Roses are sunlight-loving, cold-resistant, drought-resistant and waterlogging-resistant. The requirements for soil are not strict, but it grows well in fertile and well-drained neutral or slightly acidic sandy loam. Roses grow luxuriantly and are easy to manage. In spring, use thin human and animal urine to pour around the roots, pay attention to watering and drainage in summer, and apply some fertilizer around the roots in autumn. Propagation is mainly carried out by dividing plants, which can be carried out before germination in March or after defoliation in autumn, and the rootstock of layering method or grafting method can be rose or rose. The survival rate of cutting is not high, and it is only used occasionally. Single-petal roses can also be sown and propagated, either in spring or autumn.
Selection method of good seedlings:
Among the rose seedlings, there are "big seedlings" that are marketed in winter and "new seedlings" that are only available in spring. For beginners, it will not fail to plant from big seedlings, so "big seedlings" are recommended to beginners. When buying big seedlings, you should confirm the following points:
1. There should be 2-3 full branches thicker than pencils.
2. The color of branches should be slightly brown and shiny.
3. Try to touch the branches to feel firm.
4. The branches and roots are not infected with diseases.
The following flower seedlings should be avoided:
All the flower seedlings are young and thin branches, the green flower seedlings with dull branches, and the flower seedlings with loose and soft touch are not firm in the middle.
In addition, the flower roots will be infected with diseases. It is also important to carefully confirm whether the roots have tumors, complete labels and clearly indicate the variety names.
Cultivation place:
Roses like a cool and well-lit growth environment, and there should be at least 6 hours of sunshine every day to produce flowers with good quality. Its suitable growth temperature is 15-25℃, which is too high for the growth of roses. In addition, good ventilation is also very important. The hot, humid and poorly ventilated environment is easy to make rose plants suffer from various diseases, such as black spot and powdery mildew. At present, there are generally two kinds of cultivation places: gardens and balconies. Gardens are generally planted in sunny places, and at least the whole morning should be sunny for 2-5 hours; Choose a place with good drainage and ventilation; Mix thoroughly with humus soil or compost before transplanting. Balcony generally take effective drying measures; Laying curtains, don't put flowerpots directly on the concrete; To prevent the drainage ditch from blocking or leaking, we should also consider living near; Place it in the sunny place for 2-5 hours in the morning.
Soil:
Soil suitable for the growth of roses must be loose, well ventilated and well drained. Potting soil can be prepared with sandy loam, snake sawdust and vermiculite, while roses cultivated in the open soil must be planted in a place where there will be no water, and the soil should be turned loose before planting. For garden planting, in order to improve the state of garden soil during transplantation, holes are dug in some transplanted places to remove bad soil, and ruby, humus soil and dried cow dung with granular structure are mixed in the dug places. In the place where roses have been planted before, transplanting new roses may worsen the growth and development of roses. In this case, new soil should be replaced. The flowerpot should be planted with ruby soil mixed with humus soil and dried cow dung. The proportion of mixed soil is as follows: 6% ruby soil, 2% humus soil and 2% dried cow dung. It is simple and easy to use commercially available rose culture soil. It can also be used directly. In order to further improve courage and drainage, if the water retention is mixed with 2-3% ruby soil, the soil can be used to achieve the best state.
Transplanting of flower seedlings:
It can be divided into transplanting in the garden and transplanting in the planting box (flowerpot)
The key point of transplanting in the garden is that the flower roots spread evenly around. In addition, when transplanting, you must never add fertilizer to the soil. After transplanting, it is necessary to fully water the plants, and before the roots are firmly rooted, it is necessary to erect pillars to support the plants. Preparation supplies include buckets, plastic gloves, leather gloves, pruning shears, pillars, strings, name labels, small shovels, humus soil (or compost), shovels, etc. The main steps are as follows:
1. Remove the film covering the root. The flower roots are protected by protective materials such as sphagnum or peat.
2. Carefully remove protective materials and soil, and carry out operations while carefully confirming that there is no tumor at the root. Trim off about 1/3 of the roots.
3. Put the flower roots into a bucket filled with water and let the roots fully absorb water for 3 minutes to 1 hour, but be careful not to leave them for more than 24 hours.
4. Dig a planting pit with a uniform diameter and depth of about 6 cm, put the humus soil or compost into the soil, mix it thoroughly, and then pour it back to the upper part of the newly dug soil.
5. Transplanting flower seedlings. The key point is: put the flower seedlings in the center of the cave, so that the flower roots spread evenly around and spread out as far as possible. Incline slightly downward from the plant base to stabilize the roots.
6. Cover the extended roots with soil ... > >
question 2: how to plant roses, four methods. 1. planting methods of potted roses
1. equipment of pot soil. ① 7% garbage soil and 3% river sand. ② 6% of dry river mud and 4% of honeycomb cinder are mixed. ③ 7% vegetable garden soil, 2% honeycomb cinder and 1% river sand.
