Hibiscus is usually planted in May. It is better to plant it directly on the open ground. The seed coat of the flower is very hard, so it is necessary to select the flower seeds with full seeds before sowing, and then soak the seeds in warm water for about 12 hours, and then plant the seeds into the pot soil when the flower seeds are about to sprout. After that, attention should be paid to watering. It is better to keep the soil in a slightly wet state all the time. It can also be properly covered with plastic film to keep warm and promote the germination of seeds. Under normal conditions, it can germinate in a week or two. When the leaves begin to grow, gradually remove the mulch, and remove the weak seedlings, leaving only healthy and full-bodied ones. Apply a light liquid fertilizer once a week or so to ensure sufficient nutrients and promote the growth of seedlings. When the seedlings grow four or five leaves, they can be transplanted.
The cutting of Hibiscus flower is relatively simple. In the growth period of the plant, select a healthy and strong mature branch with buds and cut it, with a length of about 10-15cm. Trim the lower part of the leaves, and only keep the top three or five leaves. Insert the branches into the moist sandy soil, about half of the cuttings, and then water reasonably to ensure the soil is wet. Pay attention to the appropriate shading treatment for the new plants, avoid direct sunlight, and the branches can take root and grow in about a month, then gradually reduce the shading and increase the light, and carry out normal maintenance..
Hibiscus flower should be propagated in the spring and autumn seasons by using the split plant method. The mother plant should be dug out from the soil, the extra soil on the root should be gently removed, the root should be washed clean, and the residual and rotten roots should be cut and pruned. Follow the trend of natural growth to divide the mother plant into several small bundles, and pay attention to each bundle with a part of healthy roots. Separate several small plants and plant them in the prepared soil, pay attention to appropriate watering, and carry out reasonable routine maintenance. The survival rate of Hibiscus flower which propagates by the method of dividing plants is generally high, and it can normally resume growth and bloom as scheduled in the year of dividing plants.
