinter indoors at no less than 5°C.

5. Fertilizing: The Chinese Crinum Lily likes fertilizer. Apply manure fertilizer 2-3 times per month, and add phosphorus fertilizer 2 more times before and after flowering, which helps produce more flowers and prolongs the flowering period.

II. Precautions

1. Cooling and humidifying in summer. The Chinese Crinum Lily fears scorching sun exposure in summer. Therefore, after summer arrives, move the plant to a shade awning or a north-facing balcony for care, and frequently sprinkle water on the ground to create a cool and humid micro-environment.

2. Fertilize frequently during the growing period. During the growing period, apply thin fertilizer frequently. In spring, apply thin fertilizer mainly of nitrogen; during the scape-extending and bud-setting period, apply liquid fertilizer mainly of phosphorus and potassium; in autumn, apply decomposed cake fertilizer. The interval between fertilizations is 2 weeks.

3. Water frequently during the growing period. In spring, water once every 1—2 days; in summer, water once every evening; after autumn arrives, reduce watering; in winter, strictly control watering (generally water once about every 2 weeks).

How to Water-Culture Chinese Crinum Lily

1. Use a transparent glass container; it needs to meet the nutrient requirements during the growing period and allow photosynthesis. When water-culturing, keep the water amount appropriate, no sandy soil is needed, and keep the roots white.

2. During the growing period, carry out water and fertilizer management. Water every day, not too little, and from May to September, add fertilizer once every 1-2 weeks, then stop after winter arrives.

3. Remove spoiled buds. During its vigorous growing period, spoiled buds and tiller buds often grow from around it, and these need to be removed.

4. To make the leaves green and beautiful, light and shading are needed. In midsummer, from morning to noon each day, it needs sunlight exposure, and in the afternoon it should be shaded.

What to Do If the Chinese Crinum Lily's Roots Rot

If the roots of the Chinese Crinum Lily have rotted, it is not easy to cure. Pull the plant out of the pot, quickly cut off the rotted root parts, use potassium permanganate for disinfection, and replant it in the pot. If only a small amount has rotted, the above method can be used. After about three days, it can be replanted and given normal care. During its growing period, be sure to keep water and fertilizer sufficient, and do not water too frequently or fertilize too much.

It turns out the Chinese Crinum Lily can be grown not only in soil but also in water. Water culture means placing it in a glass bottle, so that even the root system can be seen. With the effect of the glass container, it gives people another unique feeling, and water culture allows you to constantly monitor its root rot situation. If it occurs, it can be discovered and treated in time.
