What are the precautions for growing Oriental lilies (Lilium 'Oriental Hybrids') in water?
Nutrients
When growing plants in water, since plants need various nutrient elements for growth, plain water alone is not enough to support what the plant needs. So during the growth of Oriental lilies, we need to add nutrients to them to provide the driving force for their growth.
Changing the water
Like other water-grown plants, Oriental lilies need the water quality to remain acceptable when grown in water. Water that is not changed for a long time will retain some substances, and these will cause the water quality to deteriorate and affect the growth of Oriental lilies. Keeping up with frequent water changes can help the Oriental lily plants grow better.
Light
Generally speaking, the more light they receive, the more luxuriantly Oriental lilies grow. However, the suitable growing temperature for Oriental lilies is around 16 to 25°C; too much light will expose the plants to excessively high temperatures and affect their growth. In summer, when the sunlight is strong, we can reduce the sun exposure on Oriental lilies to prevent the plants from being damaged.
The above is an introduction to the question of how to prune Oriental lilies after they bloom. Although Oriental lilies are beautiful, their fragrance is intense when they bloom, so it is recommended not to place them in the bedroom, to avoid problems such as insomnia and restless dreams.

Change the water frequently
First of all, if you want to grow Oriental lilies in water, you must change the water frequently. Usually, at temperatures above 20°C, it is best to change the water once every 2 to 3 days; if the temperature is in the range of 15 to 20°C, changing it once every 3 days to 1 week is enough; if the temperature is lower still, it is best to change it once a week.
Plenty of sunlight
Oriental lilies grown in water very much need plenty of sunlight. When cultivating them, take care to keep the temperature between 15°C and 25°C. If the temperature is too low, Oriental lilies will not be able to grow normally. Also, if the daily light duration increases, the lilies will bloom earlier; but if there is not enough light, the flowering time will be delayed.
Add nutrient solution
The medium for cultivating Oriental lilies now is water, which lacks certain nutrient elements, so we need to add some suitable nutrient solution to help the plants grow. Of course, different plants need different nutrients, so we need to prepare a nutrient solution suitable for the plants' growth to meet their needs.
Prune in time
Oriental lilies are used for arrangements, decoration and so on, and generally need to be pruned regularly; usually pruning once every two to three days is enough. Regular pruning not only makes the lilies more beautiful, but also helps the plants absorb water more easily, and can also extend the lilies' flowering period.
Growth requirements
Note that during water cultivation, the ambient climate is best warm, humid, cool and cold; the temperature must not be too high, and in summer it is best to keep them indoors.
How to prune Oriental lilies after they have bloomed
Withered flowers
After Oriental lilies finish blooming, the flowers will wither. However, the leaves of Oriental lilies can still carry out photosynthesis and send nutrients into the retained roots and stems, so after the Oriental lilies have finished blooming, you only need to cut off the spent Oriental lily flowers.
Withered leaves
When the leaves of Oriental lilies gradually wither and the plants stop growing, we need to prune them. When pruning Oriental lilies, cut off all the dead branches and leaves and keep the bulbs. The next year, replant the bulbs, and the Oriental lilies will sprout again.
When Oriental lilies are grown in soil, besides pruning there are many other things to pay attention to. So what problems should we pay attention to when growing Oriental lilies in water?
