How to raise roses

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 more difficult to cut, and can be propagated by striping or grafting. Seedlings of asexual reproduction can blossom in the same year and can be used as seedlings of potted flowers. Older branches of fine varieties should be selected, seedlings should be raised by striping method, and attention should be paid to pruning main buds, artificial dwarfing, and seedlings used as cut flowers, varieties that can form mother branches of flowers and large and colorful flowers should be selected to raise seedlings.

Culture method of rose flower

1. Propagation: ramet, cuttage and striping propagation are commonly used, which can be carried out in spring, early summer and early autumn. It can also be sown in autumn or in spring after sand storage, and germinate 1-2 months after sowing.

2. Cultivation: ground planting, ditch should be opened before planting 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. 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 2-3 times to promote the unflowered branches to blossom in the following year.

3. Moisture: the rose is happy to moisten and is afraid of waterlogging. From budding 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.

4. Topdressing: rose flowers like fertilizer and tolerate barren. Liquid fertilizer dominated by nitrogen can be applied once or twice in March to promote the growth of branches and leaves, and fertilizers dominated by phosphorus and potassium should be applied twice to three times in April and May to promote more flowering of its poly-pregnant buds. After anthesis, there can be no more fertilization. Rose positive flowers, it likes warmth, but also hardy, North China and its south, can be safe in the outdoor winter.

5. Post-bud management: the rose flower has strong sprouting power and luxuriant growth. If it is not pruned in time, diseases and insect pests are easy to occur under the conditions of muggy, humid, insufficient light and poor ventilation, so a pruning should be carried out after flowering.

Matters needing attention in rose culture

1. The rose flower has a strong ability to sprout, so it must be pruned in time and pruned in time after flowering to ensure the light and ventilation of the branches.

2. The cultivation and management of rose can be extensive, and the requirements for soil, fertilizer and water are not high, so it is best to cultivate it with loose and slightly acidic soil with organic matter.

3. After the beginning of winter, cut off the disease, insect and dead branches and retain a certain number of thick and strong branches in order to increase the number of flowers.

4. in order to reduce diseases and insect pests, it is best to do a good job of prevention and control in the growing season between spring and summer.

How to prune roses

The main purpose of pruning rose flowers in summer is to cut off the sprouting branches of grafted rootstocks, cut off residual flowers with leaves and remove excess buds after flowering, so as to reduce nutrient consumption and create good conditions for next flowering. In order to make the plant shape beautiful, you can cut off 3 or half of the long branch, 1 inch of the middle branch and 1 cm above the leaf. If the pruning is too light, the rose plant will grow taller and taller, the branches will be longer and thinner, and the flowers will be smaller and smaller.

Winter pruning depends on the variety and cultivation purpose, leaving branches during pruning, and paying attention to the overall shape of the rose plant. Large flower varieties should leave 4-6 branches, grow strong buds on one side with a length of 30cm to 45cm, cut off their upper branches, and vine or vine varieties mainly remove old techniques, cut off weak branches, diseased branches and cultivate the trunk.

In addition to nursing, pruning is also an important key factor for roses to grow well, because pruning can inhibit its fast-growing branches from absorbing its own nutrients, and it can also cut off its diseased branches so as not to cause overall harm. but to remind you that the pruning methods of summer and winter are different, we can refer to the above methods.
