Raise a desert rose that is simple and beautiful.

Raise a desert rose that is simple and beautiful.

There is a kind of plant, it has a beautiful and elegant name, and a natural cute and naive form, it has a big belly and can tolerate the extreme heat of the world; it accumulates and blooms abruptly, and bright flowers bloom on the fat roots. Yes, it is the desert rose, what flower friends call a "silly girl". Let's take a look at its popular science card first.

Although it is called the desert rose, it is not related to the rose. It is indeed a succulent plant. Its shape is very characteristic: simple leaves alternate, Obovate, tip acute, 8-10 cm long, 2-4 cm wide, leathery, glossy, dark green ventral, gray-green back, entire. Raceme, terminal, with more than 10 flowers, trumpet-shaped, 6-8 cm long; Corolla 5-lobed, with rose, pink, white and complex colors, seeds with white pilose.

Desert rose belongs to the genus Apocynaceae, which is native to Kenya and Tanzania in Africa. There are 5 wild original species in this genus, which have been artificially cultivated and propagated. At present, more than 15000 species have been registered, which is one of the plants with the most varieties in the world. Desert roses have been introduced into China since the 1980s, but they are only planted in few areas. It is only more than ten years since it was really used in potted plants. So many people, even senior florists, will be shocked to see it for the first time: there are such flowers in the world? Soon this kind of novelty-hunting mentality will give birth to a strong desire to have a tree on the desk. So, how to raise a desert rose?

The propagation methods of desert roses include sowing propagation, cutting propagation, strip propagation, grafting and so on, but because the asexual propagation method can not grow thick and thick rhizomes, which greatly reduces the ornamental value, so generally use sowing methods to propagate and cultivate radish-like Kawayi roots, and then use the method of split grafting to graft different varieties and flowers on the same plant in the growing season. Improve the ornamental quality of its flowers.

Desert rose seeds on the market are generally divided into double mixed color and single mixed color. Individual merchants have seeds that are detailed to so-and-so, but the price is slightly higher. In fact, the variability of desert rose is very strong, and the sowing seedling character is not necessarily a female parent character, especially the double-petal varieties have a certain atavistic proportion, so the double-petal seeds are not necessarily double-petal varieties. In spite of this, watching the small desert roses take off their hats and grow into radish heads from furry seeds and bloom stunning flowers, many flower friends are infatuated with it and embark on the sowing road one after another.

The way to sow desert roses is actually very simple:

1. The choice of matrix and utensils. The matrix can choose loose and breathable fine sand or coconut bran, and the special soil for growing succulent plants is also excellent. If the sowing soil is relatively dry, it can be mixed with a small amount of water until the color of the soil becomes darker, and the state of "hands grasping into a ball, hands loose" is just right. The substrate should be disinfected before sowing, which can be heated at high temperature or potassium permanganate. Sowing utensils, a large number of seedlings can be raised with a hole plate, family breeding can use ordinary flowerpots.

two。 Seed placement and soil mulching. The long seeds are arranged horizontally on the paved substrate and gently covered with a layer of original matrix. The thickness of the covered soil is based on the principle of covering the seeds, which should not be too thick, otherwise the germination rate will be affected.

3. Watering and placement of seedling pots. The first watering should be drenched thoroughly, and if the seeds are washed away by watering, the seeds should be gently covered with sand. In addition, the basin filled with soil can also be immersed in water to ensure that the water can be felt by gently pressing the surface of the soil after soaking. After sowing, it should be placed in a cool, ventilated place where scattered light can be seen, and do not have direct light.

4. Germinate and moisturize. Before germination, seeds should be moisturized and properly sprayed with water. Usually after 3 or 7 days, the buds of small desert roses will break out of the earth one after another in small hats. After sprouting, it is usually watered every 2-3 days, or you can see that the topsoil is dry and then watered.

5. Light and other things. Desert roses grow vigorously in summer. generally speaking, true leaves begin to grow more than ten days after germination. When the seedlings of desert roses grow 3-4 pairs of true leaves, they can be transplanted into a pot and slow down a little after transplanting. You can pull her out to receive the baptism of the sun.

