Roselle usually blooms after about 6 months of planting . After it grows, it is almost stalkless, with only 8-12 small bracts, which are red in color and have stiff hairs on the surface. The calyx is lavender and cup-shaped, and also has coarse hairs. It should be noted during the planting process that it is a short-day plant. During the period of flower bud differentiation, it is best not to exceed 5 hours of light, otherwise it will delay the flowering period. Roselle flowering processRoselle is planted in April or May. When the temperature starts to rise, the seeds will germinate quickly. Before burying them in the soil, they must be germinated by soaking them in clean water for 12 hours. Let it fully absorb water, put 4-5 seeds in the hole, and then cover the soil in time. Roselle likes to grow in a humid environment. When the seedlings grow to 15 cm high, pull out the weak and diseased seedlings, leaving only one strong seedling. When it grows to about 90 cm, it needs to be topped so that the roselle can bloom better. Roselle flowering timeThe flowering time of Roselle is around October to November every year. It is widely used. The calyx contains malic acid, which can be made into jam, juice and refreshing drinks. It can also be used to make wine after adding sugar. The young leaves of the unripe calyx can be eaten raw or cooked. |
