What is the growing environment of lilies like?

Growth habits: Lily is cold-resistant, but the most suitable growth temperature is between 15-25 degrees. It will not grow well if the temperature is below 10 degrees or above 30 degrees. Lily generally prefers slightly acidic soil with a pH value of 5.5-6.5 and soil rich in humus with a bulk density below 1 gram/cubic centimeter. Avoid flooding and prefer semi-shaded environment, but excessive shade will cause the flower stems to grow too long and the flower buds to fall off. Lily is a world-famous bulb flower. It is strong and likes cool, humid climate and semi-shaded environment. It avoids direct sunlight, is not cold-resistant, and avoids dry calcareous soil. It grows best in slightly acidic, deep, thick sandy loam with rich humus and good drainage. It has weak disease resistance and requires a well-ventilated cultivation environment.

How often should lilies be watered?

Water twice a day, once until the plant is wet, no need to water thoroughly. Change the water in the vase every 3 to 5 days. Each time you change the water, cut off about 1 cm from the incision of the lily stem, which can make the lily absorb water faster and easier, so that the lily can bloom for a longer time. There are many varieties of potted lilies with various colors. Use it to place it in the hotel lobby, airport terminal, and commercial building windows, which is fresh and pleasing to the eye, simple and natural. Several pots decorate the room or small garden, which is gorgeous and full of texture. Lily bulbs are soaked in 2 mmol/L silver thiosulfate solution for 24 hours before planting or potting. Under the condition of 20℃, the flowers that grow later will have a longer life. Flowers are sensitive to ethylene, and the plants should be sprayed with silver thiosulfate solution to prevent flowers and leaves from falling during low-temperature storage and transportation. Potted lilies can be stored for 14 to 28 days at 0 to 3℃.

Why are the leaves of lilies turning yellow?

Pay attention to the following six aspects, which are the main causes of yellowing:

1. Yellowing: caused by over-watering, characterized by no obvious changes in old leaves and yellowing of young leaves. Water should be controlled immediately.

2. Yellowing due to drought: caused by lack of water and drought, its characteristic is that the old leaves turn yellow first from the bottom to the top. If the water shortage lasts for a long time, the whole plant will turn yellow or even die. Watering should be done in time.

3. Yellowing due to fertilizer: caused by excessive fertilization or too high a concentration. The characteristics are that the young leaves are thick, shiny, and uneven. Fertilizer, inter-cultivation, and watering should be controlled.

4. Yellowing due to lack of fertilizer: caused by insufficient fertilizer, low fertilizer concentration, and long intervals between fertilizer applications. Its characteristic is that young leaves and tender stems turn yellow first. If fertilizer is not applied in time after seeing this phenomenon, it will cause yellowing leaves of the whole plant or even death. For flowers that lack fertilizer, avoid applying a large amount of concentrated fertilizer at one time to avoid burning the roots.

5. Yellow leaves due to iron deficiency: Woody flowers in greenhouses often have yellow leaves due to large changes in soil fertility conditions. The characteristics are that young leaves are obvious, old leaves are lighter, the leaf flesh is yellow, the veins are green, and a typical network is formed. It can be solved by applying ferrous sulfate aqueous solution. The method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water to make a double solution and water it.

6. Pests and diseases: Pests and diseases can also cause yellowing of leaves. At the same time, water and fertilizer management and pest and disease control must also be done well.
