Those who know more about the cultivation of white roses are 35

Roses are light-loving, sun-loving, resistant to severe cold and drought, and do not need special protection against frost in the northern winter. As long as there is no major drought, it can grow without watering (referring to ground planting). The soil requirements are not strict, and generally the more fertile soil can be managed properly to make the growth vigorous, lush and leafy, and good flowering.

Roses should be planted in the fertile loam soil of the field and the edge of the ground with good ventilation and sunshine and watering and drainage conditions, and an appropriate amount of organic fertilizer should be applied to the tree cavity before planting, and watered thoroughly after planting. Ground-planted roses do not have strict requirements for water and fertilizer, so they should be watered and fertilized reasonably according to the needs of the plants, and a new high-fat film should be sprayed to protect fertilizer and moisture.

Fertilization in summer should be diligent, every 15 20 days need to be applied, and after fertilization, it should be watered in time to prevent seedlings from burning. Spraying flowers at the bud stage can promote strong flower buds, hypertrophic petals, bright flower color, rich floral fragrance and prolonged flowering period. Pruning should be done in autumn to prevent overgrowth, which will affect flowering and plant appearance.

There are many aphids in roses, and we should pay attention to prevention and control. During the hibernation period, it can be combined with base fertilizer and irrigation of overwintering water to lay the foundation for the stable and high yield of flower buds in the coming year.

…The first time I heard that the rose planting method is also divided into colors.

To be honest, I don't think it's realistic. If you start planting from cuttings or seeds, even if you want to bloom in four months, you have to carry out strict light control, temperature control, water and fertilizer management, and novices are basically useless. Even if it blooms, the plant type and blooming product are not good.

The feasible way is to buy seedlings for a year and raise them until they bloom.

If you really want to try it, you can consider using some hormone-containing flower fertilizers, such as flower treasures. In addition, the light is compensated with special planting lights after sunset.

1.Characteristic. Rose is a woody perennial plant of the family Rosaceae, with bright flowers. It is suitable for growing in most areas of China, and is suitable for growing in fertile, well-drained slightly acidic soil; It likes light, is hardy of cold, drought, moisture, and shade.

2.Cultivation management. First, choose cold-tolerant varieties that are suitable for cultivation in the north.

1) Fertilization. Because roses like fertilizer, apply enough organic fertilizer - farmhouse fertilizer as base fertilizer when planting, fertilizer twice a year, fertilization in October every year can play a role in heat preservation, full plant nutrients, and new branches, and fertilization in February of the next year to promote thick branches, hypertrophic flower buds, hypertrophic flower buds, and many flowers. The flowering period is 5 to 11 months, so the flowering period can be applied at any time according to the flower and leaf color.

2) Moisture. In early spring, roses sprout one after another, and should be fully irrigated to facilitate the timely delivery of nutrients by plants, promote flower bud differentiation, and prolong the flowering time. During the summer flowering period, it is necessary to control watering, which is the secret of good flowering, keep the soil moist, not waterlogged, otherwise the lower leaves will fall yellow, and the rainy season should be drained in time.

3) Prune. Pruning in production management is divided into flowering pruning and dormant pruning. Flowering pruning:

After the first flowers are open and harvested, they are cut 15 to 20 cm above the base of the flowering branches to promote the emergence of new branches, and the second flowering is more and of good quality. Dormant period: Retain strong shoots before germination in early spring, cut 1 2 side branches at a distance of 40 50 cm from the ground, and leave 2 buds on each side branch.

4) Rhizosphere soil. 80% of the root system of the rose is the horizontal root, it is very important to soil the base of the rose after the rose leaves fall or in early spring, the thickness of the soil is generally 4 8 cm, which not only thickens the soil layer of the flower bush, promotes the growth of the root system, and increases the soil humus after the fallen leaves and weeds are buried in the soil, and the diseased leaves are buried in the soil at the same time, which also reduces the spread of pathogens.

5) Reproduction. It is mainly based on seed seeding, dividing and cuttings. To propagate by seed, the fruit is harvested in the autumn of the first year, stored in sand, and sown in the open field before freezing, and the seedlings can emerge in April of the following year.

Branch cuttings can be carried out in the rainy season, the cuttings are selected from strong mature small branches with a diameter of about centimeters, remove the tender shoots, cut into 15 cm long, with 2 3 buds, directly into the soil 5 cm deep, and water once after cutting.

3.Pest and disease control. Prevention is better than cure.

Keeping roses strong increases the plant's resistance to pests and diseases. It is forbidden to apply excessive nitrogen fertilizer, the plant grows, and it is easy to infect pests and diseases; Pruning roses should keep the plant fully developed, which is conducive to ventilation and light transmission; Once the diseased branches appear, they should be pruned in time, and the pruning tools should be disinfected with alcohol or bleach solution. When the pests and diseases are serious in special years, chemical control methods can be appropriately adopted.

In order to prolong the opening time of white roses, hydroponic maintenance can be adopted, and the flower branches need to be pruned before hydroponics; For the hydroponic method, a long-necked vase needs to be prepared, disinfected and poured water, and then the branches are inserted into the bottle; In a warm environment, the room temperature should be stabilized above 20 to maintain the normal growth of the plant; For fertilization methods, it is necessary to spray preservatives on the flowers once a week.

In order to prolong the opening time of white roses, it is recommended to use hydroponic maintenance, use sterilized sharp scissors, and prune all the leaves on the flowers to reduce unnecessary nutrient consumption. Then prune the bottom of the branch into a 45° angle to increase the water absorption area of the branch and make it better absorb water.

When hydroponics of white roses, it is necessary to prepare a long-necked vase, sterilize and disinfect before use, and pour two-thirds of the water, and then insert the branches into the vase, and in the process of later maintenance, the water needs to be changed once a week to avoid poor growth of the plant.

The white rose itself has poor cold tolerance, suitable for growing in a warm environment, during the growth of white roses, if the ambient temperature is lower than 0, it will make the leaves and flowers frostbite, and the situation of wilting and falling. Room temperature should be stabilized above 20 degrees Celsius to maintain normal plant growth.

White roses consume more nutrients during the growth period, and in the process of maintaining white roses, it is necessary to spray preservatives on the flowers once a week to prolong the freshness of the flowers. And in the process of changing the water each time, you can pour crushed aspirin powder into the bottle to make the white roses grow more vigorously.

First of all, cut the rose flower obliquely with shears to ensure that the rose better absorbs water and nutrients, otherwise the original pruning part will affect the opening period of the flower.

Then, put the flowers in a vase with water, so that the water does not cover the flowers and leaves to prevent them from rotting. Add a piece of grated aspirin before filling the vase with water so that the freshness of the flowers will last for an additional 7 days.

Finally, change the water once every two days, wash the flower branches soaked in the water when changing the water, clean the vase to prevent fungus, and don't forget to put aspirin when changing the new water.

Every day, there are watering cans that spray a small amount of water on the flowers.

If you're going to keep it for a while, buy the unopened one when you buy it, making sure it blooms for a long time.
