How to propagate hydrangeas through cutting
Today, the editor will elaborate on how to propagate hydrangeas through cutting, as well as the knowledge of green plant flowers regarding the timing and techniques of hydrangea cutting. Let's take a look together!
Summer is the peak blooming season for hydrangeas. After the beginning of summer, any variety of hydrangea will bloom in sequence, and basically, spring and summer are the blooming seasons for hydrangeas. At least, this is the case in the northern regions. The blooming period of hydrangeas can last for 3 to 4 months, which is quite a long time. For example, outdoor-grown hydrangeas can reach a height of 80 cm for their flowering branches, and the diameter of the open petals can be nearly 15 cm, making the blooming petals very beautiful.
After hydrangeas finish blooming, the petals will gradually wither and fall off. During this period, we need to prune them appropriately, cutting the wilted flowering branches from the bottom. This is done to retain nutrients and promote the blooming of other branches. Moreover, the cut branches can be used for propagation through cutting, as the survival rate of hydrangea cuttings is very high, much higher than that of rose cuttings.
Who among those who enjoy gardening would not want to increase the number of hydrangeas in their home? The best way to propagate hydrangeas is through cutting, including the hydrangeas bought in the market, which are also propagated through cutting. Typically, the cutting season for hydrangeas is in autumn or spring every year, as the temperature and humidity are suitable for propagation during these seasons.
For hydrangea cutting, the only conditions that need to be met throughout the entire period are temperature and humidity. Sunlight is not required, provided that clean, sterile peat soil is prepared. Peat soil purchased online can be used for cutting. Also, prepare a few flower pots or disposable cups, with transparent cups being the most suitable, as they allow for clear observation of the growth of roots inside the soil.
How to propagate hydrangeas through cutting
Buy a pack of naphthalene acetic acid rooting hormone online for a few yuan, which can be used many times. Dilute it with water according to the ratio, and cut the hydrangea branches into sections about 15 cm long. Soak the bottom cut ends in the naphthalene acetic acid rooting hormone for two minutes, then plant them directly into the flower pots.
The pots for cutting do not need to be too large, with a diameter of about 10 cm. Water thoroughly and place them in a location without sunlight. Then, just wait quietly for about 20 days. Under normal circumstances, the hydrangea branches should be able to complete root development. Do not water too frequently during the cutting process; slightly dry soil is fine, about once a week. If the soil is too moist, it can lead to the decay of the cut branches.
When the roots have grown sufficiently, carefully remove the cut hydrangea branches from the pots and transplant them into new flower pots. Place them in the sunlight for normal care. By the following spring, they will have grown and bloomed. Hydrangeas grow very fast under outdoor conditions, requiring only a short growth cycle of one year before they can bloom in the second year.
The above experience and knowledge about how to propagate hydrangeas through cutting and the timing and techniques of hydrangea cutting are hoped to be of some help to you after reading this article!
