Is there no root formation in cutting propagation?
This article provides you with detailed knowledge about the lack of root formation in cutting propagation for green plants and flowers, which will surely help you. Let's learn about it together!
The most widely used propagation method in the reproduction of flowers is cutting.
Cutting is a propagation method that utilizes the totipotency of plant cells to propagate using branches, leaves, or buds.
Home flower cultivation often adopts branch cutting propagation, but many flower enthusiasts encounter the problem of no root formation during practical operations.
The speed of root formation in cuttings is not only related to the environment but also greatly related to the conditions of the branches themselves.
Generally speaking, if the cutting contains more growth hormones, it will root faster in the same environment. A higher content of growth hormones also indirectly equals more nutrient storage.
Therefore, when cutting, we can intentionally change some influencing factors and make some minor adjustments to help the branches root quickly.
Tips to promote rapid root formation in cuttings
1. Girdling treatment
This has been introduced in detail when discussing the aerial layering method.
Girdling has many benefits and is also used in woody flowers and fruit trees.
7-10 days before cutting, you can first perform girdling on the branches to be cut for propagation, and then wrap them with plastic tape.
Pay attention to the width of the girdling, which should not be too large. Wrapping is done to maintain moisture; otherwise, if the wound is too large, it can easily dry out and lead to the death of the branch.
About 7-10 days after girdling treatment, the healing tissue has basically started to grow, and at this time, the branches can be cut for propagation, which can significantly increase the speed of root formation.
2. Heel cutting
The more nutrients stored in the cutting, the easier it is to propagate. For some difficult-to-propagate varieties, we can use heel cutting.
What is a heel?
Simply put, a heel is the position of the fork, where there are often many hidden bud points and a lot of nutrients stored.
Cuttings with heels are relatively easier to survive and root faster.
3. Using root stimulators
As mentioned above, the amount of growth hormones in the cutting directly determines the rooting speed and success rate of cutting propagation.
