Culture methods and matters needing attention of rose

In China, rose is a favorite flowering plant. Their flowers are very bright and colorful. Common colors are red, white, yellow, and some are pink. In recent years, some new varieties will also produce mixed-colored rose flowers.

Rose is a kind of flower that many flower friends like to breed, and it is also quite common in daily life. They always bloom quietly and bring a lot of joy to flower friends. Compared with delicate roses and clear daffodils, rose flowers can be said to be very straightforward. When they are open, they are generous and fragrant, so that people will be very happy to see them.

Now it can be said that there are a lot of friends who like rose flowers, and many of them plant a few plants on their own balcony. However, in order to raise the potted rose well, friends still need to know some conservation skills. Only in this way can the rose flowers be cultivated well.

Rose culture methods:

The main results are as follows: 1. Rose flowers like to grow in an environment with sufficient light and good ventilation. Friends in the maintenance, you can put it on the south balcony, so that not only the lighting conditions are good, but also the ventilation conditions are good. However, friends can not let rose flowers directly exposed to the sun, otherwise their flowers will easily dry up.

2. Rose likes to live in a relatively humid environment, and friends need to keep the air humidity above 75%. When the air becomes dry, friends need to spray some water on the leaves and around the plant, which can increase the humidity of the air.

3. The rose grows very fast in spring, and friends need to prune it in time. The rose flowers bloom in May every year, and when the flowers wither, friends should cut off the remaining flowers and prune the branches properly. The purpose of this is to make the rose bigger and more beautiful when it blossoms for the second time.

4. Watering the rose is also something that friends need to pay special attention to. This kind of plant has a strict demand for water and likes to grow in moist soil, but it should not be too wet, otherwise it will be in danger of rotting roots. And do not let the plant grow in too dry soil, otherwise the root of rose is easy to wither. Therefore, during the growing period, friends need to often replenish water for the rose, so as not to affect the plant growth.

In order to maintain Chinese rose, we should pay attention to the prevention and treatment of diseases.

There are mainly several kinds of disease prevention:

(1) fungal infection:

Black spot: mainly infects leaves, petioles and tender shoots. At the beginning of the disease, purple-brown to brown spots appear on the front, and the enlarged spots are mostly round or amorphous dark-brown spots. Can be sprayed with carbendazim, methyl thiophanate, daconine and other drugs.

Powdery mildew: invading tender leaves, white powdery substance appeared on both sides, and the early symptoms were not obvious. five days after the appearance of 3Murray in the powdery mildew layer, the leaves showed water stains, gradually lost green and turned yellow, and caused leaves to fall off in case of serious injury. During the onset period, carbendazim and triadimefon can be sprayed, but the effect of Guoguang Inna is the best.

Leaf blight: most leaf tips or leaf edges invade, initially yellow dots, then rapidly expand inward into irregular spots, seriously damaged whole leaves withered up to 2 canker 3, the disease part chlorotic yellowing, brown dry shedding. In addition to strengthening the management of fertilizer and water, the diseased branches and leaves should be cut off in winter, the underground fallen leaves should be removed, the sources of initial invasion should be reduced, comprehensive control should be taken when the disease occurs, and fungicides such as carbendazim and methyl thiophanate should be sprayed.

Culture methods and matters needing attention of rose

Many novice roses are consulting the breeding methods and matters needing attention, hoping to find a way to raise roses from this article. Although this article is not a perfect article suitable for novice flower friends, however, the article contains the selection of rose varieties, the main points of daily maintenance, the prevention of diseases and insect pests, etc., is very worthy of flower friends to understand.

I. Variety selection

First of all, you have to choose the variety you want, there is no good or bad variety, only whether it is suitable for your rose, each rose always has its advantages, there is always a reason for its existence, do not blindly follow the trend, do not do the picture party, according to your planting environment to choose the variety you need most, the most suitable for you. Don't change this tree to another new variety before it has a good effect. Finally, one tree doesn't look good, and the new variety is updated too quickly. Some varieties need to be in the prime of life to have an amazing flowering effect, the seedlings may not be satisfied, but once shaped will surprise you. Be careful not to pursue new varieties blindly.

