Can Hydrangeas be propagated by cutting in summer?
If you want to know whether hydrangeas can be propagated by cutting in summer and the detailed methods of hydrangea summer propagation in the aspect of green plant maintenance, the editor will introduce it as follows.
Hydrangeas are generally propagated in spring and autumn, but they can also be propagated in summer, preferably during the plum rain season in June and July, and the temperature should be controlled between 13 to 18℃. When propagating, the cuttings should be selected from healthy, disease-free, apical branches with nodes, and the substrate should have good drainage and be loose and breathable. After the cuttings are inserted, they should be placed 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 Time
Hydrangeas prefer warm, humid, and semi-shaded environments and grow vigorously in spring and autumn. Propagation is generally done in spring and autumn to ensure the survival and rooting of the cuttings. It can also be done in summer, but it should be carried out during the plum rain season in June and July, and the temperature should be controlled between 13 to 18℃.
2. Cutting Selection
Good quality cuttings have a high survival rate, root quickly, and grow more robustly after potting. When propagating hydrangeas, the cuttings should be selected from healthy, disease-free, apical branches with nodes, cut about 20 centimeters long, retain the upper leaves, remove the lower leaves, and make a diagonal cut at the bottom.
3. Substrate Preparation
The propagation substrate should have good drainage and be loose and breathable to benefit the survival and rooting of the cuttings. Vermiculite, river sand, coconut coir, or perlite can be used as the substrate for hydrangea propagation. Before propagation, place the substrate 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 small hole in the substrate, insert the cutting into the hole, press the surrounding soil to secure it, and water thoroughly to complete the propagation.
5. Maintenance Management
After propagation, place the cuttings in a well-ventilated area with scattered light, control the temperature between 13 to 18℃, water when the surface of the substrate 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.
The above introduction about whether hydrangeas can be propagated by cutting in summer and the detailed methods of summer propagation of hydrangeas is complete, hoping it can help you. Also, we hope everyone comes to see more green plant and flower experience knowledge!
