How to propagate hydrangeas through cutting
This article brings you topics related to the propagation of hydrangeas, including cutting methods and watering techniques for hydrangea cultivation. Let's follow the editor to see the specific content!
Hydrangeas are ornamental flowers favored by many people. They usually bloom in spring with a long flowering period and a variety of colors, making them very beautiful. Therefore, many people enjoy growing them. To propagate hydrangeas, you can either sow seeds or use cuttings. Below is an introduction to the cutting method for hydrangeas.
Hydrangea cutting method
1. Cutting time
Hydrangeas can be propagated by cutting at any time, as long as the temperature is around 20 degrees, not lower than 10 degrees, and not higher than 30 degrees. Spring and autumn are usually chosen for cutting, as the weather is cool and conducive to survival.
2. Branch selection
The cutting branches can be the top tender branches, which have strong vitality and more vigor, allowing for faster rooting. When taking branches, it's best to use a sharp pair of scissors or a craft knife to avoid damaging the bark and epidermis of the branches and buds.
3. Branch treatment
Apply some rooting powder to the bottom of the selected branches or soak them in a rooting solution for five minutes before removing them. This can effectively prevent fungal infections. Finally, place the branches in a well-ventilated area to dry before planting.
4. Planting method
Choose a flower pot of the appropriate size and line it with loose, well-draining soil. Insert the treated hydrangea branch vertically into the pot. The bottom of the pot should have more drainage holes for better aeration and to prevent root rot caused by excessive moisture, which can affect the growth rate after planting. Water thoroughly after planting, and later, frequently spray water to maintain humidity and place the pot in a scattered light area. The branches will root quickly.
5. Transplanting
After cutting, if the branches have rooted, do not transplant them too quickly. If transplanted too soon, the leaves may be small, and the roots not strong enough, leading to difficulty in adapting to the new pot and possibly causing leaf drying and death. Wait until the cuttings have fully survived and absorbed nutrients through new roots to grow new branches before transplanting. During transplanting, take more soil to reduce root damage, which will greatly increase the survival rate.
Notes on hydrangea cutting
1. Sterilize the medium. The soil may carry bacteria, which can infect the cutting through the wound after planting, leading to rot. Therefore, sterilization and disinfection should be done in advance. If cutting in summer, the medium can be sterilized by exposure to sunlight. In addition to sunlight exposure and microwave heating, you can also directly spray the medium with 0.3% potassium permanganate or fungicides such as carbendazim to reduce the chance of bacterial infection and increase the survival rate of cuttings.
2. The soil should not be too moist. After cutting, water the plant with a spray bottle to avoid large amounts of water that could cause the cutting to become loose. Maintain a slightly moist state for the soil during care, and you can spray water around the plant to increase humidity, which is beneficial for the growth of the cutting.
