How to plant rose seedlings: from planting to maintenance

Speaking of rose seedlings, many flower friends can't help but make complaints about what I do not have. Or is it always stiff? There are many factors that cause this situation, but most of them are attributed to improper management. There are also some factors that may lead to the purchase of diseased plants and the lack of experience in raising seedlings, which eventually lead to seedling stiffness and even death.

In addition to the above self factors, of course, there are many external factors, such as light, ventilation, permeability of soil matrix, unreasonable combination of watering and fertilization, etc. it is essential to learn to use these factors. This article will bring you about how to plant rose seedlings, friends in need must not miss oh~

How to plant rose seedlings 1. About soil and pots: before buying roses, you should prepare soil and flowerpots in advance. Some flower friends buy seedlings that have nothing at home, and then rush to take what they have. Many soil is very hard and hard, and you don't want to use it directly. Others use coconut bran directly. Coconut bran is too water-saving, so it's easy to stuffy roots It's a miracle to keep alive~

Soil is the most fundamental element of flower cultivation, so we must choose it well. Clay (not garden soil) is not recommended. Other soil can live. The medium must be loose and breathable. It is not recommended to use too hard soil and too water retaining medium. Of course, I don't think it should be used well for too rich soil. It is better not to use it in the early stage of planting when the roots of seedlings are damaged during express delivery. So far, I can still make clay and seal it for a few months. It's too tired to make clay, but it's economical. I always use coconut powder brick, which is light and simple.

2. In addition, flower pots are also very particular. The best pots are soil pots, followed by plastic pots, followed by ceramic pots. Of course, experts are another matter. As long as the medium is well matched, any pot can raise seedlings very well.

3. After the pot and soil are prepared, the seedlings can be planted. When planting seedlings, it is recommended that you should plant shallowly. The advantage of shallowly planting is that it is beneficial to the growth of root system and prevents root clogging.

4. After planting, the first watering must be done until the bottom of the pot leaks. It's better not to dry the seedlings in the early stage of maintenance, but to dry them in the morning and evening in summer. The seedlings should be watered without drying. It is not recommended to apply fertilizer to the seedlings in the early stage. It is OK to apply fertilizer to the seedlings when the root system of the seedlings is slow and strong.

How to plant rose seedlings

Daily maintenance and watering of rose seedlings:

There is also watering, the old saying "no dry, no water". Add a few more sentences, according to their own environment, small and medium-sized basin environment (soil evaporation, seedling situation is big or small,). If the soil is sticky and not too loose, the root setting water must be poured thoroughly.

This is especially true for large and medium-sized seedlings, such as sunflower. If some sunflowers have no spirit the next day, they should bask in the sun in time, and in the case of good ventilation, they must be watered for the second time in time, but do not water too much, especially when the rose has already "taken" the pot, then they should be dried and watered thoroughly, and the root setting water should be sufficient.

illumination:

Generally, people who buy flowers and flowers always say: it's OK for roses to bask in the sun and the moon. But when you go home and do what he does, you will probably die in battle. Whether you buy flowers online, you still need to see the sun step by step. We can't make the terminally ill patients a little better. Suddenly let you eat a big meal, no one can stand, my general practice is to come back from the Internet flowers, watering water, began to put in a slightly weak light place. Waiting for Rose "service" basin, and then moved to the delicate light, light slightly strong place, everything slowly.

Temperature: temperature and light have a great regulating effect on the growth of plants, such as germination, growth, flowering, dormancy, etc., which is a habit gradually formed by plants adapting to the geographical and climatic environment for a long time. If the temperature and light are abnormal, the growth of plants will also have corresponding abnormal changes. The suitable temperature for Rose growth is 15-30 ℃. The temperature rises in March and April every year, and the rose begins to sprout and enter the growth and flowering period. In the middle and late November, the temperature gradually decreases, and then it begins to enter dormancy. In summer, when the temperature is too high, lasting more than 35 or 36 degrees, and the light is very strong, it will enter a short dormancy. In the south of the Yangtze River, winter roses can safely spend the winter outdoors. The rose should be allowed to spend the winter outdoors, so as to get a good dormancy, so as to lay a good foundation for the germination and growth of the next spring;

