When to propagate Hydrangeas
A comprehensive explanation of when to propagate hydrangeas and the related introduction of green plant flowers, including the methods and timing of hydrangea propagation. Below, the editor provides you with detailed answers.
Hydrangeas are generally propagated in spring and autumn. They can also be propagated in summer, but it should be done during the plum rain season in June and July, and the temperature should be controlled between 13 to 18°C. When propagating, the cuttings should be selected from healthy, pest-free, apical shoots with nodes. The substrate needs to have good drainage and be loose and breathable. After planting, the cuttings should be placed in a well-ventilated area with scattered light, controlling the temperature, keeping the soil moist, and waiting about 15 days for root formation.
1. Propagation Timing
Hydrangeas prefer a warm, humid, and semi-shaded environment. They grow vigorously in spring and autumn. Propagation is generally done in these seasons to help the cuttings survive and root. It can also be done in summer, but it should be during the plum rain season in June and July, with temperatures controlled between 13 to 18°C.
2. Cutting Selection
High-quality cuttings have a higher survival rate, faster rooting, and grow stronger after potting. When propagating hydrangeas, the cuttings should be selected from healthy, pest-free, apical shoots with nodes, cut about 20 centimeters long, keeping the upper leaves and removing the lower leaves, with the bottom cut diagonally.
3. Substrate Preparation
The propagation substrate needs to have good drainage and be loose and breathable to help the cuttings survive and root. Vermiculite, river sand, coconut coir, or perlite can be used as the substrate for hydrangea propagation. Place the substrate in the sun for 1 to 2 days to sterilize and disinfect before propagation.
4. Propagation Process
Hydrangea propagation is relatively simple. Use a small stick to make a 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, controlling the temperature between 13 to 18°C. Water when the top of the substrate is slightly dry, stopping when water seeps out from the bottom of the container. Keep the soil moist and wait about 15 days for root formation.
