How to propagate hydrangeas by cuttings to achieve a high survival rate

Hydrangea, also known as hydrangea, has large, bright flowers in pink, purple, blue and other colors. It has a high ornamental value and is a popular flower today. If you want to grow hydrangea, in which month should you plant cuttings? How to plant cuttings?

Hydrangea cutting time

April to June in spring and September to October in autumn are the hydrangea seedling raising period. At this time, the branches are strong, the water is sufficient, and there are enough nutrients, so they can take root quickly and survive. In addition, the temperature at this time is also very suitable for hydrangea to take root.

Hydrangea cuttings and planting methods

1. Branch selection

When choosing branches for cuttings, do not choose withered and weak ones. Choose branches that are full and strong, free of diseases and pests, and have buds and buds for cuttings. This way, they can take root quickly, and the cuttings can sprout quickly, allowing the cuttings to form faster.

2. Branch processing

In order to reduce water evaporation, cut the branches into small sections of about 10 cm, remove all the leaf bottoms, and keep 2 leaves at the largest. In order to increase the water absorption area and improve the survival rate of the cuttings, use a blade to cut them obliquely into a horseshoe shape.

You can also apply some rooting powder on the bottom of the branches, or soak them in rhizome liquid for five minutes and then take them out, which can effectively prevent fungal infection. Finally, place the branches in a ventilated place and wait for them to dry.

3. Cutting soil

Use plain soil for cuttings, which refers to a medium that does not contain any nutrients, such as river sand, perlite or vermiculite. It is free of pathogens and organic matter, is not prone to black rot, and has a high infection rate.

4. Cutting method

Choose a flower pot of appropriate size and cover it with plain soil. There should be more drainage holes at the bottom of the pot to facilitate ventilation and avoid root rot caused by excessive water. When planting cuttings, be careful not to insert the cuttings directly into the medium, otherwise it will easily damage the base of the cuttings and affect rooting.

First, use a bamboo chopstick to make a hole, then insert the cuttings into the 1/3 position, then gently press the surrounding soil, and then use a spray bottle to moisten the medium, and place it in a cool and ventilated place for maintenance. In about a month, a lot of roots will grow from the bottom. If you have a rooting agent, it is best to dip it in a rooting agent, but if you don't have it, it's OK.

5. Transplanting and planting

When the roots grow to three or four centimeters, they can be transplanted. Hydrangea roots are fragile, so you must be careful when transplanting them. Fill them lightly with loose and breathable soil, and do not press them with your hands to avoid damaging their fragile roots.

After transplanting, place it in a place with scattered light. It will take about 7 to 10 days for the seedlings to grow normally. Hydrangeas cannot bloom in the first year, and generally bloom in the second year. In order for the cuttings of hydrangeas to bloom smoothly, maintenance work must be done in daily management, and attention must be paid to watering and fertilizing.
