About these do you know? The topic of my hydrangea cutting method not alive, you find my flowers and plants, let's get to know together next.
Recently, everyone is talking about hydrangeas, so let's join in the fun today and talk about hydrangeas. About the cultivation of hydrangeas, a special introduction will be built later. Today, I will only briefly introduce the cutting method of hydrangeas.
There are many varieties of hydrangeas, and the flowers are very beautiful. Now many hydrangeas are almost finished blooming, which is the best time for us flower friends to exchange branches for cutting propagation.
If you still don't know how to cut hydrangeas, then the following content is recommended for you to read carefully.
Hydrangea cutting method - Hydrangea is one of the easier-to-cut species, but for beginners, it is still recommended to use a more reliable cutting method, which can ensure at least a 90% survival rate.
Branch selection
The best branches for hydrangea cutting are the semi-lignified branches of the current year. These can be combined with pruning after flowering. When selecting branches, try to choose strong ones, and when there are no options, weak branches should not be overlooked.
Branch pruning - The internodes of hydrangeas are usually long, so a pair of buds can be used as a cutting.
Trim 0.6-1 cm above the bud point flatly and 3-5 cm below the bud point diagonally at a 45-degree angle.
Now the important part comes, most of the leaves at the bud point should be trimmed, but not all, leaving a little for photosynthesis and nutrient production.
Cutting treatment
The trimmed branches are best soaked in potassium permanganate solution for disinfection. Dilute the potassium permanganate solution to a light purple color and then put the trimmed hydrangea cuttings into it for disinfection.
Hydrangea cutting soil preparation - While the hydrangea cuttings are being disinfected, let's prepare the soil for cutting.
Hydrangea cutting is easy to survive, and the soil for cutting is not very particular. However, since the temperature for cutting is already high, it is prone to infection by bacteria, so it is best to avoid soil with fertilizer or organic matter when preparing the soil.
You can use peat:perlite in a 1:1 ratio, or garden soil:river sand in a 1:1 ratio. This way, when cutting, one plant can be cut into a small pot, and it can be transplanted directly with soil after roots grow, resulting in a higher survival rate.
PS: If you are a beginner with no experience, it is recommended to use pure vermiculite or pure perlite. A size of 3-8mm is most suitable.
Cutting method
The prepared potting soil should be thoroughly watered with potassium permanganate solution for comprehensive disinfection.
When cutting, to make the hydrangea roots grow faster, you can use root powder or root solution, which can be omitted if not available.
If using a root solution, you can first take the hydrangea cuttings out of the potassium permanganate solution and drain them. After the branches are slightly dry, dip the bottom of the cutting in the root solution for 2-3 seconds before inserting it into the soil.
When using root powder, you can directly dip the cutting into the root powder after taking it out of the potassium permanganate solution and then insert it.
PS: Cutting depth
Previously, when sharing cutting methods, many flower friends asked about the depth of cutting.
Usually, the cutting depth is 2-3 cm. For hydrangea cutting, you can use the bud point as a reference, keeping the bud point on the soil surface.
Post-cutting management
After cutting, water the plant again to make the soil adhere closely to the branches. Then place the pot with the cuttings in a bright area with scattered light and maintain ventilation.
Caution: Try to avoid placing it in a drafty area as strong wind can cause water loss, making the branches dehydrated. Also, avoid direct sunlight, as it can easily cause the branches to dehydrate. Weak morning and evening sunlight is acceptable, but avoid strong sunlight.
Regularly spray water if possible, or at least keep the potting soil moist, and water promptly when the surface of the soil dries.
If cutting with pure vermiculite or pure perlite, it's better to water more rather than less. Daily watering is fine. You can also place a water saucer under the pot to keep it moist.
Tips
Hydrangea cutting grows buds before roots, so for those who are impatient, be careful not to pull out the plant when you see the buds, as this is often when the roots are just starting to grow or are very weak. Controlling your hands is important.
It's completely fine to transplant the hydrangea when the roots grow out of the bottom of the pot. Cutting requires patience, and if you don't have this patience, you might as well buy a potted plant.
