If you want to keep roses in water, you should first prepare a suitable vase, and disinfect it before use to avoid bacteria inside. After disinfection, rinse with water and put some clean water in it.
Before water cultivation, it is mainly to prune the dried leaves, yellow leaves and the leaves at the lower end of the rose branches, because the leaves cannot be immersed in the water, which is easy to rot and pollute the water quality. The bottom of the flower branch should also be trimmed into a 45 ° diagonal shape, so as to increase the water absorption capacity.
After the above work is ready, insert the rose into the vase. If there is little water, add some appropriately. The water level is the best at the stem. If possible, you can add some nutrient solution, diluted beer or a small amount of white sugar
During the period of water cultivation, it is not allowed to be directly exposed to the sun. The cultivation environment should be well ventilated to avoid maintenance in a hot and stuffy place. And regular water change, it is best to change the dirty water as soon as possible, if not for a long time, the water quality will be poor, which will lead to the withering of roses.