Humidity: roses like warm, humid environment, strong adaptability, suitable for growth in Jiangnan area. If the humidity is too high and the temperature is too high, it is easy to produce bacterial diseases; if the humidity is low, the air is dry, the temperature is high and the air is not ventilated, it is easy to produce red spider and other insect pests. The above can be prevented and treated by human physical intervention;

Ventilation: all plants grow in the wild for a long time, like good ventilation. Therefore, flowers should be placed outdoors in the growing season. If they are dormant in winter and the temperature is too low, they should also have good light and ventilation in the south;

How to maintain rose seedlings

Pruning: in the daily maintenance of rose, pruning is a necessary means to maintain good plant type, adjust plant nutrient balance, enhance plant resistance, reduce diseases and pests, and improve flowering quality. Especially for balcony potted flowers with limited space and nutrients.

The pruning of Chinese rose should be combined with the different stages of the year and the growth and flowering habits of Chinese rose. The author thinks that the pruning of rose can be divided into light pruning in growth stage and heavy pruning in winter dormancy stage. The growth habit of rose is strong germination ability, the longer the branch is, the thinner the flower is. Therefore, from March and April to the end of November, rose should be cut lightly during its growth and flowering. In March and April of the first spring, according to the nutritional status of the plant, leave the strong and remove the weak, cut off the thin and weak diseased branches, extra bore branches (inward growing branches) and Cross branches, leave the branches from the base upward, leave 2-3 bud eyes for the thick ones, leave 1-2 bud eyes for the general ones, and cut off all the other upward branches except the old leaves before last year. In order to reduce unnecessary nutrient consumption, ensure the nutrient supply of the remaining bud eye, sprout strong buds. Only strong buds can produce strong branches, and only strong branches can produce standard flower patterns. After germination, growth and flowering, flower branches should be subtracted in time to avoid nutrient consumption. After the flower branches wither, 2-3 bud eyes are left according to the branch thickness, plant type and bud eye direction, and all the above are cut off. The top bud eye should be outward. After about a week, 1-2 of the 2-3 bud eyes will germinate again, grow branches, bloom and prune. And so on and again. Under normal circumstances, the time from germination to flowering is about 30-35 days, which is also the origin of the name of rose. After entering autumn and winter, the rose grows slowly, and begins to dormant with the decrease of temperature. In winter, heavy pruning is usually carried out from the end of December to the beginning of February, mainly to cut off all the weak branches, leaving only a few strong trunks (about 15-20cm in height), with 3-5 bud eyes for each trunk according to the actual nutritional situation, the top bud eye facing outward is better, and the rest upward are also cut off. The purpose is to control the plant type and height of potted rose during the next growth and flowering period, concentrate nutrients on strong branches and sprout strong buds or shoot buds;

Pest control

Insect pest;

Generally, if you see it a little bit, you need to apply medicine. It's mainly red spider and green worm,

Starscream: you should all know it. When you see it, you can apply the medicine immediately. If you don't have many seedlings, you can pinch them with your hands. If you can't, you can wash them with water. Take a watering can and spray them every day. After three days, you can finish the washing, but spray the back of the leaves. If there are too many roses and insects, you can only apply the medicine. Generally, you can use avidaben, which is the most widely used. If it doesn't work, you can replace it with a new drug. It may be a little expensive, but the effect is very good. You can contact me about this.

Green insects, if you don't have much, you can pinch them. If you have more, you'd better use biological pesticides and bacilli. They have a month's efficacy and are non-toxic to people. This is the best.

Aphid: it can be treated with imidacloprid.

Diseases;

It's mainly black spot and powdery mildew. It depends mainly on prevention. Basically, the family sprays it alternately once a week to half a month, and every time it rains, it needs to be sprayed again.

Black spot: there will be black spots on the leaves and yellow around them. If it is 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 will be very hair, generally rely on usual prevention, once there is also very troublesome, mainly in the tender leaves, with or directly cut the most convenient. But there are several drugs that are very effective. After spraying for three days, the powdery mildew hung up. After spraying fungicide, the powdery mildew was killed
