1. Soil: The potting culture soil for lilies should be prepared by mixing leaf humus soil, sand soil and garden soil in a ratio of 1:1:1. Apply enough fully decomposed compost and a small amount of bone meal and bone meal to the bottom of the pot. For base fertilizer.
2. Sunlight: Lilies like light. If there is a lack of sunlight, long-term shading will affect normal flowering. Additionally, turn the pot once a week during the growing season. Otherwise, the plant will easily become too long, affecting its appearance.
3. Temperature: The temperature for lily growth and flowering is 16 to 24°C. The growth almost stops when it is below 5°C or above 30°C. Plants grow normally only when it is above 10°C, and the growth stops when it exceeds 25°C. , if the night temperature in winter is lower than 5℃ for 5 to 7 days, flower bud differentiation and flower bud development will be seriously affected, flowering will be delayed or even blind flowers and flower cracks will occur.
4. Watering: Watering only needs to keep the pot soil moist, but it must be watered appropriately during the peak growing season and during dry weather, and water should often be sprinkled around the flower pot to increase the air humidity. The pot soil should not be too wet, otherwise the bulbs will rot easily.
5. Fertilization: Lily does not have very high requirements for fertilizers. Fertilizers are usually applied at the beginning of spring growth and early flowering. Some foreign cultivators believe that lilies require a lot of nitrogen and potassium fertilizers and should be applied every 10 to 15 days during the growth period, while the supply of phosphate fertilizers should be limited because too much phosphate fertilizer will cause the leaves to wither and turn yellow. Phosphate fertilizer can be applied for 1 to 2 days during the flowering period.
6. Pests: Common diseases of lilies include lily mosaic disease, bulb rot, spot disease, leaf blight, etc. When the spot disease appears, the diseased leaves can be removed and sprayed once with a 500-fold dilution of 65% zinc wettable powder to prevent the spread.
7. Pruning: In order to enrich the bulbs, the remaining flowers should be cut off in time after blooming to reduce nutrient consumption and affect the blooming of other flowers.
8. Propagation of lilies by bulbs: If you need to propagate one or several lilies, you can use the method of propagation of lilies by bulbs. There are usually some small bulbs growing around the stem disk of older bulbs. When harvesting lilies from September to October, these small bulbs can be separated and stored in sand indoors to overwinter. Plant in pots the following spring. From September to October of the third year of cultivation, they can grow into large bulbs and be cultivated into large plants. The propagation volume of divided bulbs is small and they are only suitable for home potted propagation.
9. Sowing and propagation of lilies: Lily can choose the seeding and propagation method. The main method is to collect seeds in autumn and store them until sowing in the following spring. Germination takes place about 20 to 30 days after sowing. Appropriate shade should be provided during the seedling stage. In autumn, small bulbs have formed in the underground part, which can be dug out and planted separately. Depending on the type of sown seedlings, some will bloom in 3 years, while others will need to be cultivated for many years to bloom, so it is not suitable for families to use.
10. Lily scale cutting propagation: The lily scale cutting propagation method can be used for medium-volume propagation. Dig out the bulbs in autumn, and break off the full and thick scales on the old scales one by one. The base of each scale should have a small part of the stem plate, dry it in the shade, and then cut it into a flower pot filled with river sand (or vermiculite). Or put it in a shallow wooden box, insert 2/3 of the scales into the substrate, and maintain a certain humidity of the substrate. Under conditions of about 20 degrees, roots will take root in the wound of the scales in about one and a half months. The humidity in winter should be kept around 18 degrees, and the river sand should not be too wet. After being cultivated until the following spring, small bulbs will grow from the scales. Divide them up, plant them in pots, and manage them carefully. They will bloom after about 3 years of cultivation.
11. Propagation of lilies by bulbils: The propagation method of lilies by bulbils is only applicable to a few species. This method is often used for lilies such as Dandelion and Huangtiepao. The method is: take out the small bulbs (also called "bulbules") formed in the axils of the stems and leaves on the ground and cultivate them in the summer when the bulbils have fully grown but have not yet fallen off. It usually takes 2 to 4 years from growing into a large bulb to blooming. In order to promote the production of multiple small bulbils for reproduction, after the plant blooms, the above-ground stems can be overturned and buried shallowly in the soil. Divide the above-ground stems into small sections with 3 to 4 leaves each, and bury the stem nodes shallowly in wet sand. All can grow small bulbils.
12. Lily tissue culture propagation: The lily tissue culture propagation method is to use different parts of the lily, such as filaments, styles, ovaries, and axillary bud tissue at the base of the scales to culture them into test tube seedlings, and then transplant them into test tube seedlings. Seedbed care is grown for the production of bulbs. There are many ways to propagate lilies, but for family breeding, which does not require a large quantity, the most suitable method is the bulb propagation method, which is convenient and simple, and can also maintain the excellence of the original variety.
