How to propagate hydrangea by cuttings?

Hydrangea macrophylla, also known as shade hydrangea or hydrangea macrophylla, is a popular perennial deciduous shrub . It is known for its large, spherical flowers and rich colors such as white, pink, purple, blue, etc. Hydrangea has lush branches and leaves and gorgeous flowers. Whether planted on a balcony or in a courtyard, it can become a beautiful landscape. So how do you propagate hydrangeas by cuttings?

1. Hydrangea cutting method

1. Choose the right cuttings

Choose one-year-old semi-lignified branches for cuttings, and avoid using old or too tender branches. Cut the selected branches into small sections of about 10 centimeters long, remove most of the leaves, and keep only a few small leaves to reduce water evaporation.

2. Selection of cutting medium

Hydrangea does not have high requirements for cutting media, and ordinary garden soil can also be successfully used for cuttings. But using a loose, breathable medium, such as peat moss mixed with perlite or vermiculite, can speed up rooting.

3. Management after cutting

After cutting, place the hydrangea in a diffused light and ventilated environment, avoiding direct sunlight. Keep the medium moist, but avoid over-wetness. Avoid frequently pulling out branches to check rooting. Rooting can usually be observed in less than twenty days.

2. Key points for hydrangea maintenance

1. Change pots regularly

For hydrangeas that have been growing for one or two years, it is recommended to repot them in early spring before flowering. Remove the old soil and trim old and rotten roots, and use new fertile and loose soil to promote the plant to absorb more nutrients.

2. Use a bracket

For large hydrangeas or those with long branches, you can use a bracket to fix them during growth or flowering to make the plants more upright and beautiful.

3. Adequate water and fertilizer

Hydrangea has large leaves and requires a lot of water and fertilizer. Before flowering, the frequency of fertilization should be increased, using sesame paste residue water, cake fertilizer water or phosphorus and potassium fertilizers, and applied once every once in a while to promote the opening of more flowers.

In short, through the above methods, you can effectively propagate and maintain hydrangeas, allowing them to bloom beautiful flowers at home or in the garden.
