Hydrangea cuttings can be started from the cutting time, cutting cuttings, preparing the substrate, inserting the cuttings into the soil, and management methods.

1. Cutting time

Hydrangea likes to grow in a warm environment, and spring, summer and autumn are its peak growing seasons. Judging from its growth habits, the best time for cutting is between March and April in spring or August and October in autumn. The climate is suitable, it is easy to manage after cutting, and it is also conducive to rooting, which can improve the survival rate.

2. Cuttings

The cuttings used for cutting must be strong and strong. It is best to choose semi-lignified branches. Such branches have strong germination ability and are conducive to rooting and survival. The cuttings do not need to be too long, each section is 15-20 cm long. After cutting, remove the lower leaves and keep the top 2-3 leaves. After processing, soak and disinfect in disinfectant water to avoid the growth of bacteria.

3. Preparing the substrate

Hydrangeas like soft, breathable soil rich in organic matter. When preparing the soil, you can mix leaf humus soil and river sand into the garden soil and mix it evenly. Afterwards, just expose it to the sun for disinfection, and ensure that the substrate is sterile and free of insect eggs before use.

4. Insert the cuttings into the soil

The substrate is ready, and the cuttings can be made after the cuttings are processed. First use a small wooden stick to poke a small hole on the surface of the substrate, dip the bottom of the cutting into rooting powder, then put it directly into the hole, compact the surrounding soil, and water it thoroughly in time.

5. Management methods

Hydrangeas can take root in a warm environment. After cutting, a warm environment must be provided. It is best to control the temperature between 20-25℃. If you find that the substrate is dry, water frequently and maintain treatment.

Do not fertilize until the roots have taken root. Apply thin fertilizer frequently after the roots begin to sprout. In addition, it is best to avoid summer and winter for cuttings. Summer is the flowering period and the temperature is high. In winter, the temperature is low, the survival rate is low, and management is relatively difficult.
