Propagation Methods and Care Tips for Oriental Lilies

Oriental lilies are one of the most common flowering plants grown at home, and women are especially fond of them. Growing this flower is not simple either. Below, let's look at how to propagate Oriental lilies and what to pay attention to when growing them.

How to grow Oriental lilies - propagation methods:

There are many propagation methods for Oriental lilies. The most important ones are introduced below.

1. Bulb propagation: The number of bulbs is relatively small, so it cannot become the main propagation method, but it can still be used.

2. Bulbil propagation: The purple-black bulbils, similar to small bulbs, can be used for propagation.

3. Seed propagation: Lily seeds are divided into fast-sprouting and slow-sprouting types. Slow-sprouting seeds must go through: storage - rooting - small bulb formation - flowering and other processes, while the fast-sprouting type has a relatively shortened process.

4. Cutting propagation: The stems and leaves of lilies near the ground can regrow in water or moist soil.

Growing methods

1. Soil: Oriental lilies prefer fertile, deep soil rich in humus, and most of all dislike hard clay; well-drained, slightly acidic soil is best, with a soil pH of 5.5-6.5.

2. Watering: Watering only needs to keep the potting soil moist. The potting soil should not be too wet, otherwise the bulbs rot easily.

3. Light: Potted lilies have different requirements for light intensity at different growth stages. During the bud stage, shading treatment is needed. If the leaf temperature is too high, appropriate shade should also be provided. At other growth stages, light should be increased, especially during flower development. Temperature: The growth and flowering temperature for Oriental lilies is 16-24°C. Below 5°C or above 30°C, growth almost stops. Only above 10°C do plants grow normally. Above 25°C, growth stalls again. If the nighttime temperature in winter is below 5°C for 5-7 consecutive days, flower bud differentiation and flower bud development will be seriously affected, delaying flowering or even causing blind flowers and split flowers.

4. Fertilizing: Lilies need relatively large amounts of nitrogen and potassium fertilizer, and should be applied once every 10-15 days during the growing period. However, phosphorus fertilizer supply should be limited, because too much phosphorus fertilizer causes yellowing leaves. (During the flowering period, phosphorus fertilizer can be added for 1-2 days.)

5. Pests and diseases:

(1) Gray mold: Use captan, thiophanate, or zineb at 500 times dilution for control.

(2) Damping-off: Before planting, soak in 500 times diluted furametsen or 50 times diluted 40% formaldehyde for 15

(3) Root rot: Remove diseased plants, then disinfect the soil with dexon.

(4) Insect pests: For aphids, mites, white grubs and cutworms, use omethoate, dicofol and poison bait for control.

6. Pruning: To make the bulbs plump, lilies can be cut off at the base after flowering to reduce nutrient consumption, because flowering has already consumed a lot of the bulb's nutrients. If you want to keep the bulbs for continued planting, you must continue fertilizing to replenish the bulbs' nutrients. After one month, the bulbs can be dug out, the fibrous roots cut off, and placed in the refrigerator for a period of cold storage to break dormancy before planting again, but flower quality will decline.

Care tips:

1. Flowering regulation: If you want Oriental lilies to bloom from November to early February of the following year, treat the bulbs first at 13°C for 2 weeks (14 days), then at 3°C for 4-5 weeks (28-36 days). In this way, they can bloom from November to December. If you want them to bloom from January to February, first treat at 13°C for 2 weeks, then at 8°C for 4-5 weeks (28-36 days). At this time, after planting, the nighttime temperature is relatively low, so heating should be added to maintain around 15°C.

2. Bud abortion treatment: During forcing cultivation of lilies, when flower buds grow to 1-2 cm, if light is insufficient, bud abortion easily occurs. Bud abortion often occurs from the end of October to mid-March of the following year. It can be prevented by supplemental lighting with artificial light. The method is to hang one 40-watt high-pressure sodium lamp, or an ordinary waterproof incandescent lamp, every 8-10 sq m. Supplemental lighting should begin before the flower buds reach 0.5-1 cm and continue until harvest. At 16°C, maintain lighting for about 6 weeks, from 8 p.m. each day to 4 a.m. the next morning. This is very effective in preventing bud abortion, advancing flowering and improving cut flower quality.

3. Excessive plant elongation: During the growing period, Oriental lilies should also have the flowerpot turned once a week. Otherwise, the plant tends to grow lopsided, affecting its appearance.