Yangtai people: if you choose those varieties that have a large number of flowers, bloom in many seasons, and the crown width of the plant is not large, you must first check the information, or else the flowers will become trees if you don't see them. In fact, the flowering nature of many materials translated into foreign languages is very uncertain, and the climate is different. You should refer to what others have planted. Can choose some small crown Austin rose, Fenghua rose, micro-moon, etc., not the balcony can only grow micro-moon, some small crown can also be, such as beauty, Oche Juliet, Miranda and so on quite suitable.

Balcony: similar to the balcony, but you can choose some shrubs, you can do flower racks, styles to grow small vines, you can also plant a few HT, but do not recommend classical roses and strong roses.

Courtyard: choose your variety according to the actual situation in the courtyard. If there is a fence, get a vine, a flower rack, a small vine, an arch, ah, a vine. The big fence is only one season, ah, multi-season hybrid, some season old roses are really good-looking, always give you a big surprise, and easy to maintain, easy to take care of. According to your favorite colors, plant a few strong flowers in the open place, one clump is very good-looking, and you can plant some HT ones densely on the side. Can be in the rockery edge, corner of a few old roses, strong fragrance, a large number of flowers, very spectacular, to make a real rose garden, ah, without these old roses. Although one season, but the opening time is very spectacular, enough to surprise for a year.

Specific application recommendations:

Arch: most people think of Fujimoto rose when they mention the arch. In fact, Fujimoto is not suitable. Fujimoto is very tall and grows indefinitely, which collapses the arch, which is my own. And under the vine is not easy to blossom, and many vines flowering is not good, there are not many fragrance. So the most recommended are Austin-like Fujimoto, Morris, Wickywood, Princess Margaret, Claire Austin, Tess, Gertru Jekyll, laughter Georgia and so on.

Fence: divided into general fence type and high fence, the height of the fence is the same as the arch. Choose Fujimoto on the high fence. If the fence is long, you can match it with several colors, multi-season and one season.

Scaffolding: if you only surround a column or something, it will be the same as the arch. If you need to climb all over the gallery, you can choose large Fujimoto, Longsha gemstones and alchemists.

Flower beds: just choose the low varieties, and then choose the ones on the balcony I mentioned above. generally, the flower beds are always with the fence and walls, and the flower beds are planted with these low ones, and then choose large shrubs above.

Potted plants: choose some varieties that grow luxuriantly and stretch horizontally, Austin's small shrubs, rich flower roses, micro-months are fine.

Variety enthusiast: it's hard to say. Everyone has different hobbies. Choose for yourself.

Collector: accept all kinds, as long as there is land, .

Second, purchase and deal with plants

Now the domestic start is late, and the level is not up to the level of foreign countries. Generally speaking, most of the small seedlings in Ouyue are only about half a year old. It will take some time for those big seedlings to be root-grafted, but this is a trend and necessary. Note that I am referring to the grafting of real roots, just like the imported bare roots, and grafting on the roses of cuttings is not in this category. This kind of aging is fast. If the rootstock sprouts, you'll get bored.

First of all, I would like to emphasize what a strong seedling is, either tall or strong, so I don't like to be asked how tall your seedling is. Vibrant roots and fresh leaves are more important than anything else. If the root system is good, there is no need to slow down the seedling. It grows directly, which is much faster than the slightly larger seedling with bare root. If the root system is not good, the new root will be re-issued during that period of time, and it will be dead if you don't hold on. Leaves are also very important. The root system absorbs water partly by the root hairs of the root, which provides power to absorb water according to the concentration difference. This is the principle of thick fertilizer and rooting. When the fertilizer is concentrated and the external concentration is high, all the water in the root is sucked out. Part of it depends on the evaporation of leaves to provide power for the root system to absorb water. If there are no leaves, the root system is not good, the water cannot be absorbed, it is dry to death, and it is useless to pour too much water. This is the principle that many autumn-bought ones with no leaves are dead. Also, only poles should not be cut in summer. Many students saw the disease and cut off the leaves. In the end, even the seedlings were cut to death. So I hope that flower friends will no longer ask me how tall the seedling is, it is really difficult to answer, it is not as high as high, if you want to be tall, it will be very fast without pruning, but this is not necessary, it depends on the overall situation. As long as Miao is healthy, it's okay to be young.

