Green plants and flowers: an introduction to the artificial cultivation and propagation methods of roses

Rose, also known as wild rose, is a plant of upright, climbing or spreading deciduous shrubs, mainly distributed in the temperate, subtropical and tropical mountainous regions of the Northern Hemisphere. Want to know how to cultivate roses artificially? This is an introduction to the artificial cultivation and propagation of roses.

Artificial cultivation of roses

The adaptability is quite broad. Apart from China's winter and cold winters, the vast southern regions are also suitable for planting. The longer the plant grows, the more flowers it blooms, and the more nutrients it needs. Every winter, fertilizer needs to be applied once a year to keep the buds and flower buds thriving and the scenery beautiful. For the cultivation of potted flowers, more attention should be paid to pruning and shaping. Cut flowers have a large number of blooms, and during the flowering season fertilizer needs to be applied 1-2 times a week; attention should be paid to cultivating flowering mother branches and cutting off flower buds on weak branches.

Wild roses have few pests and diseases; artificially cultivated ones suffer from pests such as sawflies, scale insects, aphids, and diseases such as scorch, canker and black spot. In addition to using liquid sprays, the landscape should be used together with other flowers, plants and trees, and too many should not be planted.

Every winter, old branches and dense branches are often pruned to maintain light and ventilation, thereby reducing pests and diseases. Pruning is an indispensable and important process in rose landscaping; poor pruning leaves a pile of thorns, uneven, not only pests and diseases but also ugly.

How to propagate roses

Seeds can be used for seedlings, but in production, young branches are used to cut seedlings and they are easy to survive. Valuable varieties are harder to cut and can be propagated by layering or grafting; asexually propagated seedlings can bloom in the same year.

For seedlings used for potted plants, old branches of excellent varieties should be selected and seedlings raised by the layering method, and the main branches should be pruned for artificial dwarfing. For seedlings used for cut flowers, it is necessary to select seedlings that can form flowering mother branches and large flower colors.
