Can Luoshenhua be planted in the north? Introduction to the planting method, time and nutritional value of Luoshenhua

How do you grow roses, you know? Do you want to know? Let's take a look together! In the process of planting, we should pay more attention to the common diseases and maintenance of Roselle flowers!

In the north, the planting time of Roselle flower is about 3~4 months, with full sunshine best, Roselle flower stops growing when the temperature is 10 degrees Celsius, will wither when 5 degrees Celsius, because the weather is still cold after the end of the year, too early seedling Roselle flower will freeze to death, so I choose to let the seeds germinate in early April.

First, soak the seeds of Roselle Flower in water for one day, pour out the water, put them into plastic bags (heat-resistant bags, opaque), and put them in the pockets on the body to germinate (the body temperature is higher, germination is faster)

Take it out about 3 to 4 days and plant the germinated seeds in a small pot. The other seeds are still in the pocket for germination.

Roselle seedlings planted in small pots about 20~30 cm high can be transplanted to nurseries, because Roselle is a shallow root plant, which is easily blown down by strong winds (such as typhoons), so it is necessary to fix the seedlings with sticks during transplantation for future care. After transplanting, apply fertilizer for the first time (organic fertilizer or chemical fertilizer) about 2 weeks later, and grow to 160~200 cm in about 3 months. Apply fertilizer again when flowering. Flowering occurs in September and October of each year, and harvesting occurs one month after flowering. Roselle flower resistance to pests and diseases is very good, with seeds or cuttings will live, do not need too much planting skills or care, quickly grow into a piece.

When Roselle flowers are planted, the capsule on the branches close to the root should be selected. After it is completely dried, the seeds should be removed (the capsule is divided into five chambers, and each chamber has 5~7 seeds) and stored at room temperature or refrigerated. The commercially available Roselle flowers are picked because the seeds are not mature enough, so even if they are dried, they basically will not germinate.

Roselle flowers have a high utilization value. Flowers, roots and seeds can be used as medicinal materials. Among them, the seeds are recorded in the pharmacopoeia as having the effects of strengthening, diuresis and diarrhea; the fruit sepals have the effects of clearing heat, quenching thirst, relieving cough and lowering blood pressure. Fresh fruit calyx also contains malic acid, which can be used as jam, fruit juice, jelly, tea bag, preserved fruit and cool drink. Sugar fermentation can make wine; immature fruit calyx can be used as raw material of vinegar or as vegetable, tender leaf raw food or cooked food; dry stem fiber can be used as textile and papermaking. Roselle flower is rich in anthocyanins, flavonoids, polyphenols, can beautify beauty, adjust blood lipids, maintain liver health role. Roselle flower has antipyretic, anti-hypertension, liver disease treatment, and pH balance effects in the body; scientists have further discovered that Roselle flower extracts are quite helpful in preventing cancer, congee hardening, helping digestion, anti-aging, and inhibiting free radical activities; sour and sweet Roselle flower tea is also the best summer drink in Taiwan.
