Rose Pruning After Spring Blooming
An article filled with practical knowledge, introducing the topic of pruning roses after spring blooming. Here is a comprehensive introduction.
Rose Pruning After Spring Blooming
During the Labor Day holiday is when roses are in full bloom, looking their best, which also signifies the end. After the roses fade, timely pruning is necessary to prevent seed formation, which would waste a lot of nutrients and affect the blooming of the next batch of flowers.
Yesterday, while guiding students in the Flower Care Camp, I noticed an issue regarding rose pruning. I believe this is an error that most rose enthusiasts might make. Today, I will talk about a few points to note when pruning roses after blooming.
Common Rose Pruning Mistakes
Novice rose enthusiasts often make the following three mistakes when pruning roses.
1. Not Pruning the Withered Flowers
Many novice enthusiasts don't know that they need to prune the roses after they fade, often leaving the withered flowers on the branches. Some rose varieties that don't produce seeds will wither on their own, while some seed-producing varieties tend to grow fruit, consuming a lot of nutrients.
In fact, many experienced enthusiasts often overlook the pruning of roses, perhaps because they think the roses don't look good in summer and neglect management, or they might be too busy. Not pruning the roses after blooming can lead to poor plant shape, causing them to grow taller without a proper shape.
2. Pruning One Branch After Each Withered Flower
Roses often don't bloom all the buds at once, with some opening first and some later.
The flowers that open first will also fade first. Many enthusiasts, upon seeing the roses fade, immediately prune them. If a branch has a withered flower, they prune the branch right away, as shown in the picture above.
This pruning method is not incorrect, but it's the reason why your roses only bloom one or two flowers at a time. Roses bloom on new branches, and after a branch is pruned, the bud points start to sprout. The first pruned ones sprout first and naturally bloom first, resulting in your potted roses blooming one or two flowers at a time instead of all together.
The correct approach is to cut off the withered flowers directly without pruning any branches. Just trim the withered flowers and wait until all have faded before pruning the branches uniformly.
3. Only Pruning Withered Flowers, Not Branches
Many enthusiasts simply prune the withered flowers, cutting one after each fades, but don't prune the branches. You can see that the flower stems are still on the branches.
This pruning method is the same as not pruning for varieties that don't produce seeds, as it only prevents seed formation but doesn't control the plant shape or stimulate new bud growth.
After rose blooming, prune some branches to control the shape, generally cutting off 1/3-1/2 of the flowering branches, depending on their length.
If you find it difficult to judge this pruning amount, the simplest method is to find the first leaf with five small leaves below the flower and prune with this leaf. However, this method is not suitable for shrub roses as it's hard to achieve a good shape.
The methods for adjusting the shape of rose plants and controlling blooming periods are detailed in the book "How to Grow roses from Scratch." You can use the methods introduced in the book to achieve this.
4. Pruning Branches at Different Heights
To control the shape of roses, you need to pay attention to the bud points when pruning, trying to keep them at the same height.
When everyone is at the same starting line, the new buds will naturally be at a similar height. If some branches are left high and others low, the plant's apical dominance will cause the higher branches to sprout first, receiving more nutrients and growing more vigorously than the shorter branches. This makes it impossible to control the shape evenly.
Therefore, when pruning, try to keep the bud points at the same height. Strong branches can be slightly lower than thin ones because the new buds on strong branches are usually also stronger. If the starting point is slightly lower, the final blooming will be more uniform in height.
