When do roses grow? A Brief Introduction to the Planting Methods and Cultivation Techniques of Rose Flower

Rose is one of the most famous ornamental plants in the world, and it has a long history of cultivation in China. After the introduction of rose in China in the 18th and 19th century, it crossed and backcrossed with the original varieties, and cultivated rose, perfume rose, wild rose and rose and other varieties. It has a very high ornamental value. Let's take a look at when the roses will be planted.

When will the roses be planted?

The rose can be planted all the year round, keeping the root system moist in the growing season and preventing cold in winter, but it is suitable from autumn defoliation to spring sprouting, and the best planting period is from autumn defoliation to freezing. In order to make the plant grow and enlarge the flower cluster as soon as possible, large holes must be planted with 1 meter long and 1 meter wide, 0.6-0.8 meters deep, or digging planting ditches with 0.6-0.8 meters deep and 0.8 meters wide. Plant application of organic fertilizer, calcium superphosphate, mixed with the soil and concentrated application in the soil depth of 0.2 to 0.5 meters, after planting, timely irrigation.

The Propagation method of Rose

Rose seed can be used for raising seedlings, but it is easy to survive by using tender wood cuttings in the same year in production. Valuable varieties are difficult to cut and can be propagated by pressing or grafting. Seedlings of asexual reproduction can blossom in the same year. For the seedlings used as potted flowers, the older branches of fine varieties should be selected, the seedlings should be raised by striping method, and attention should be paid to pruning the main buds and artificial dwarfing. For seedlings used as cut flowers, varieties that can form mother branches and colorful flowers should be selected to raise seedlings. Rose can also be propagated by tissue culture, water culture, ramet and other methods.

The planting method of rose flower

1. Soil: the rose flower is not strict in soil, resistant to drought and barren. It is most suitable to grow in deep, loose, fertile, moist and well-drained soil, and it can also grow normally in clayey soil. Whether planted in the ground or potted, the cultivation soil of rose flowers should be fully mature sandy soil as the best.

2. Illumination: the rose is a light-loving flower, which likes plenty of sunshine, and it is also resistant to semi-shade, cold and adaptability. it is suitable to be planted in all parts of the south except for the severe cold in winter. Roses should have enough sunshine during their growth so that they can flourish and blossom more.

3. Watering: roses like to be wet, afraid of being wet and avoid waterlogging. From the rose sprouting to blooming, you can properly irrigate some more water, with the soil moist but without stagnant water as the best. After the rose blossoms, you should reduce the amount of water, dry and wet the soil when watering, and pay attention to drainage and waterlogging in the rainy season to avoid stagnant water rotting the roots.

4. Fertilization: roses prefer fertilizer and are resistant to barren. Liquid fertilizer dominated by nitrogen can be applied once or twice in March to promote the branches and leaves of roses to flourish. In April and May, fertilizers mainly based on phosphorus and potassium can be applied 2 to 3 times. In order to promote the rose flower to have more pregnant buds and blossom, and then apply rehabilitation fertilizer again after flowering, then you can stop fertilization. Roses need to cultivate soil and fertilize once a year in winter.

5. Pruning: pruning and shaping is an indispensable process in most flower breeding, and natural roses are no exception, especially when cultivated as potted flowers, we should pay more attention to pruning and shaping. In general, adult roses are pruned before germination every spring, and the amount should be moderate to ensure that the branches of the roses are dense and beautiful. The old branches and dense branches of roses should be often trimmed every winter to maintain good light transmission and ventilation so as to reduce diseases and insect pests.

How to cultivate the rose, when will the rose bloom?

Rose is a more common plant, with pink, red, white and other colors, more varieties, with a high ornamental value. Roses give off a unique fragrance, which helps relieve nervous tension and stretch the body and mind. It can also be used for the treatment of neurological diseases. Buy a pot of this kind of plant at home, while enjoying the leisure time, experience the visual pleasure, more refreshing and relieving fatigue, make people have the motivation to continue to work and study, and feel at ease. Today, I will briefly introduce when the rose blossoms will bloom and the cultivation methods. How to cultivate roses seed stripping is generally carried out before sowing, can be separated by manual or machine peeling, and then rinse the seeds with clean water and air-dry indoors. The seeds can be sown after they are dried. If the seeds cannot be sowed immediately, they can be refrigerated in the refrigerator for a short time, but do not be too dry, otherwise the seeds will be affected. Sowing is usually carried out from March to April. Covered with plastic film or set up a plastic shed on the sowing bed after sowing, the seedlings can be unearthed 10 days later, such as plastic film mulching. After most of the seedlings are unearthed, the plastic film should be removed in time to prevent the seedlings from burning. At the same time, water should be irrigated for the first time and trickle flow irrigation should be carried out to prevent the silt from burying to the seedlings. Water can be irrigated every 10 days in the future. When the seedlings grow the first pair of true leaves, they can be irrigated every 15 days. At the same time, attention should be paid to loosening the soil and weeding, and one-time interseedling and seedling setting can be carried out when the seedlings grow to the height of 5-6cm. Before planting, ditches should be opened to apply base fertilizer. Water regularly in spring. New long branches grow from the roots every year and blossom on their side branches in the same year. After flowering, the branches that have flowered should be cut off. The multi-flowered rose is very resistant to cold and fertilizer. In the process of growth, attention should be paid to drainage and waterlogging in the rainy season, and fertilization should be applied for 3 times to promote the unflowered branches to blossom in the following year. Disinfectants can be used to disinfect the soil before seedling planting. At the same time, mature organic fertilizer should be applied to the growing rose. after planting, base fertilizer can be applied once a year in late autumn to facilitate growth and flowering. Be sure to keep the soil moist before flowering, if drought will affect the number of flowers; pay attention to drainage and waterlogging in the rainy season, if too much water is easy to rot roots. During the bud period, it is appropriate to apply 1 Mel twice thinned cake fertilizer and water, if applied, the flower color is good and the flowering period is long. Pruning is generally carried out before the germination of leaf buds. During pruning, the main branch retains about 1.5m, and the lateral branch retains three or five buds at the base. At the same time, it is necessary to remove dead branches, weak branches and branches of diseases and insect pests, and cut off branches that are too old and too dense. The main diseases and insect pests in rose culture are powdery mildew and black spot, which can be sprayed with 1000 times of methyl topiramate wettable powder. Insect pests are harmful to aphids and diamondback moths, which are sprayed with 2000 times of deworming essential oil. Powdery mildew generally appeared in the disease center from the end of March to the beginning of April, and the diseased plant rate increased rapidly with the gradual rise of temperature after the middle of April, which led to a pandemic under suitable conditions. When the black spot is serious, the lower leaves of the plant are withered and yellow, and the leaves fall in the early stage, resulting in the death of individual branches. For the control of aphids and diamondback moths, various means should be used to stop their harmful activities and protect plant growth. When the rose blossoms usually blooms from May to September every year, and the order can be as long as half a year, but in recent years, due to global warming caused by Greenhouse Effect, roses begin to bloom in April or even March in some places. Therefore, flower lovers who want to enjoy the flowers should seize the time so as not to miss the viewing period.
