How to plant rose seeds?

Planting time:

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 m in length and 1 m in width and 0.6-0.8 m in depth, or dig planting ditches with depth and width of 0.6-0.8 m. The plant was applied with organic fertilizer and superphosphate, mixed with soil and concentrated at the depth of 0.2-0.5m. After planting, the plant was irrigated in time.

Seed propagation methods:

Rose seeds have dormancy period, direct seedling will not emerge until a year later, so seedlings need to be treated to break the dormancy period first.

Treatment method: commonly used stratification to promote germination, soak the seeds in water for 2 days, remove and mix them with 3 times wet sand, appropriate to hold the sand clumps into finger seams and soak them without water, put the mixed sand seeds into containers and often keep them moist. This treatment method is often carried out in winter. Before sowing in spring, the seeds are screened for drying and sprinkled with water, and the seeds can be sowed when half of the cracks are made.

Other cultivation methods:

Rose strong, regardless of soil, cold-resistant, drought-resistant, the land is not divided into north and south, home all over the world. Cuttings are generally used for propagation, and the survival rate is more than 90% as long as it is shaded and kept moist. The trailing branches can also be pressed into the soil during the growing period, and can be cut off and planted again after taking root. Sometimes grafting or sowing is also used.

Watering and fertilizing

The rose is happy and moist and afraid of waterlogging. From sprouting to blooming, the water can be watered more appropriately, with the soil moist but not waterlogged as the degree, not too much watering after flowering, the soil should be dry and wet, and attention should be paid to drainage and waterlogging prevention in the rainy season.

Rose likes fertilizer and is tolerant to barren. Liquid fertilizer dominated by nitrogen can be applied once or twice in March to promote the growth of branches and leaves. In April and May, fertilizer mainly based on phosphorus and potassium can be applied three times in April and May to promote its poly-pregnant buds to blossom more. After anthesis, it can no longer be fertilized after applying compound fertilizer again. Rose positive flowers, like warmth, but also hardy, North China and its south, can survive the winter outdoors safely.

Pruning

The rose has strong sprouting power and luxuriant growth. if it is not pruned in time, it is prone to diseases and insect pests under the conditions of muggy, humid, lack of light and poor ventilation, so a pruning should be carried out after flowering. When pruning, you can choose the sturdy branches that are semi-lignified in the same year, place them in the semi-shade, transplant them in the following spring after survival, or cut off the roots of the sprouting daughter plants before sprouting in early spring.

Pest control

Under the conditions of rainy, humid, poor ventilation and poor sunshine, Rosa is easy to suffer from powdery mildew. Once found, the diseased branches should be cut off and destroyed to avoid infection, and low concentration of stone sulfur mixture or Bordeaux solution and topzine solution should be sprayed to prevent the spread of the disease.
