Cold water flowers like sunshine, but they are afraid of strong light. In summer, cold water flowers should be kept in shade to avoid strong direct light. But make sure that the maintenance place is bright. But if the light is too dark, the leaf color will fade. In the sparse shade environment, the leaves of cold water flowers are clear white and green, with short and compact internodes and bright and glossy leaves. In the full shade environment, the cold water flowers often grow in vain, with longer internodes, soft stalks, prone to lodging and loose plant shape.
Master the principle of wetting management. It is better to keep basin soil dry without cracking and moist without wetting. Spray water regularly to keep the leaves clean and shiny. In winter, spray less water on the leaves, or the leaves will appear black spots or even black rot. At the growth stage, two weeks or so, 80% or 37% nitrogen liquid fertilizer was applied once to make the plant strong. After autumn, apply more P and K fertilizer to strengthen the stem and prevent lodging.
The suitable temperature for the growth of green flowers is 18-22 ℃, and the winter temperature should not be lower than 7 ℃. Only in the appropriate temperature, the plant grows rapidly, can better reflect its value.
In order to enhance the ornamental effect of cold water flower, it is necessary to prune it regularly during its growth period to promote its branching and keep its full plant shape. If you want to cultivate into a small potted plant, you should pick the heart regularly and prune properly to make it dwarf. Pay attention not to prune too much, otherwise it will easily lead to more and smaller leaves of cold water flowers, which will affect the aesthetics.
When the cold water plant grows to about 40 cm, the stem will fall outward. It should be cut short in time to promote new branches at the lower end of the plant, so that the branches are dense and compact.
Change basin at least once a year in spring, fertilize once a week in growing period, and fertilize once with nutrient solution. If the cultivation time is too long and the growth is slow, it should be pruned and cuttage renewed in time. Otherwise, the viewing effect will be reduced.
Cold water flowers like strong scattering light, covering more than 70% of the sun in summer. No shading or a little shading in winter. When overwintering, the temperature should be above 13 ℃. If the temperature is below 10 ℃ for a long time, the flowers and branches will be damaged. But in a short period of time about 5 degrees Celsius, there will be no harm.
Cold water flowers like a humid environment, often keep spraying moist and high air humidity. In the dry season, you can often spray water on the surrounding environment or leaves.
