How to propagate Chinese hibiscus? A detailed guide to common propagation methods
1. Cuttings:
Usually carried out from May to October, or in a greenhouse in winter, but the survival rate is higher during the plum rain season. The best cuttings are one-year-old semi-lignified ones, 10 cm long; remove the lower leaves, keep the top leaves, make the cut flat, insert into a sand bed, maintain high air humidity, and keep the room temperature at 18-21°C; roots form 20-25 days after insertion. Treating the base of the cuttings with 0.3-0.4% indolebutyric acid for 1-2 seconds can shorten the rooting period. Transplant into pots when the roots are 3-4 cm long.
2. Grafting:
Usually carried out in spring and autumn, mostly used for Chinese hibiscus varieties that are difficult to root from cuttings or root slowly, especially double-flowered varieties with a low cutting survival rate. Either branch grafting or bud grafting can be used; use single-flowered Chinese hibiscus as the rootstock, and the grafted seedlings will grow branches and bloom in the same year.
That is all for today's content. I believe everyone now has a detailed understanding of the cultivation and propagation methods of Chinese hibiscus! For more information, please follow Four Seasons Plants Network!
Cultivation methods for Chinese hibiscus
1. Site selection and soil preparation:
Chinese hibiscus is very suitable for growing in warm, humid places, so when choosing a plot, be sure to choose fertile, well-drained sandy soil that is also slightly alkaline, which is more conducive to the growth of Chinese hibiscus.
2. Temperature control:
Chinese hibiscus is not tolerant of frost, so in winter the plant must be moved indoors, and the temperature must not be lower than 5°C to avoid frost damage. In addition, when the weather is hot, the temperature must also be controlled well; try not to let the temperature exceed 15°C, otherwise it will go dormant and stop growing.
3. Water and fertilizer management:
When cultivating Chinese hibiscus, be sure to pay attention to changes in the dryness and moisture of the potting soil. Proper watering can not only improve its growth quality but also prevent frost damage. In addition, early May is the growing season for Chinese hibiscus, so fertilizer and water management should be strengthened, applying a dilute liquid fertilizer once every 7 to 10 days.
4. Pruning techniques:
Chinese hibiscus needs pruning during cultivation, which can not only enhance the ornamental value of its shape but also avoid the occurrence of various pests and diseases. When pruning, except for leaving 2 to 3 buds at the base of each branch, cut off all the upper parts; after pruning, appropriately restrict water and fertilizer.
The above introduced the cultivation methods for Chinese hibiscus. Now let us introduce the propagation methods for Chinese hibiscus.
Cultivation methods for Chinese hibiscus
This article mainly discusses the cultivation methods for potted Chinese hibiscus. Chinese hibiscus is a very easy-to-grow flower and has the characteristic of blooming on new shoots, so it needs frequent pruning while keeping up with water and fertilizer; only then can it bloom continuously during the flowering period.Chinese hibiscus prefers a warm, humid, sunny environment and is not tolerant of drought or frost. North of the Yangtze River, it must be grown in pots, and in winter it must be moved indoors to overwinter (if there is heating indoors and the temperature reaches above 15°C, it will continue to bloom).
Chinese hibiscus likes light, so the growing location is best in a sunny place, such as a south-facing balcony. During the growing season of Chinese hibiscus, water and fertilizer management should be strengthened. Chinese hibiscus likes water very much, and many flower lovers have killed it from lack of water because they overlooked this point (do not water desperately just because it likes water; water according to the dryness and moisture of the soil). Fertilization should mainly be light fertilizer applied frequently, with a dilute liquid fertilizer applied once every 7-10 days. Be careful to reduce fertilization later to avoid producing autumn shoots. Autumn shoots are tender and have weak cold resistance, so they will suffer frost damage in cold weather.
Because Chinese hibiscus blooms on new shoots, pruning is especially important. Every year in early spring, before and after moving the plant out, prune and shape it: except for leaving 2-3 buds at the base of each branch, cut off all the upper parts. After pruning, because the aboveground part consumes less, appropriately restrict water and fertilizer.
Regarding the issue of Chinese hibiscus overwintering, let me nag a bit more here. Chinese hibiscus is not cold tolerant, and in the north it is generally grown in pots. When the temperature drops to 14°C at the lowest, it is recommended to move it indoors (except for enclosed balconies where the temperature can be controlled), so that it can continue to bloom.