2. Time for serving. It should be carried out after defoliation in early winter or before germination in early spring.
3. Fertilization and watering. Potted roses are controlled by limited pot soil, so the requirements for fertilizer and water are strict. ① Generally, compound fertilizer which is convenient and hygienic is preferred, because compound fertilizer has various elements, and the combination of nitrogen, phosphorus and potassium is better. Each plant should be applied with about 2 grams each time (the amount should not be too much), and the soil around the basin edge should be deepened by about 1 cm with iron, and then the fertilizer should be applied and covered with soil. (2) watering is one of the basic tasks of flower cultivation, but it is often also the reason why plants are prone to death. Watering depends on the soil in the basin. When it is dry, it must be watered once. Too wet will easily lead to rotten roots. Change the soil of the basin every other year, and cut off the surrounding roots at the bottom of the basin when changing the basin, so as to make more flowers, bigger flowers and brighter flowers.
4, plastic pruning
As usual, pruning is not needed, and the old plants can be pruned with dense branches, withered branches and pest branches. Roses are blooming, pick them when they fail, and then bloom again, otherwise they will only bloom once.
Planting method of potted roses
5. Control of flowering period
As usual, natural flowering period is better.
For leveling land, choose the land with deep soil layer, loose layout and excellent drainage to create a rose garden, dig pits with a spacing of 5 cm and a row spacing of 15-2 cm, with a depth of 5 cm, and apply 1 kg of Tian She fertilizer or bio-organic fertilizer to each pit.
To choose a good seedling, you should choose a strong rose seedling, and the budding seedling should have 2-3 branches; Grafted seedlings require a well-developed root system, a stem diameter of 3-4 mm and a plant height of 3 cm, which should be planted with it, and the seedlings transported to other places should be dipped in pulp and packaged.
Fair close planting requires about 7 rose seedlings per mu. Because there were few seedlings in that year, 1,5-2, rose seedlings can be planted per mu in order to save land. In the next year, seedlings can be transplanted or sold, and the spring planting will be held in early spring before the roses sprout. Autumn planting is from October to December, and summer planting is held on rainy days with continuous rainy season.
Scientifically handle intertillage weeding. Because the seedlings are small, weeds are easy to grow. Weeding should be done in real time, so that the seedlings are not damaged and there is no grass. The connecting soil is slack. Fertilization is mainly based on organic fertilizer, and topdressing is carried out four times a year as usual. Pouring livestock manure water for the first time before and after the Bright Festival is called sprouting fertilizer, and watering is carried out in real time. In late April, human and animal manure was applied for the second time before bud pregnancy or flower picking to promote more and fuller buds; Top-dressing bio-organic fertilizer in May, and applying overwintering fertilizer in late autumn and early winter, so as to ensure the seedlings to overwinter peacefully. After flowering in June and dormancy in winter, the rotten branches, diseased branches and delicate branches are cut off to grow new branches. Careful pest control should be carried out in all stages of field management.
6, pest control
potted roses, the main pests are green worms and scale insects, green worms are easy to control, once scale insects attack, it is difficult to control, which will lead to the whole plant infected with insects and lead to diseases, so the control of scale insects is the focus of domestic roses. To prevent and control scale insects, we should put roses in a well-ventilated and well-lit place, cut off many branches of roses, and keep a few main branches to ventilate the interior. Keep the soil moist, but don't accumulate water. When white spots are found on the branches of roses, they should be scraped off with bamboo pieces in time. If it is serious, the whole branches or even all branches should be cut off directly, combined with spraying scale-killing drugs. Roses are not afraid of pruning, and the pruning of roses will be introduced below. Pruning is very important for roses to grow well and blossom a lot. Generally, when wintering, all branches should be cut off about 1 cm above the ground to ensure a smooth wintering. After the beginning of spring, new buds will sprout, 2-3 new buds will be selected, and the rest will be broken off by hand. When the new buds grow to about 1-15 cm, the top will be picked off by hand. After a few days, 2-3 new buds will grow on each branch, so that the plant type of the whole rose will be complete and compact, and water and fertilizer can be supplied to several branches in a centralized way, so that the flowers will be large and the number can be as you wish. After flowering, you can cut off the flowering branches and grow new ones soon. If you want to spend a lot, keep fewer branches and remove some more buds. If you want to spend more, hit the top several times. Roses consume a lot of nutrients when they bloom, so they should be fertilized in time before and after pregnancy.
Maintenance of roses
2. Maintenance of roses
1. Wrap with plastic film. After selecting satisfactory flowers, be sure to wrap them in bundles with plastic film to avoid losing water. Cut them as soon as possible after returning home and insert them in water to prolong the viewing period.
2. Glass vase, which contains about two-thirds of water, add a little salt and cut off each branch. >
Question 3: How can roses be planted without roots?
