Pruning the rose is divided into two periods, each of which has to be fine.

Rose, needless to emphasize many times, flower friends all know that pruning is an important thing. However, after talking about pruning many times, many flower lovers still don't know how to deal with it. In fact, pruning the rose, divided into two periods, each pruning is done "fine", the rose can bloom the four seasons.

The two periods of pruning of Chinese rose are divided into growing pruning and dormant pruning. Below, some pruning methods and techniques of each period are introduced in detail.

1. Pruning during the growing period

The pruning of rose during the growing period includes wiping buds, picking buds, picking hearts, cutting shoots and removing residual flowers, etc., and the total amount of pruning during the growing period should be light.

(1) sprouting: during the growing period of rose, the excess buds are erased according to the needs of modeling to reduce the consumption of nutrients. A main branch usually leaves only 2 or 3 full buds.

(2) coring and pruning: when the new branches grow to a certain length, if it is necessary to thicken the branches or promote the axillary buds to sprout into lateral branches, the main branches are coring or pruning, that is, the young tips that are not lignified at the top of the branches are removed for coring, and if the parts that need to be trimmed have been Lignified, pruning is used to cut off the top part of the branches.

(3) Bud picking: for the hybrid aromatic rose with single branch flowering, the lateral buds can be removed, only one main bud in the middle of the flower branch can be removed, and the nutrients can be concentrated to cultivate large flowers. For multi-flower varieties and strong flower varieties, too many poorly developed small buds can be removed, strong buds can be left, florescence can be concentrated, flowers are large, flowers are uniform and miniature rose does not pick buds. The buds formed by newly planted young rose plants for the first time should be removed and the nutrients should first be concentrated to grow a good tree shape.

(4) removing residual flowers

The residual flowers should be cut off immediately after each rose flower fade. Cut the 0.5cm at the base of the second compound leaf under the remnant flower so that the lower axillary bud branches and blossoms again.

No matter which form of pruning is used, after the pruning is completed, it is necessary to replenish nutrients to the rose in time and use topdressing to promote the growth and development of the rose. It is generally recommended that flower friends use organic liquid fertilizer for rose, the ratio of fertilizer to water is 1: 500, once a week, just irrigate the root directly.

2. Dormant pruning

When the rose is pruned during the pruning period, the nutrient loss is small, and the big branches can be pruned according to the modeling requirements, and cut off the disease and insect branches, withered branches, cross branches, overlapping branches, drooping branches, over-dense branches, weak branches, sprouting branches at the base, sprouting branches below the shaping belt on the stem, etc.

Then according to the characteristics of the variety, according to the needs of the shape is divided into strong, medium, weak and other different degrees of pruning. The natural laissez-faire trees and the old and weak trees are renewed, rejuvenated and pruned.

(1) strong pruning: strong pruning is generally carried out for rose plants with weak growth and potted rose varieties with large flowers, that is, 2% of the whole plant is cut off and only 2% of 4 main branches are retained.

(2) medium pruning: this method is often used for varieties with moderate growth, uniform tree-shaped branches and easy striping. Cut off about 1 stroke 2 of the whole tree.

(3) weak pruning: weak pruning is carried out for some plants with strong growth potential and cultivars of Rosa chinensis, which is cut off from the whole plant.

In addition, when the new shoot of potted annual rose seedlings grew above 30cm, it was cut off about 2pm 3, which was less than that of 30cm. Plants that are too small are not pruned for the time being and are allowed to grow naturally. The renewal of old and weak plants can be completely cut off from the base, and after the root neck grows out of new branches, it will be pruned according to the requirements of modeling.

In short, if you want to make the flowers of the four seasons of the rose fragrant and gorgeous, you must do a good job in regulating light, heat, water and gas according to the ecological habits of each variety, pruning, fertilizing the rose in time, so that it can sprout and grow better.
