How to prune roses after blooming
Yesterday, I posted a video about pruning roses after blooming on my social circle, and then saw many flower friends' comments asking about pruning. Today, I will introduce the specific methods for pruning roses after blooming.
Pruning and Precautions After Rose Blooms
Pruning roses after blooming is simpler compared to winter pruning, with less stringent requirements. As long as they are not pruned completely bald, it is fine. However, if you want them to grow vigorously and continue to bloom, there are still many considerations in pruning.
1. Pruning Timing
Many flower friends are still unclear about when to prune roses in spring. I've encountered many who prune as soon as the roses fully bloom, but in fact, most rose varieties can continue blooming for 4-7 days after full bloom in spring.
Therefore, pruning immediately after full bloom is too early, shortening the time for appreciating the flowers. However, pruning early also has its benefits, such as saving a lot of nutrients in the rose plant, which is beneficial for subsequent growth and blooming.
If you like to arrange flowers in vases, it is better to cut the flowers early, preferably when they are half open. Many rose varieties look most beautiful when half open, and placing them in a vase with flower preservatives can also keep them fresh for a long time.
Most of the time, we prune when the color of the rose fades or the petals fall off.
2. Pruning Preparation
Before pruning roses after blooming, we need to control the watering appropriately and avoid pruning right after watering or fertilizing. The pruning time should be chosen on a sunny day, preferably at noon when the temperature is high, as the wounds will dry quickly after pruning. Of course, pruning in the morning or evening is also fine.
Many flower friends are concerned about whether to disinfect the pruning shears. In fact, it's not that complicated. My shears are already rusty, and I use them without hesitation, so I've always felt that there is no need to pay too much attention to disinfection, as the chance of infection is negligible.
3. Pruning Method
Pruning roses after blooming can be divided into two situations. Often, some flowers on a rose plant will wither first. If it's a multi-head variety, it's simple, just cut off the spent flowers. But what if there's only one flower on a branch?
Should we cut the branch then?
If the branch is cut back, the new buds on this branch will sprout earlier than other branches, resulting in uneven blooming for the next batch of flowers. Therefore, for single-head varieties, just cut off the spent flowers like multi-head varieties, without cutting back the branch.
Wait until more than 90% of the flowers have withered before trimming the branches uniformly. The general pruning amplitude is 1/2 of the length of the flowering branch. If the branch is longer, you can prune 2/3 of the flowering branch, and for micro roses or short flowering branches, just cut 1/3.
For specific pruning methods for micro roses and climbing roses, you can refer to the detailed introduction in the book "How to Grow Roses from Scratch."
When pruning, try to make the retained buds more uniform in height, with stronger branches slightly lower. The method of retaining buds can be adjusted according to the plant shape needed. For varieties that naturally grow more vigorously, more inward buds can be retained to make the new branches converge.
One thing to note is that unopened flower buds should also be cut off. If there are suckers that have grown tall, they need to be topped at the same time. If the suckers are not tall enough for topping, you can wait another two days before topping.
In addition to pruning flowering branches, pay attention to pruning internal dense blind branches and weak branches, and remove old leaves near the bottom. These old leaves are prone to spider mite infections, and removing them can increase plant ventilation and reduce the probability of infection.
The above pruning method applies to relatively healthy rose plants. If the rose plant is weak and has few leaves, it is recommended to only remove the flowers and flower buds without cutting back the branches.