If the root system above is very good, there is no need to slow down the seedlings. In spring or autumn, you can directly go to the ground or change pots and put them in the sun. In summer, you can plant them in the evening, and then pour water thoroughly. If the sun is not particularly strong, you can bask in the sun the next day, and you can really put it in the shade for a few days. Pay attention to ventilation and scattered light, pay attention, do not be indoor slow seedlings, put for a week, and then in the sun, will die. If the soil ball is hard and there is no new root on the outside, you can peel off a layer of soil and let the root come into contact with the new medium, which is beneficial to the root. If you use peat seeds, it's not necessary to plant them directly, and you don't have to worry about nematodes.

III. Media

Although the requirements of the rose on the media are not high, basically anything can be planted, but a good medium can more easily raise good seedlings and reduce the investment in maintenance. the most reasonable proportion of potted medium is solid, air, moisture is 30%, 35%, 35% respectively, although it is impossible to strictly follow this, but you can choose a variety of media to mix according to this. The ratio of soil to solid, air and moisture is 50%, 25% and 25%, respectively. The fastidiousness of the media is too big, and there are many kinds of mixing when it comes to compiling a book. Probably according to their own materials around it, loose and breathable, the common recipes are: vegetable garden soil: coarse sand = 6:4, peat: perlite = 6:4, peat: loose scales = 6:4, not very strict. Oh, if you mix some organic fertilizer, it is better, organic fertilizer can slowly release nutrients by microbial decomposition, can strengthen the soil aggregate structure, make the soil loose, breathable and drainage performance is good. It is not very rigid, so it is recommended that some organic fertilizer should be added to the basin with vegetable garden soil. There is also a misunderstanding to understand that the base fertilizer is not the fertilizer placed at the bottom of the basin, so the fertilizer can be easily diverted with the water and can be mixed in the soil or applied in the topsoil around the root, and the root has a tendency to fertilizer. There is also a common sense that many people do not believe that potted plants grow better than ground plants. You don't believe it, hehe.

IV. Pot selection

Generally half a year seedlings can be transplanted to a pot with a diameter of about 16 centimeters, do not be greedy for convenience at one time for a large one, if the moisture is not well controlled, it will rot the root. Then plant for more than half a year and then change a larger basin, each time for a larger 10 cm basin.

5. Planting

When planting, hold the surface of the basin with the palm of your hand, and then turn it upside down, just take away the nutrition bowl and put it upside down in the pot or dirt pit, never pull it out directly. Be careful not to scatter the soil ball as much as possible, it will hurt the root system. A little pinch will break a lot of hair, because it is too fine, know the importance of root hair. After planting, water thoroughly in time, even if it rains, it must be watered again. Watering can make the root hair stick to the medium and absorb water directly, otherwise it will affect the absorption of water. In addition, some flower friends are afraid of freezing after watering in winter. in fact, there is a buffer around water, and it is more likely to freeze the roots if there is no water. So be sure to remember to water it in time after planting, and don't put it off the next day, if you don't water it, what about its root system this night?

Many flower friends report that the leaves turn yellow after planting, and then fall off, in fact, this is caused by a lack of water in a certain process. In order to reduce water evaporation and produce abscisic acid, the leaves fall off and want to go into dormancy, although it will not cause death, but it will affect growth. The same is true of many bare-root seedlings.

VI. Fertilization

First of all, understand what the plant needs, what is most needed is nitrogen, phosphorus and potassium, and then add trace elements, so as long as you supplement these, the plant is enough, and the organic fertilizer is also used, but the release is relatively slow. It can ensure the nutritional supply of plants for a long time, and can also promote looseness and so on. Chicken BB and bone meal are the main sources of phosphate fertilizer, but the fertilizer effect is very slow, phosphorus promotes flowering, so it is very good for rose, plant ash is the main source of potash fertilizer, promote branch health, bean cake has a lot of nitrogen and phosphorus fertilizer.