Roots of ramets of Sophora japonica have strong tillering ability, and the more vigorous the ramets grow. If the ramets are not divided, the plants will be scattered and affect their normal development, resulting in less or no flowering. Generally, the ramets should be pruned before the shading in spring or after the defoliation in autumn, so it is not necessary to prune the roses during the growth period. Generally, they should be pruned during the dormant period of defoliation in winter, leaving one third or one half of the robust branches. Get rid of the old branches, dead branches, diseased branches and weak branches, and promote the germination of new roots at the base. Rose flower buds are all planted at the top of branches, so they can only be thinned, not cut short. Each plant generally becomes old after 4-6 years and needs to be updated. Watered roses are shallow-rooted tree species, which are afraid of waterlogging and drought. In rainy season, attention should be paid to drainage and waterlogging prevention. In summer, the temperature is high, so it is usually watered once every 7 days, but it can't be excessive, otherwise it will cause root rot. Usually, you can water them appropriately, and increase the water permeability before and after flowering. Illuminated roses like sunny and dry environments, and it is not easy to bloom without sunlight. Avoid planting under a white wall. The sunlight reflection from the white wall will burn the leaves, which is also unfavorable to the formation of flower buds. The temperature cutting propagation should be carried out at 2-25℃. When it is higher than 35℃, the plants will be stunted and the leaves will be yellow easily. At MINUS 2℃, it can still overwinter safely. Roses should not be planted without roots.
Question 4: How to plant roses by inserting thousands, and how can we make them take root faster? Soak the rose branches with horseshoe-shaped bottom in water solution with rooting powder or white sugar for 6 hours for cutting.
Question 5: How to plant and maintain potted roses
Roses should use ordinary soil. After being broken, use a 2 mm ~ 4 mm sieve to screen out coarse grains. Those who plant roses for the first time can use clay pots. The clay pot has good air permeability and water permeability, which can make roses grow well. Generally, one branch of roses is planted in a 6-7 inch pot; Two or three branches are planted in an 8-inch pot; Plant four to five branches in a 12-inch pot. The clay basin is best in the form of a cone, that is, a deep basin with a large diameter at the bottom of the basin, which can make the roots flourish and the flowers plump. Pay attention not to fill the pot with too much soil, generally 1 cm ~ 2.5 cm away from the mouth of the pot, which is convenient for watering and fertilization. Make the roots fully contact with the soil after the pot is put on, and the seedlings newly put on the pot must be watered enough until the water seeps out from the drainage hole at the bottom of the pot.
second, potted roses need to be loosened frequently and topdressing should be done frequently. New potted plants must be fertilized after germination, usually starting in early March, but they should not be watered with thick fertilizer, and the concentration should be about 2%. Old potted plants can be fertilized with thick fertilizer twice in the twelfth lunar month, with a concentration of 5%, and then twice in March. In the future, apply 2% light fertilizer once or twice a week, especially after the flower camp grows, so as to promote the flowers to be big and beautiful. It should be noted that when the buds are exposed, fertilization should be stopped and more water should be given, otherwise deformed flowers will appear. If thick fertilizer is applied, it must be watered in the afternoon and diluted with a little water the next morning.
When watering potted roses, water them only when the soil on the surface of the pot turns white. Watering depends on the season and weather. Generally, long summer waters it in the morning, in the afternoon in spring and autumn, and at noon in winter. To prevent water accumulation in rainy days:
Water should be watered less in cloudy days and more in sunny days. In hot weather, water should be poured more often, even once every morning and evening. When watering, you must pour enough water, but the pot soil should not be too wet for a long time to prevent the roots from rotting.
Third, pruning
Pruning potted roses is very important. Old plants should be pruned around beginning of spring, and thick branches should be kept, depending on the size of the pot. It is better to leave 2 ~ 3 buds on each branch. Newly planted plants can be pruned at the same time as they are planted. The method is the same as above. When pruning, leave as few thin branches and cross branches as possible. During the growth period of potted roses after germination, it is also necessary to shape and thin branches from time to time to remove dense branchlets that affect ventilation < P > and light transmission. When the flowers bloom, they should be trimmed. Generally, 3 ~ 4 leaves should be cut off for the long branches. Cut off 1 ~ 2 leaves from short branches, and cut off 1 ~ 2 leaves in time if there is no bud, so that it can sprout in time. In short, you like plants that are short and full, and you need to prune them more; If you like plant height, just trim off 1 ~ 2 blades. After each blossom in the future, such pruning should be carried out to make the next blossom more diligent and colorful.
question 6: how to plant roses with roots? video cutting of roses is mostly carried out from July to August, and pot cutting and border cutting can be used. Choose two-year-old robust branches, cut 15~2 cm long sections as cuttings, each cuttings should have at least three leaf buds, the lower part should be cut into horseshoe shape, and the upper part should be parallel.
shade and sun protection should be provided after insertion, and water should be sprayed frequently to maintain a certain humidity and temperature.
It takes about one month to take root and become a new plant, and it can be transplanted after one year.
Question 7: How to plant roses by inserting thousands of flowers? How to make them take root faster? Soak the rose branches with horseshoe-shaped bottom in water solution with rooting powder or white sugar for 6 hours for cutting.
question 8: how to grow roses? You only need to do the following things well when planting roses:
A) Sunshine: Roses love the sun and fear the shade. If planted in a place with poor light for a long time, it will grow poorly or die of rotted roots (there is no photosynthesis to produce growth nutrients, and there is no evaporation to cause buds to wither, leaves to fall or roots to die), so it is suitable to plant on the balcony or in the morning sun.
