What to do about the bleeding in Chinese roses?
Recently, have the rose enthusiasts among us been worried about pruning issues? It turns out that those who pruned early have encountered the problem of bleeding. A few days ago, I also pruned and repotted my Chinese roses, and one of the small climbing roses showed signs of bleeding. So why does bleeding occur? Let's analyze the reasons that cause Chinese roses to bleed, hoping to help those preparing to prune.
Reasons for the bleeding of Chinese roses
First of all, let's understand what is meant by the bleeding of Chinese roses? Normally, when we prune Chinese roses in winter, the cut ends will quickly dry quickly. However, if there is bleeding, the cut ends will continue to seep fluid. We call the phenomenon of the wound continuing to bleed after pruning Chinese roses.
The main reasons for the bleeding of Chinese roses are as follows:
1. Pruning heavily before the rose has entered dormancy
We can only prune heavily in winter because Chinese roses enter dormancy in the cold winter, with sap flowing back to the roots. At this time, pruning rarely results in nutrient loss and can make the basal buds plumper.
If we prune prematurely before the rose has entered dormancy, the sap is still flowing upward normally, and heavy pruning can easily cause bleeding due to the high pressure of sap being transported upward from the roots.
For example, if we cut our finger and press it for a while, it can stop bleeding, but if an artery is cut, it's hard to stop the bleeding because of the different pressure.
Especially for some miniature roses, which grow vigorously and are sensitive to temperature, pruning in winter can easily cause bleeding.
2. The potting soil is too moist
In addition to heavy pruning without pruning, excessive moisture in the potting soil is also one of the main reasons for bleeding.
If the Chinese rose has been watered or rained through before pruning, the roots will absorb a large amount of water from the soil, and pruning at this time can easily cause bleeding in the Chinese rose.
Prevention methods for the bleeding of Chinese roses
To prevent bleeding after pruning Chinese roses, we can perform two operations before pruning to reduce the probability of bleeding.
1. Remove leaves early to induce dormancy
To prevent bleeding during pruning, for some roses that have not yet entered dormancy, especially Chinese roses, you can remove all the leaves one week in advance to force the rose into dormancy.
After the sap flows back to the roots, pruning can greatly reduce the occurrence of bleeding.
2. Control water early to keep the potting soil slightly dry
Just forcing dormancy is not enough. It is most important to control watering before pruning, keeping the potting soil relatively dry. This way, there won't be too much moisture in the potting soil, naturally reducing the occurrence of bleeding.
Methods to deal with bleeding
When Chinese roses show signs of bleeding, we can use candle wax to seal the pruning cuts, or hot melt glue can also be used to seal the wound.
If not available, you can try burning the pruning cut with a lighter. This can not only stop the bleeding but also kill germs, preventing wound infection. Of course, the best approach is to prepare preventive measures before pruning.