So these chemical fertilizers can be satisfied, rose is not to eat, a little chemical fertilizer is fine, the most simple and convenient is to use controlled release fertilizer, controlled release fertilizer is made according to the needs of plants, it is very convenient to use it once a year, the release rate of controlled release fertilizer will vary according to the amount of moisture and temperature, so you don't have to worry about winter and so on. If there is no controlled-release fertilizer, foliar fertilizer can be sprayed or poured in, and the water-soluble fertilizer can be diluted by a thousand times the liquid, once a week, to ensure that the plants are healthy and healthy. However, different seedling stage with different proportion of nitrogen, phosphorus and potassium ratio, seedlings and autumn with high potassium content, flowering with high phosphorus content, to raise the leaf nitrogen higher, but for simplicity, it is good to use a general-purpose one.

Personally, I would also like to emphasize that many people say that when planting seedlings, do not apply fertilizer, but this is under the premise that there is a small amount of fertilizer in the bare root or medium, for example, organic fertilizer is added, and if it is a new nutritious soil without fertilizer, the root system is also very good, so it must still be fertilized, oh, it is best to apply thin fertilizer frequently, or else the root system, ah, branches and leaves will not grow all of a sudden without nutrition.

There is also a misunderstanding that you can't apply fertilizer in summer. Summer is the fastest growing time of the year, when you feed him and make him grow fast, so it may cause dormancy and so on. in many cases, it is also the reason for the small blossoms in summer. the best thing in summer is to apply thin fertilizer frequently. Big water, big fertilizer, grow fast, the flowers are still big.

7. Pruning

You can talk about a lot of pruning. I'll add it later. I'll talk about it a little bit. In fact, you can understand it by looking at a picture.

According to this line of thinking, you can certainly develop a very plump ball. Many people always say that this is easy to install a tree and that is easy to install a tree. In fact, he is used to installing a tree, and the tree will not appear in the first place if it is trimmed like this. Just a few branches are still tied straight, how to promote the sprouting of bamboo shoots, he knows to keep growing up.

However, I would like to emphasize several winter overhauls. First, each type of rose pruning is different. Old roses have the pruning method of old roses, HT has HT pruning, micro-moon has micro-moon, and Fujimoto has Fujimoto. Probably remember that the old rose can be cut high and leave more branches, and the modern rose can keep three or five big branches per plant, cut to 30 to 45. The seedlings that have just been bought for half a year do not need to be cut in winter, leaving them to accumulate nutrients, with many leaves and fast growing roots, and the branches and leaves are proportional to the roots. In this way, it is easy to produce bamboo shoots in spring, and the leaves will not fall in winter. Wait for the shoots to come out before pruning.

How to promote the sprouting of bamboo shoots

If you want to get a thick and strong bamboo shoot bud, you can do two things: first, keep up with the nutrition, the seedling is very strong and fertile, and second, you can break the top advantage and press the branches askew and pull horizontally. although pruning can also destroy the top advantage, but after pruning will affect the absorption of plant nutrients, so try to retain as many leaves as possible, so you can definitely get a very strong shoot bud. Then, if the original branches are very thin and weak, you can cut them, and be careful not to make them too late, or it will freeze in winter when the buds come out.

IX. Diseases and insect pests

Insect pests, generally a little to see the need for medicine, oh, mainly red spiders, green insects

Red Spider: you should all know it. As soon as you see it, apply the medicine immediately. If there are not many seedlings, you can pinch it with your hands. If you can't, wash it with water. Take a spray can and spray him every day. Spray it for three days and you'll finish it. But spray the back of the leaves. If there are many roses and many worms, you can only be medicated. Avidaben can be used most often. If this doesn't work, you can change it for new drugs. It may be a little expensive, but the effect is very good.

Green worms, not many words pinch it, more words recommend the use of biological pesticides, bacilli, efficacy for a month, non-toxic to people, this is the best.

Aphids: usually can be treated with imidacloprid.

Diseases: mainly black spot and powdery mildew, which depends mainly on prevention, basically spraying alternately once a week to half a month at home, and a supplementary spray every time it rains.