Normally, desert roses take 1 to 2 years from sowing to flowering. Flower friends who are eager to see flowers usually enjoy the fun of sowing and buy adult plants to enjoy the flowers. At present, the desert roses with better quality in the domestic market mainly come from the grafted desert roses in Taiwan. Taiwan desert roses have formed a mature breeding, grafting production, sales and logistics system, with a wide variety of varieties and colors. Some varieties such as' fragrant concubine 'and' peach 'also have fragrance to ensure that flower friends choose dazzling and shout chopping hands …...

Then, you must ask the second question: how to maintain what you bought from the Internet or major flower markets?

After the bare-root seedlings purchased on the Internet are received, the leaves are usually trimmed so that there is little left. It doesn't matter, squeeze its big belly with your hand, and contact the seller to deal with it if your stomach feels weak. If the stomach is hard, then OK, rest assured to boldly basin it. Flowerpots should choose shallow pots with good air permeability to facilitate root respiration and to control the frequency of watering. The basin soil should choose the sandy loam with loose ventilation and good drainage, and the loose sand and rotten leaf soil can be used together. If it is a mature seedling with the original pot and native delivery, it is best to slow the seedling for a few days and wait to see the new leaves grow out before changing the pot.

Desert roses like high temperature, dry and sunny environment, resistant to extreme heat, not cold, drought, and avoid dampness. Do not pour too much water each time, otherwise it is easy to cause root rot and branches grow excessively. Many beginners can not grasp the frequency of watering, as soon as they see that the topsoil is dry, they roar to water, often their desert roses are not killed by drought, but by waterlogging. How to control the amount of water scientifically and reasonably? It is suggested that beginners can insert a chopstick into the basin soil and pull it out before watering. If the bottom of the chopsticks is dry and then watered, remember that the bottom soil is not dry or watered. At the same time, you should pinch the big belly of desert roses from time to time. Once you find that it becomes soft, it is very likely that the water is too big. The cultivation of desert roses must have enough sunlight and ensure ventilation, otherwise it will affect the growth and flowering quantity. When the winter desert rose enters the dormant period, the leaves will gradually fall off, which is a normal reaction. At this time, it is necessary to reduce the watering frequency, keep the soil dry, and pay attention to ventilation and heat preservation to prevent frostbite.

Although the desert rose is more tolerant of barren, proper fertilization can make her grow faster, grow more luxuriantly and brightly colored. During the peak growth period in summer, phosphorus and potassium fertilizer should be supplemented once a month on average. At the same time, in order to ensure full growth, it is best to change the basin of desert roses once a year, and some long-term base fertilizer should be properly applied when changing pots. Rotten bean cakes and bone meal are the best choice. But should pay attention to avoid fertilizing too much, otherwise it will cause fertilizer damage, resulting in leaves yellowing.

The problems of yellow leaves are easy to occur in the growth process of desert roses, which may be due to too much watering, poor ventilation, too concealment, too much fertilization or diseases and insect pests. Once yellow leaves appear, watering should be controlled immediately, fertilization should be suspended and placed in Yang. Where there is enough light, then look for the cause and prescribe the right medicine to the case.

In addition, we need to remind you that the whole desert rose plant is poisonous, of which its milk is the most toxic, but there is no problem with indoor cultivation, so don't eat it by mistake. Of course, desert roses taste so bad that they won't eat too much even if they are eaten by mistake.

In fact, compared with delicate peonies and water-loving gardenia, the maintenance of desert roses is very simple. As long as you don't pour water too hard and give it plenty of sunshine, it can blossom brilliantly and is very suitable for lazy flower friends. This can be seen from her nickname "silly sister": "you raise foolishly, I live foolishly". Desert roses can blossom every year as long as they are properly maintained.

Think about the lovely and beautiful desert roses that bloom on your desk all the year round. Is it a delightful and relaxing thing? Raise a tree quickly!
