When can hydrangeas be propagated by cuttings?
About these, do you know? When can hydrangeas be propagated by cuttings and knowledge about the cultivation techniques of green plants and flowers. Let's learn about it together next.
Introduction: Speaking of hydrangeas, I believe many rural friends are familiar with them, right? They can often be seen by the roadside and in grass丛, usually in purple-blue color. So, when are hydrangeas propagated by cuttings? How to propagate them? The editor will tell you about it below.
Speaking of hydrangeas, I believe many rural friends are familiar with them. They can often be seen by the roadside and in grass丛, usually in purple-blue color. So, when are hydrangeas propagated by cuttings? How to propagate them? The editor will tell you about it below.
I. When can hydrangeas be propagated by cuttings?
Hydrangeas can be propagated by cuttings from April to July in spring, as the temperature during this period is very suitable for root growth and is also in the period of growth and germination, which is conducive to the rapid growth of roots. Apart from spring, you can also choose to propagate in September to October in autumn, with a good rooting rate. The other two seasons can also be propagated, but the temperature should be well controlled, with cooling in summer and insulation measures in winter.
II. How to propagate hydrangeas by cuttings?
1. Pruning branches
It is best to propagate hydrangeas in spring, preferably in the evening. It should be avoided to prune when the temperature is too high or the sun is too strong, as it can easily cause damage to the branches and leaves of the hydrangeas. Select branches that have not yet formed new buds, cut off a section of healthy branches about 9-12 centimeters long, and you can cut off several sections. It is best to use a sharp, alcohol-wiped pair of scissors to avoid fungal diseases and prevent mold infection.
2. Removing extra leaves
After cutting the branches to an appropriate length, some leaves should be cut off. The bottom leaves should be completely removed, leaving about 3-4 leaves on the top. It is necessary to remove the bottom leaves, as it can affect root growth and easily cause fungal diseases. When pruning leaves, be careful not to damage the branches and prune from the bottom of the petiole.
3. Paying attention to leaf buds
When pruning the bottom leaves, we will see some small block-like structures at the cut end of the petiole, which are the leaf buds. They will grow into branches later. Do not damage these leaf buds when pruning. If accidentally injured, discard the branch and do not attempt to propagate with it, as it is easily infected with root rot disease.
4. Pruning the top leaves
Since hydrangea leaves are very large, cut off 2/3 of the top leaves to reduce water consumption of the branches. Only by doing this can promote faster root growth and new leaves in hydrangea branches, usually taking about a month to grow new leaves.
5. Promoting root growth
Apply some rooting powder to the bottom of the branch to promote root growth and prevent fungal diseases. If there is a rooting solution, soak it directly for five minutes before taking it out.
6. Soil propagation
Finally, propagate the hydrangea branches in loose, well-draining soil and plant them stably in the soil. However, be careful not to choose a container that is too large. You can select a pot 8-12 centimeters in size with good drainage holes at the bottom to prevent excessive soil moisture and root rot. Use loose, well-draining sandy soil, preferably new soil, and a mix of peat soil and sand.
7. Post-propagation care
After propagating the hydrangea branches, keep the soil slightly moist but not too wet, and avoid waterlogging. The placement should be in a location with appropriate scattered light and ventilation. Avoid direct sunlight and can be placed in a place with a bit of scattered light in the morning or evening.
Well, that's all the content I wanted to share with you today. Hydrangeas are usually propagated from April to July, and I have explained the specific methods to you. I hope this article can help you.
Are the above contents about when hydrangeas can be propagated by cuttings and understanding the cultivation techniques of hydrangeas clear to green plant enthusiasts?
