Is there any way to grow dark roses?

Flower color is not only related to the soil, the most direct reason for the flower color is the content of chlorophyll, anthocyanins, carotene and carotenoids in the flower. These variations are caused by a variety of factors, such as light time, moisture, and so on. When you say that you are cultivating dark roses, my method is to plant them in a sunny place, and the plants in the north and south also show different shades of color because of the distribution of light factors.

The color of the rose is magnificent, the fragrance is pleasant, and its ornamental value is similar to that of the moon season, but the fragrance is not as rich as the moon season flowers, and it is a ceremonial flower treasure.

The location of the open field cultivation of roses should be suitable for their growth and development. Before planting, apply well-rotted organic fertilizer as base fertilizer in the hole, and water enough water after planting. Roses prefer fertilizer, and generally apply fertilizer about 4 times a year.

Apply germination fertilizer once in early spring, apply flower fertilizer once in May, apply fertilizer once during flowering, and apply organic fertilizer again before winter, then the next year will have more flowers, big flowers, and fragrant taste.

In early spring, when the weather is dry, sufficient irrigation should be carried out to promote flower bud differentiation and prolong the flowering time. After the buds appear in spring, the side buds should be removed in time to make the nutrients concentrate on the development and growth of the top buds. During the period of growth and development, it is necessary to carry out frequent cultivation and weeding.

Roses are afraid of waterlogging, the water accumulation time is a little longer, the lower leaves are yellow and falling, and they will die in severe cases, so they need to be drained in time during the rainy season. A more aggressive approach is not to plant roses in low-lying areas of stagnant water to prevent waterlogging.

Pruning is an important part of rose management. Since roses bloom on the current branches, frequent pruning can lead to vigorous growth, colorful flowers, and longer flowering years. There are two types of rose pruning: growing pruning and dormant pruning.

Pruning during the growth period is mainly to cut off the residual flower stalk and remove the diseased branches, dead branches and weak branches in time after flowering. In the dormant stage, 4 5 branches per plant are left before germination in early spring, and they are shortened at a distance of 40 50 cm from the ground, and each branch is left with 1 2 lateral branches, and two buds are left on each lateral branch. A rose plant can live for more than 20 years, and the three-year-old plant blooms at its peak, but after 4 to 5 years it begins to decline, and the yield and quality of the flowers decrease, so it needs to be renewed.

The method is: for the rose garden that has been planted for 4 to 5 years, the old roots are turned out in winter, the diseased and insect branches and senescent branches are removed, and the overly dense and overly vigorous bushes are divided, or the senescent rose plants are cut off at the rhizomes in autumn and winter, and then the soil between the rose rows is ploughed, cake fertilizer is applied, and sufficient water is irrigated. In this way, although the next year does not produce many flowers, the next 2 to 3 years will be greatly improved.

In addition, it is necessary to pay attention to the prevention and control of pests and diseases.

When planting roses, the focus should be on the cultivation of rose plants, so that the branches will be dense.

Light and temperature.

Good growth is prompted by abundant sunlight. Both ground and potted plants should be placed in a sunny place, and they should receive direct sunlight for more than 4 hours a day. It should not be placed indoors in a low-light place for a long time.

In winter, enter the room and put it in a sunny place. It is suitable for growth temperature of 12-28 and can withstand low temperature of -20. In the Zhengzhou area, it is safe to overwinter in the open field.

Watering and fertilizing.

Apply an appropriate amount of organic fertilizer to the tree cavity before planting, and water thoroughly after planting. Ground-planted roses do not have strict requirements for water and fertilizer, and generally have 3 times of fertilizer. The first is pre-flowering fertilizer, which is applied in the furrow before the spring bud shade, and it is better to add humus to the well-rotted manure.

The second is post-flowering fertilizer, and the rotted cake fertilizer residue is applied after the flowering is extinguished to supplement the nutrients consumed by flowering. The third is winter fertilizer, and manure is applied after the leaves are fallen to ensure that the roses are safely wintered. Potted roses can be applied with thin fertilizer water for a long time in cattle, and applied once in 10-15 days after harvesting.

