When should roses be cut back and how much
Roses grow vigorously and require correct pruning methods and appropriate pruning times. Rose pruning is usually done in spring and winter. Spring pruning promotes the growth of new branches and leaves, while winter pruning ensures sufficient nutrients for the branches and leaves.
Rose is a widely loved flower. It not only has a beautiful appearance and sweet fragrance, but also has rich cultural and historical significance. Roses can be used to express love, friendship, respect and appreciation, and can also be used to decorate homes and courtyards, adding color and fun to life. However, keeping rose bushes in good condition requires more than just watering and fertilizing; regular pruning is also required. Pruning rose branches can help the plants maintain healthy growth, prevent pests and diseases, increase flower yield and quality, and create a beautiful appearance. So, how to prune rose branches correctly? This article will introduce you to some basic principles and methods to help you become a qualified rose gardener.
First, we need to understand the structure of a rose branch. Rose branches are composed of main branches and side branches. The main branches are branches that grow directly from the roots, and side branches are branches that branch off from the main branches. On the main branches and side branches, there are some pinnate compound leaves, each compound leaf is composed of several leaflets. At the junction of the compound leaves and branches, there is a small dark protrusion called a bud eye. All new shoots sprout from the eye. Above the new shoots are the buds or flowers that have opened.
1. Rose tree pruning time
We need to master the timing of pruning rose branches. Generally speaking, pruning rose branches can be divided into four periods: winter pruning, spring pruning, summer pruning and autumn pruning. Each period has different purposes and methods.
– Winter pruning:
Winter is the dormant period for roses. Pruning during this period can reduce the plant’s demand for nutrients and water, prevent frost damage, and prepare for spring growth. Winter pruning should be done after the last flowering or before temperatures start to drop, usually between November and December. Winter pruning should be more thorough. All dry, diseased, pest-infested, crossed, repetitive, weak, and inward-growing branches should be cut off, and branches that are too long or too dense should be shortened or thinned appropriately. After winter pruning, the plant should retain only 3-5 main branches, and only 3-5 new shoots on each main branch.
-Spring pruning:
Spring is the peak growth period of roses. Pruning during this period can promote the germination of new buds, increase flower production, and improve plant shape. Spring pruning should be done when the temperature begins to rise or new shoots begin to sprout, usually between March and April. Spring pruning should be relatively light. You only need to cut off old branches, frostbitten branches, damaged branches and inward-growing branches that remain after winter pruning, and topping new buds on the main branches to promote the differentiation of side branches. After spring pruning, the plant should take on an open cup or umbrella shape with several new shoots on each branch.
– Summer pruning:
Summer is the flowering period of roses. Pruning during this period can extend the flowering period, improve flower quality, and prevent plant aging. Summer pruning should be done after each bloom, generally between May and September. Pruning should be more frequent in summer. All withered flowers and residual flowers should be cut off, and the two compound leaves under the flowers should also be cut off to facilitate the rapid growth of new shoots. When pruning in summer, pay attention to making diagonal cuts about 6 mm above the bud eye, making the cut at a 45-degree angle, and choosing a bud eye that faces the direction you want new branches to grow. After pruning in summer, the plants should maintain a moderate height and density, with several new buds or flowers on each branch.
– Autumn pruning:
Autumn is the period when roses are preparing for dormancy. Pruning during this period can reduce the plant’s consumption of nutrients and water, prevent the breeding of pests and diseases, and prepare for winter. Fall pruning should be done after the last flowering or before temperatures start to drop, usually between October and November. Autumn pruning should be relatively simple. You only need to cut off all residual flowers, residual leaves, dryness, diseases and insect pests, crossing, duplication, weak, and inward-growing branches, and shorten or thin out branches that are too long or dense. After pruning in the fall, the plant should take on a compact ball or cone shape, with only 1-2 new shoots remaining on each branch.
2. Pruning method
1. Pruning during the dormant period
Before roses go dormant, remove all remaining flowers, dead branches and leaves from the plants. The branches and leaves that are growing vigorously and affecting the density should be pruned in time, and the branches and leaves that are weak should also be pruned, which can promote the healthy growth of the plant and increase its ornamental value.
2. Pruning during the growth period
Spring is the growth period of roses. Prune branches and leaves that grow too fast in time, and clean up all leggy branches and leaves, diseased branches and leaves, and dry branches and leaves. Prune vigorously growing branches and leaves lightly to promote the germination of new branches and leaves. Accelerate flowering speed, increase flowering yield, and improve flowering quality.
3. Prune after flowering
After the roses bloom, the remaining flowers need to be pruned in time to promote later growth and flowering. Prune overlapping branches and leaves so that light can be evenly distributed to avoid disease.
4. Prune after disease
After roses are attacked by diseases and insect pests, diseased branches and leaves need to be pruned promptly and treated intensively to avoid expanding the infected area.
3. Pruning Technology
When pruning roses, be sure to avoid summer. Summer is hot and dry, which is not conducive to their recovery after pruning. Observe the growth of roses in each period, prune dead branches and leaves in time to promote the growth of new branches and leaves.
Finally, we should pay attention to the tools and methods for pruning rose branches. Pruning rose branches requires a pair of clean and sharp garden scissors and a pair of anti-thorn gardening gloves. You will also need a large bucket to transport the cut dead branches and leaves. Sterilize your scissors before pruning to prevent the spread of bacteria or fungi. When pruning, cut diagonally along the grain direction of the branches at a 45-degree angle, and cut approximately 6 mm above the bud eye. After pruning, clean up the site promptly, remove all dead branches and leaves, and water and fertilize the plants.
Through the above introduction, I believe you have mastered the principles and methods of how to prune rose branches correctly. If you follow these steps, you can make your rose bushes more beautiful and healthier, and enjoy the charm and pleasure they bring to you. if you still
