How to propagate hydrangeas
Here is an explanation about how to propagate hydrangeas, including the timing and methods of propagation, which is very useful knowledge for green plants and flowers. It's recommended to save this information for future reference!
Hydrangeas are generally propagated in spring and autumn. Propagation in summer is also possible, but it should be done during the plum rain season in June and July, and the temperature should be controlled between 13 to 18 degrees Celsius. When propagating, the cuttings should be selected from healthy, disease-free, apical branches with nodes, and the growing medium should have good drainage and be loose and breathable. After planting, place the cuttings in a well-ventilated area with scattered light, control the temperature, keep the soil moist, and wait for about 15 days for roots to form.
1. Propagation Timing
Hydrangeas prefer a warm, humid, and semi-shaded environment. They grow vigorously in spring and autumn. Propagation is usually done in these seasons to ensure the survival and rooting of the cuttings. It can also be done in summer, but it should be during the plum rain season in June and July, with the temperature controlled between 13 to 18 degrees Celsius.
2. Cutting Selection
High-quality cuttings have a higher survival rate, faster rooting, and more robust growth after potting. When propagating hydrangeas, the cuttings should be selected from healthy, disease-free, apical branches with nodes, cut to about 20 centimeters, retaining the upper leaves, removing the lower leaves, and making a diagonal cut at the bottom.
3. Medium Preparation
The propagation medium should have good drainage and be loose and breathable to ensure the survival and rooting of the cuttings. Vermiculite, river sand, coconut fiber, or perlite can be used as the medium for hydrangea propagation. Before propagation, place the medium in the sun for 1 to 2 days to sterilize and disinfect.
4. Propagation Process
Hydrangea propagation is relatively simple. Use a small stick to make a hole in the medium, insert the cutting into the hole, compact the surrounding soil to secure it, and then water thoroughly to complete the propagation.
5. Care and Management
After propagation, place the cuttings in a well-ventilated area with scattered light, control the temperature between 13 to 18 degrees Celsius, water when the surface of the medium is slightly dry, stop when water seeps out from the bottom of the container, keep the soil moist, and wait for about 15 days for roots to form.
