How to prune roses in winter
Share some related experience about roses and how to prune them in winter. Next, the editor will introduce how to prune roses in winter.
Many rose lovers need to understand how to prune roses in winter, because roses bloom on new branches, and the branches become finer the higher they grow, the farther away from the roots, the longer the distance for water and fertilizer transportation, and the smaller the flowers, which are not standard in shape. Therefore, we need to prune to achieve the goal of abundant flowering.
1. Pruning shrub roses or mini roses in winter
In dormant areas, through winter pruning, it is basically done at the first level of branches, which greatly shortens the distance for water and fertilizer transportation. Remove weak branches, intersecting branches, overlapping branches, inward branches, and branches that do not meet the plant shape requirements. Try to cut just above the full buds on the outer side. Clean up the fallen leaves on the surface of the potting soil. When the temperature is low, the transpiration is weak, and watering thoroughly can almost last the whole winter, unless the entire potting soil is dry, in which case there is no need to water. If repotting at this time, organic fertilizer or slow-release fertilizer can be placed in the medium as a base fertilizer. For example, 10g of slow-release fertilizer can be used for one liter of medium, and more organic fertilizer can be used. In the spring, when the plants start to germinate, ordinary compound fertilizer can be applied with watering.
2. Pruning climbing roses in winter
The habit of new branches blooming still applies. Therefore, it is necessary to break the apical dominance, otherwise only a few buds at the top of the branches will germinate into branches, resulting in sparse flowers and failing to show the grandeur of the climber. For winter pruning of climbers, cut off about 10 to 20 centimeters from the top of the main branches, retain three or so buds on the flowering lateral branches, remove the very thin, short branches at the base, and spread the branches near the wall or fence in a peacock-style display, allowing the branches to be as倾斜 or horizontal as possible. For the支柱, wrap them spirally around it, tying and wrapping as you go. Cut off any branches that exceed the支柱 range. For arches, tie the branches along the shape of the arch, or wrap them spirally around it, or let the thicker branches follow the shape of the arch and the finer ones wrap around. Similarly, cut off any branches that exceed the arch range. First pull the longer branches horizontally, then fill in the gaps with shorter ones. For large-flowered varieties, the distance between branches can be the width of a palm, and for medium-flowered varieties, the distance of a fist is enough.
3. After winter pruning, it is recommended to spray a concentrated solution of lime sulfur once, dilute 45% concentration with 30 to 40 times water, and spray on the upper and lower parts of the branches, the surface of the potting soil, and the ground. Dispose of the pruned branches and leaves at a distance, which is called cleaning the garden, and can reduce many diseases and pests in the spring.
4. In non-dormant areas such as Guangdong, it is also recommended to cut back the plants by one-third or half at the coldest time, preferably to the first or second level of branches, to make the emerging branches thicker and stronger. Since they do not go dormant, they will continue to grow, so make sure to follow up with fertilization and watering after pruning.
5. For potted plants, a good base fertilizer is essential for strong growth. After the base fertilizer is sufficient, ordinary compound fertilizer can be used for top dressing during the growth stage, at a ratio of 0.1% to 0.3%. For strong plants with many leaves, 0.3% is fine, while for weaker plants, 0.1% is enough, mainly considering the root strength's ability to absorb water and fertilizer. For top dressing, either mix with water or shallowly bury it on the surface of the potting soil, which is better than directly spreading it on the potting soil.
