How does the four o'clock flower (Mirabilis jalapa) reproduce? It can self-sow or be sown by hand.
We know that among the effects and uses of the four o'clock flower, its roots and seeds are very useful; the roots have the effect of clearing heat and detoxifying. The powder in the seeds can remove acne and pimples. In fact, besides these uses, they have another purpose, and that is reproduction. How does the four o'clock flower reproduce? Below we tell you the propagation methods of the four o'clock flower.
How the four o'clock flower reproduces
The four o'clock flower generally uses three propagation methods, namely seed sowing, tuberous roots and cuttings. Its propagation is much easier than that of other plants, especially propagation by sowing. It can be sown by hand, and it can also self-sow and multiply, with a reproductive capacity as strong as that of the dandelion.
Propagation methods of the four o'clock flower
1. Tuberous root propagation
1. Timing
Before the onset of winter, cut off the above-ground part of the four o'clock flower, then dig out the perennial root of the underground part, bury it in a flower pot with moist soil, and place it indoors to overwinter. Then, after the temperature rises in the spring of the 2nd year, dig out the perennial root and replant it.
2. Method
In spring, plant the lower one third of the tuberous root into the potting soil, leaving the upper part of the tuberous root exposed outside the soil. It will gradually stem and flower and adapt to the external environment, and then each year it will send out 1-2 new branches. These new branches will produce beautiful flowers and bear fruit. With this method, the tuberous root can be cultivated for as long as ten years.
2. Propagation by sowing
1. Timing
Manual sowing is generally chosen in mid-to-late April, so as to ensure that the four o'clock flower blooms in summer and bears fruit in autumn, and then the fruit is collected and plump seeds are selected from it. In addition, it can also self-sow and reproduce, at the time after the fruit matures.
2. Method
In April, when the weather is fairly clear, evenly scatter the seeds of the four o'clock flower on a sand bed, then keep the temperature between 15-20°C. Note that the seeds should not be sown in an open-field seedbed and then transplanted; they generally take root in 7-8 days.
After rooting, wait until the seedlings grow 2-4 leaves before planting them out. When planting out, a distance of 50-80 cm should be kept between the plants, and then they should be placed in a cool place for care. Carry out fertilizing, watering and so on according to the cultivation methods and precautions for the four o'clock flower.
3. Propagation by cuttings
1. Timing. Among the propagation methods of the four o'clock flower, cuttings are one of the more commonly used ways, but the choice of timing is relatively important; it is generally chosen in early stage,
2. Method. When using cuttings, how does the four o'clock flower reproduce? Take young shoots from the robust growing branches of the four o'clock flower as cuttings, then insert them into prepared substrate. The substrate is made by mixing garden soil, sandy soil and so on. After that, keep the temperature at 20°C and the substrate moist; after 10-15 days they will take root.

Recently some friends who are preparing to grow flowers asked me, how does the four o'clock flower reproduce? Is it the same as other plants? The editor tells everyone here that the propagation methods of plants differ, because they are all different living individuals. Below, the editor gives a detailed introduction to the propagation methods of the four o'clock flower.
The flowers of the four o'clock flower open from evening to early morning and close under strong light. In summer, if there is shade from trees, it grows and blooms well; under the scorching sun of midsummer, it often shows leaf loss. It likes a well-ventilated environment and has a mosquito-repelling effect in summer.

The four o'clock flower can be propagated by spring sowing and can also self-sow and multiply; it is usually propagated by seed. Using the small nutlets as the sowing propagation material, they can be sown directly in the open field in mid-to-late April. The suitable germination temperature is 15-20°C, and they sprout in seven or eight days. Because it is a deep-rooted flower, it is not suitable to sow in an open-field seedbed and then transplant. If conditions permit, it can be sown in advance into a cylindrical pot with an inner diameter of 10 cm, and after the seedlings are established, they can be removed from the pot and planted out.
The four o'clock flower is propagated by seed, and it is suitable to sow and raise seedlings in March-April. When the seedlings grow 2-4 leaves, plant them out, with a plant spacing of 50-80 cm as suitable. After transplanting, pay attention to shading. The four o'clock flower is extensively managed and easy to grow; just pay attention to appropriate fertilizing and watering. The four o'clock flower is a wind-pollinated flower, and different varieties cross very easily. If you want to maintain varietal characteristics, you should cultivate them in isolation.

