Recently, many rose enthusiasts have been asking whether to prune roses after they finish blooming and how to do it? Today, let's talk about the methods for pruning roses after bloom.
Methods for Pruning Roses After Bloom
Those who cultivate roses know that roses bloom once a month almost, and need proper pruning after each bloom to promote new branches and continue flowering. However, the methods for pruning roses after bloom vary in different seasons.
1. -- Spring Pruning After Bloom --
In spring, roses bloom neatly with large and standard flowers. After the first bloom in spring, the first pruning should be done. Generally, the blooming branches are pruned to half their length to dwarf the rose plant and maintain a good shape. After pruning, the new branches of the roses will be sturdier, and the quality of the flowers in the next bloom will also be better.
2. -- Summer Pruning After Bloom --
When the second bloom of roses in spring ends, it's already summer. Pruning roses in summer falls into several situations, and the pruning methods are directly related to our management.
For example, if the roses are well managed, grow robustly with many leaves, even after the second bloom in spring, the pruning can still be the same as the first time, cutting off half of the blooming branches.
But if the management is not in place, and the roses are infected with black spot disease, causing a lot of leaves to fall off, then the post-bloom pruning should only remove the残花 (withered flowers) to retain the leaves. If the rose plant still has many healthy leaves, the pruning can be done with 1-2 leaves remaining.
In addition to black spot disease, red spider mites can also cause weak growth or even no growth in roses. In such cases, the first step is to control the red spider mites, and the pruning should mainly focus on removing残花 (withered flowers), and flower buds should also be removed.
This kind of pruning is not only done after the second bloom in spring but also throughout the summer. Healthy plants are pruned normally and lightly, while those in poor condition are pruned to retain leaves. If there is no intention to let them bloom in summer, flower buds can be removed to save nutrients for the autumn bloom.
3. -- Autumn Pruning After Bloom --
Roses usually undergo a shaping prune when entering autumn. The methods for shaping pruning have been introduced in previous articles, or you can refer to the book "How to Grow roses from Scratch to Bloom," and I won't go into too much detail here.
The pruning time for roses in autumn is usually from the end of August to early September, with the north slightly earlier and the south slightly later. After the autumn pruning, roses generally bloom around the National Day. So the question arises, how should you prune the roses now after they finish blooming?
My personal view is that if you are not in the warm southern regions, now you should only cut off the残花 (withered flowers) when pruning roses, without cutting back the branches or leaves. But if you are in the warm southern regions, you can still treat it as a light prune.
Why is there such a difference? The main reason is temperature. The time it takes for roses to bloom after pruning is greatly affected by temperature. In summer, it takes about 35 days for roses to bloom after pruning, but now that the temperature is decreasing, it may take about 60 days from pruning to blooming, and by then, the temperature might be very low, and the rose buds may not be able to open. Therefore, to ensure that the second autumn bloom can open steadily, I suggest that after the first autumn bloom, you only cut off the残花 (withered flowers), so that new buds will quickly sprout from the top and bloom again.
If the winter in your area is relatively warm and you don't have to worry about the buds not opening in time, you can prune normally and lightly. If you are in the northern regions and the temperature is already relatively low, and there are still flower buds and残花 (withered flowers) on the branches, you can wait and let them enter dormancy naturally because pruning will stimulate the flow of nutrients and may cause new buds to grow, wasting nutrients.
The above introduction of pruning methods for roses after bloom and the comprehensive explanation of how to prune roses after bloom should be able to solve your problems with green plants.
