Can hydrangeas be propagated by cutting?
A small piece of practical knowledge, introducing whether hydrangeas can be propagated by cutting and the cutting time and cultivation methods of hydrangeas in the field of flowers. Next, the site editor will introduce to the netizens.
Hydrangea is a shrub of the Hydrangeaceae family, Hydrangea macrophylla. It got its name because it forms a flower ball when blooming. The plant is 1-4 meters tall, with papery or nearly leathery leaves in the shape of an inverted ovate with coarse teeth on the edges. The flowers bloom from June to August, and the color of the flowers can vary depending on the difference in the growth environment, which can be adjusted by some means to make them more colorful.
Hydrangeas are not cold-resistant and cannot survive the winter in many places, so you have to buy new ones the next year. However, as long as you master the cutting skills, you can grow several pots of flowers, and then you won't need to buy flowers anymore.
I. Cutting Time
The survival rate of hydrangea cuttings is related to temperature. In warmer climates, cuttings are more likely to root and sprout. Generally, spring and autumn are chosen, from April to July in spring, and from September to October in autumn. At this time, the flowering period has just ended, and the temperature has not yet dropped, so cutting is relatively suitable. One benefit of cutting after flowering is to reduce the nutrient consumption of the original plant, and pruning can better preserve the nutrients, helping it to survive the winter.
II. Cutting Treatment
First, find a strong plant without diseases or pests, and cut a sturdy semi-woody branch with 2-3 buds from it. Remove all the lower leaves and retain only the top two, which can reduce water loss and is more conducive to the survival of the cuttings. After cutting, do not plant immediately, but place it in a shaded and well-ventilated place to let the wound dry, and you can apply carbendazim to avoid infection and rot at the cut.
III. Potting Soil Preparation
Before planting, the potting soil should be prepared first. Hydrangeas thrive in loose and fertile soil, requiring good drainage and breathability. Therefore, sandy soil is often chosen, and a mixture of peat soil and perlite can be used, or sand can be added. After thorough mixing, spread it in a sunny place to dry, which can kill bacteria and fungi. Then, prepare an 8-12 cm flower pot and fill it with potting soil.

IV. Planting Cuttings
After the wound of the cutting is dry, it can be planted. First, make a hole in the surface of the potting soil with a chopstick, not straight, preferably at an angle, then insert the cutting into it, press the soil firmly to ensure it doesn't fall over. Then 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
The cuttings of hydrangeas take about 20 days to root. During this period, it is important to keep the soil moist and expose it to some scattered light. When roots appear, it can be exposed to light in the morning and evening, but should not be exposed to long periods of sunlight to avoid rapid water loss. Also, check the moisture level of the potting soil regularly. When the surface is dry, water should be added immediately to speed up the growth of the seedlings.
