Editor introduces you to how to propagate hydrangeas and knowledge about the timing and methods of hydrangea propagation in green plants and flowers, with specific content as follows:
Hydrangea is a shrub of the Hydrangeaceae family, and it got its name because the flowers form a ball when they bloom. The plant can grow 1-4 meters tall, with papery or nearly leathery leaves in an obovate shape with coarse teeth on the edges. The flowers bloom from June to August, and the color of the flowers may vary depending on the growth environment, which can be adjusted by some methods to make them more colorful.
Hydrangeas are not cold-tolerant, and many places cannot survive the winter, so you have to buy new ones the next year. However, if you master the propagation skills, you can grow several pots of flowers, so you don't have to buy them again.
I. Propagation Time
The survival rate of hydrangea propagation is related to temperature, and it is easier for cuttings to root and germinate in warmer climates. Generally, it is chosen in spring and autumn, from April to July in spring, and from September to October in autumn. At this time, it has just bid farewell to the blooming period, and the temperature has not yet dropped, so propagation is relatively suitable. One benefit of propagating after flowering is to reduce the nutrient consumption of the original plant, and pruning can better preserve nutrients, which helps it survive the winter.
II. Cutting Treatment
First, find a healthy plant without diseases or pests, and cut a sturdy semi-woody branch from it, with 2-3 buds. Remove all the lower leaves, leaving only the top two, to reduce moisture loss and make it more conducive to the survival of the cuttings. After cutting, do not plant immediately; instead, place it in a shaded and well-ventilated area to let the wound dry. You can apply carbendazim on it to prevent infection and rot.
III. Potting Soil Preparation
Before propagating, prepare the potting soil first. Hydrangeas thrive in loose and fertile soil that has good drainage and aeration, so sandy soil is often chosen. You can mix peat soil and perlite, or add sand, and stir it well. Then, spread it in a sunny place to expose it to sunlight to kill bacteria and fungi. After that, prepare an 8-12 cm pot and fill it with potting soil.
IV. Propagation Process
After the cutting wound is dry, propagation can begin. First, make a hole in the surface of the potting soil with a chopstick. Do not poke it straight; it's best to have a little angle. Then insert the cutting into it and compact the soil to ensure it does not fall over. After that, spray a little water to keep the potting soil moist but not too wet. Place it in a shaded and well-ventilated area and wait for the cuttings to root.
V. Subsequent Maintenance
It takes about 20 days for the hydrangea cuttings to root. During this period, pay attention to moisturizing and expose it to a little scattered light. When roots grow, you can expose it to light in the morning and evening but avoid long exposure to prevent rapid water loss. Also, regularly check the moisture level of the potting soil. Water it immediately when the surface is dry to speed up the growth of the seedlings.