In the north, generally in late autumn, the above-ground part can be cut off and the perennial root dug up, buried in a flower pot with moist soil and placed in a low-temperature room to overwinter. The next spring, continue cultivating in the open field; the plants establish quickly and bloom early. Although the growth of perennial-root plants is not as vigorous as that of sown seedlings, their tuberous roots swell year by year, and after 3 consecutive years they can grow into a brown tuber about 10 cm in diameter, with layered wrinkled skin and a hard texture.
In spring, the lower 1/3 of the tuberous root can be planted into a shallow pot, with the upper part of the tuberous root exposed, gradually becoming stem-like and adapting to the external environment. And, by shaping it according to its form, it forms a natural rock landscape bonsai. Each spring it sends out 1-2 new branches that bloom and set seed. After autumn, cut off the branches and put the tuberous root in its original pot indoors, keeping the potting soil slightly moist and storing it well. It can be continuously cultivated for decades, and the tuberous root will appear increasingly antique and vigorous, with a unique charm.
Growing flowers is a very character-cultivating thing. The above is some explanation about how the four o'clock flower reproduces and a detailed introduction to the propagation methods of the four o'clock flower. We also hope everyone will pay more attention to Huobao Nongzi Network and learn more agricultural information.

Cultivation methods of the four o'clock flower
1. Soil: It is best to choose fertile sandy and semi-sandy soil. Planting in slightly acidic soil with a pH value of 6 to 6.5 can make the root system dense and the growth vigorous.
2. Watering: Jasmine is not tolerant of drought, but it also dislikes waterlogging. In hot summer weather on clear days, water twice a day, once in the morning and once in the evening. If the leaves are found to be curled and drooping, spray water on the leaves to promote growth. In the rainy season, loosen the soil frequently so that water does not accumulate in the pot.
3. Light: Jasmine likes hot, humid, ventilated and airy environments and needs sufficient light. Jasmine is a light-loving plant, and its growth and development require sufficient light; long-day direct light is more conducive to its growth and development. With strong light, the leaf color is deep green, the branches are thick and strong, there are many flower buds, the coloration is good and the fragrance is strong; if the light is insufficient or it is too shaded, the leaf color is pale green and the leaves are large and thin.
4. Temperature: Jasmine is relatively sensitive to temperature and requires a warm, humid climate, and it can adapt to relatively high temperatures; but it is not tolerant of low temperatures and has poor cold resistance. When the temperature is below 10°C, jasmine grows extremely slowly, or even stops growing. It can sprout at around 19°C, and only above 25°C does it develop flower buds; at 30-40°C, flower bud formation and development are better.
5. Fertilizing: The high-temperature season of midsummer is the peak growth period of jasmine. Apply more organic fertilizer and phosphorus-potassium fertilizer, such as peanut cake powder, bone meal, superphosphate and multi-element flower fertilizer, twice a month.
6. Pest and disease control: Jasmine often suffers damage from snout moth larvae, scale insects and red spiders, with July to September being the most serious, often boring into and eating the flower buds. It can be sprayed with all-purpose powder or fenvalerate diluted with water 200 times, sprayed once every half a month.
7. Pruning: Jasmine grows very fast in summer and needs timely pruning. When pruning potted jasmine, keep 10 cm to 15 cm of the base to promote the growth of many thick new shoots. If the new shoots grow very vigorously, pinch the tips when they are 10 cm long to promote secondary shoots, so that there will be more flowers and the plant shape will be compact. After the flowers fade, promptly cut off the flowering branches to reduce nutrient consumption, and it can also promote the growth of new shoots, making the branches dense, the buds numerous and the flowers abundant.
8. Propagation: Cutting propagation can be carried out from April to October. Select mature and robust branches (preferably those of the current year), cut them into about 10 cm, remove the lower leaves, insert them into a pot with half sand and half soil, water thoroughly and cover with plastic film to maintain relatively high air humidity; they will take root in 40 to 60 days.
