Can the branches of fresh-cut roses be cut and rooted?
Explaining to netizens whether the branches of fresh-cut roses can be cut and rooted, related topics about flower cultivation are very useful knowledge, recommended for collection!
Autumn and early spring are the most suitable times for cutting roses. During this period, the temperature is relatively low, rose cutting management is simple, the survival rate is high, and even新手 flower friends can easily root cuttings. At this time, some flower friends have whimsical thoughts: Can the discarded cut flower rose branches from flower shops be used for cutting? After all, there are very few shops selling cut rose seedlings. If the discarded rose branches from flower shops can be rooted, that would be great. So, is this method feasible?
Can the branches of fresh-cut roses be cut and rooted?
Of course, it is possible because the roses in the flowers are actually cut roses, and cut roses can naturally be rooted. However, some varieties may have a lower survival rate after cutting. When cutting, we recommend that you pay attention to the following details.
1. -- Choose branches with full buds --
When selecting branches, look for branches with relatively full buds. Branches that have been rubbed off on the buds cannot be used, and those with unclear buds are not recommended. If you buy fresh-cut flowers to take home, it is recommended to cut and root the branches first, and not to root them after the fresh-cut flowers have faded, as the branches will have consumed too much nutrients, making it difficult to root.
2. -- Soak in root-promoting agent --
Before cutting, the branches should be pruned, selecting the parts with full buds, making a 45-degree diagonal cut on the lower end and a flat cut on the upper end. A cutting can retain 1-2 buds, with a length of 6-8 cm.
After the cuttings are pruned, it is recommended to soak them in a solution of carbendazim and rooting powder. You can dissolve 1g of rooting powder and 1g of carbendazim in 800ml of water and then soak the branches in it for 20-30 minutes before taking them out to dry the surface moisture.
Soaking in rooting powder and carbendazim is mainly to promote early rooting and sterilize the branches, as well as to replenish the moisture of the branches. Since the branches of fresh-cut flowers are easily dehydrated and infected by germs during transportation, this treatment can greatly improve the survival rate.
3. -- Rooting in sterile soil --
Drying the branches is to allow carbendazim to form a protective film on the surface of the branches, making it less susceptible to germs. After the surface moisture of the branches has dried, you can proceed with the cutting. It is recommended to use sterile soil, which is soil without fertilizer, such as a mixture of 2 parts peat soil and 1 part perlite, or using pure perlite or pure vermiculite, and using the "wall crash 2.0" cutting method.
The difference between these two cutting methods is that the "wall crash 2.0" method is easier to root, but it often involves bare-root transplantation. Using peat soil to cut, after rooting, the transplantation survival rate is higher. If the temperature is relatively low, it is recommended to use peat soil directly, while if the temperature is still relatively high, using pure vermiculite is better.
4. -- Management after cutting --
The cutting process for cut rose branches is the same as for rose cuttings. The management after cutting is relatively simple. In autumn and winter or early spring, the light is gentle and can be directly exposed to the sun. If peat soil is used for cutting, the soil should be kept moist after cutting, and should not be short of water, otherwise the branches are prone to cutting failure, so water should be added immediately when the soil surface is dry. If pure vermiculite or pure perlite is used for cutting, the water tray should always have water.
In winter, it can be placed in an environment of about 5-10 degrees, with sufficient light, and the young plants that have rooted will grow roots quickly. If the temperature is below 5 degrees, the root growth will be slow, and if the temperature continues to be below minus 5 degrees, it will be a certain challenge for the young plants that have rooted. It is recommended to bring them indoors to overwinter.
The above is the complete introduction to whether the branches of fresh-cut roses can be cut and rooted. I hope it can be helpful to you. Don't forget to check out more flower cultivation experience and common knowledge!
