How to grow potted roses?

Most of the roses are world-famous ornamental plants, born by the roadside, by the field or in the bushes in the hills, widely distributed in the cold temperate to subtropical regions of Asia, Europe, North Africa and North America, with a very high ornamental value. The cultivation history in our country is very long, which is very suitable for bonsai cultivation. Let's take a look at how to grow potted roses.

How do roses reproduce?

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. Roses can also be propagated by tissue culture, water culture, grafting, plantlet and so on.

How to transplant roses?

1. Potted soil configuration: in the preparation of potted roses, attention should be paid to drainage, ventilation and the collocation of various nutrients, the proportion of which is 5 parts of garden soil, 3 parts of rotten leaf soil: 2 parts of rice chaff ash, which is suitable for turning basin, pruning root and changing soil every year before and after wintering. The basin diameter should be increased year by year, and the mud pot is the best.

2. Transplanting time: the pot of potted rose is not limited by the season, as long as the root system of seedlings is suitable or with soil, it can be used in spring, summer and autumn. It is appropriate to plant large roses in the dormancy period after falling leaves in winter or before sprouting in early spring, otherwise the normal growth and development will be affected, the tree potential will be weakened and it will take a long time to rejuvenate. Rose seedlings on the pot is regardless of the time, as long as it is cultivated to survive, it can be put on the basin to prevent it from growing and weakening.

3, pot method: small rose seedlings pick up seedlings gently shake, so that the roots fully stretch, large seedlings do not need to do so, usually one pot, pot less can be a pot of two or three (later branching place may not be enough), large rose stem thick leaf green flowers, stamens, bright color.

Cultivation and management of rose

1. Watering: the watering of roses varies from season to season. Keep the soil moist and dry during winter dormancy. The branches grow before the beginning of spring, the branches and leaves grow, increase the amount of water appropriately, and irrigate once every morning and evening. Need to increase the amount of water in the growing season and flowering season, high temperature in summer, the amount of water evaporation increases, plants are in a weak semi-dormant state, the most avoid drying and dehydration, watering once every morning and evening to avoid sun exposure. When watering at high temperature, a small amount of water should seep out from the bottom of the basin each time, indicating that it has been watered thoroughly. Do not splash water on the leaves when watering to prevent diseases.

2. Fertilization: roses like fertilizer, and the base fertilizer is mainly slow-acting organic fertilizer, such as cow manure, chicken manure, bean cake, oil residue and so on. Adding liquid fertilizer and water every semimonthly can always keep the leaves thick, dark green and shiny. Before sprouting in early spring, thick liquid fertilizer can be applied once, no fertilizer should be applied at flowering stage, liquid fertilizer can be applied again after blooming in June, medium liquid fertilizer can be applied again when the fourth or fifth axillary bud is about to sprout in September, and rotten organic fertilizer can be applied to overwintering in December.

3. Pruning: comprehensive pruning must be carried out after the blooming of the first period of each season. It is generally appropriate to trim lightly, cut off the blooming residual flowers and thin, crossed and overlapping branches in time, leave stout and young branches only 3-6 cm from the base, leave lateral buds, trim into a natural happy shape, make the plant beautiful and prolong the flowering period. In addition, potted roses should choose varieties with short, multi-flowered and rich aroma.

4. Disease prevention: roses are easily infected with many diseases, and most of them are caused by fungi, such as powdery mildew, black spot, rust and so on. Usually maintenance should pay attention to pruning branches and leaves, conducive to ventilation and ventilation, before the occurrence of diseases and insect pests, can be sprayed liquid control, sterilization and disinfection. If diseases and insect pests have occurred, corresponding measures should be taken for treatment, so as not to affect the growth and flowering of roses.