Black spot: there will be black spots on the leaves, the surrounding will be yellow, if serious, the leaves of the whole seedling will be yellow and deciduous, which has a great impact.

Powdery mildew: there will be white powder on the leaves, and then the leaves will curl, this spring and autumn are very good hair, generally rely on peacetime prevention, once there is also very troublesome, mainly in the tender leaves, or directly cut the most convenient. However, there are several drugs that are very effective. After spraying for three days, the white powder hung up.

After powdery mildew was sprayed with fungicide, powdery mildew killed

10. Frequently asked questions

Black dry: mainly due to weak seedlings, poor root system, this is their own problem, the use of medicine is not effective, it is recommended that more ventilation, keep the medium dry.

Huangye: one is the yellowing of the old leaf at the bottom just after receiving it. This is due to the early aging caused by mail, which is not a big problem. The root system is proportional to the leaves, slightly damage the root system, need to reduce the number of leaves to balance.

On the other hand, the leaves are usually yellow, mainly caused by inadvertent dryness. Maybe you pour water thoroughly in the morning, but there is still a lack of water at noon. Although it recovers in the evening, you think it is all right, but it has already been hurt. After lack of water, he needs dormancy to reduce the loss. The most direct manifestation is fallen leaves. Or do it directly, don't water it right away, spray some water first, water it a little bit, and then water it when it recovers. Don't flood immediately after the big work, it will rot the root.

How to raise rose, the culture method and matters needing attention of rose

Rose, the four seasons bloom, is a common flower in the courtyard, garden, can make up for the seasonal vacancy, there are many people will raise rose at home, so how to raise rose, what are the breeding methods and points for attention of rose?

The rose is sunny, cold and drought-resistant, requires an environment with good drainage, good ventilation and shelter from the wind, strong adaptability and low requirements for soil.

The culture method of rose

Soil: rose has strong adaptability, and the general soil can grow, and the microstrip acid sandy loam with rich organic matter and good drainage is the most suitable.

Temperature: the best growth temperature of rose is 22: 25 ℃. When the winter temperature is lower than 5 ℃, it will enter the dormancy period. When the temperature is below-15 ℃, it will cause frost injury. The high temperature in summer lasts more than 30 ℃, which affects the quantity and quality of flowering.

Illumination: the rose is sunny and shines for at least 5-6 hours a day, otherwise it will affect the plant growth and flowering quality of the rose, high temperature in summer, if surrounded by high-rise concrete floor, pay attention to proper shade and sunscreen.

Watering: if the branches and leaves of the rose wilt, replenish water to the rose in time, pay attention to watering thoroughly each time; in addition, pay attention to ensure that the rose has sufficient water during the flowering period, but not too dry and wet, otherwise it is easy to cause falling flowers.

Fertilization: the amount of fertilizer required for rose is not high, so it can be fertilized properly in the peak growing season after winter, spring or May. Apply a little organic fertilizer to the root of rose in winter to enhance the cold resistance of rose in winter; before sprouting in March and spring, apply organic fertilizer to supplement nutrients; during the peak growing season after May, topdressing should be applied once every 10 days. The rotten and fermented fish juice and vegetable leaf juice can be mixed in the proportion of 3 parts of fertilizer and 7 parts of water, and the fertilization will stop in November.

Pruning: the rose usually starts pruning the remnant flowers and leaves in the middle and last ten days of May, which can enhance the plant growth. When pruning, it is necessary to prune the nails above the new buds, which is beneficial to the growth of rose plants.

Matters needing attention of rose

The planting site of the rose should not only have good air fluidity, but also avoid the wind; pay attention to dilution when fertilizing the rose, and the solubility of fertilization should not be too large, otherwise it is easy to burn roots; if you want the rose to blossom better, you need to cut off the old, weak and diseased branches in time to promote the vitality of the rose, but it should not be too heavy, otherwise it is easy to cause the death of the rose.

The above are the breeding methods and matters needing attention of the rose, it is necessary to pay special attention to: when pruning the root of the rose, do not trim too heavy, otherwise it is easy to cause the root absorptive capacity to decline, causing plant death.