Roses are drought tolerant, and are generally planted in the ground without watering, and are watered once every 20-30 days in hot summer or spring drought. Water potted plants once every 2 days, and once a day in hot summer or spring drought.

Shaping and trimming. Generally, there is no need to prune, and the old plants can be pruned with dense branches, dry branches, and diseased and insect branches. Roses bloom, pick as they open or fail, and then open after picking, otherwise they will only bloom once.

Black rose, the Department of Rosaceae rosa, Pan Changzhi's professional scientific research of new varieties series, "China Flower News" title for Zhejiang flower farmers to challenge the world's breeding problems "black" moon season appeared in Shaoxing, farmers, green times, science and technology newspapers, Zhejiang Qianjiang Evening News and hundreds of newspapers across the country reported on this scientific research results, by ** TV station, Qianjiang TV, Shaoxing TV ** video black rose newsreel, for which Pan Changzhi applied for a patent to the State Forestry Administration, black rose has filled the domestic gap, Integrate scientific research with the market. **The industry welcomes enterprises and businesses with economic strength to join and cooperate.

The purpose of cultivating black roses is to cultivate true blue roses. Rumor and legend: "Five years of professional scientific research, has found the blue pigment of the blue rose, the blue pigment comes from the black, and after two or three years of breeding and cultivation can be scientifically researched to produce the world's recognized, truly alive, can pass on the next generation of real blue rose."

But in reality, blue roses are also non-existent. The so-called "blue roses" are all in the blue moon season.

Are you still dormant in winter? Wait a little longer.

Let me introduce you to the propagation method of roses.

Roses are mainly propagated by branches, and can also be propagated by strips, cuttings, grafting, and seeds.

1. Dividing propagation.

One year before the ramification, sufficient fertilizer and watering should be applied near the rhizosphere of the mother plant, and the soil should be kept loose and moist to promote a large number of root tillering. Because the tillering ability of roses is very strong, the mother branch is easy to wither after each new branch, so it is necessary to transplant the young branches near the rhizosphere to other places in time, so that the mother branch can still grow vigorously. Therefore, every year in November and December, after the plant has fallen leaves, or when the buds have just germinated in February of the following year, new plants that grow vigorously next to the mother plant can be dug from the large flower mound, each cluster has 2 3 stems, and the roots are planted.

After planting, it should be dried from 20 to 25 cm above the soil surface, and it can be cultivated into a cluster after 2 or 3 years.

2. Propagation by cuttings.

Before budding in early spring, select 1-year-old branches with strong growth and no pests and diseases, cut them into cuttings about 20cm long, and insert them obliquely into a cuttings made of Xinhe sand with a depth of 12 14cm, water them after compaction, and often maintain the temperature of the sand bed, take root after about 30 days, and transplant them after germination. It is easier to heal and root cuttings in sand beds, but it is necessary to build arched plastic shed cuttings in the sunny place in the greenhouse or in the field, and the management should be meticulous. Shooter cuttings are generally carried out in the rainy season, take semi-mature branches, cut about 20cm long in the middle and lower for cuttings, with 2 3 nodes and buds, obliquely inserted in the soil, watered after compaction, and transplanted after rooting and germination; Old cuttings are mostly carried out during the growing season in September and November.

3. Strip propagation.

In the rainy season in June and August every year, select the strong branches of the year, bend them into the soil, embed the wounds with soil clods after the soil part is carved, bury them in the soil, fix them with bamboo forks or branches, let the branches expose the ground, keep the soil moist, take root in 2 3 months, and separate from the mother plant in the spring of the next year, and plant separately.

4. Grafting propagation can be carried out with roses or moons as rootstocks.

5. Seed propagation of single-petal roses can be sown and propagated, and can be sown in spring or autumn.

You may be able to take a look at cuttings and strips.
