How to propagate hydrangeas through cutting
Introduction: This article provides an introduction to the propagation of hydrangeas through cutting and the timing and methods of cutting for green plants and flowers. Next, the editor will introduce the topic to netizens.
Mentioning hydrangeas may make some people feel unfamiliar, but if we talk about绣球花 (hederachys), people immediately think of a large cluster of beautiful hydrangea flowers. In fact, hydrangeas are绣球花, a common flowering plant that is suitable for landscaping and garden beautification and is relatively easy to cultivate. The common method of propagating hydrangeas is through cutting. When done at the right time, the cuttings have a high survival rate, and the seedlings can grow into vigorous plants in the same year. Hydrangea cutting propagation is suitable for field seedling raising and is also suitable for home cultivation. Hydrangeas bloom in summer, with dense flowers, large flower shapes, and bright colors.
1. Soil
Hydrangeas prefer fertile, well-draining sandy soil. Appropriate soil should be prepared before planting, which can be special nutrient soil or a mixture of garden soil, decomposed leaf soil, and fine sand.
2. Watering
Watering depends on the condition of the soil, keeping it moist. In spring and autumn, water every two days. In summer, due to higher evaporation rates, water daily and also spray water around to lower the temperature. During the rainy season, ensure proper drainage to prevent root rot in hydrangeas.
3. Fertilizing
Fertilizing hydrangeas mainly occurs during the growing period. Apply a thin cake fertilizer every half month and add an additional 1-2 fertilizations during the bud formation stage. Adding a dip in calcium superphosphate solution can make the hydrangea flowers larger.
4. Light
Hydrangeas prefer semi-shade and should not be exposed to direct sunlight, especially in summer, as this can burn the plants. During summer, provide shade for hydrangeas, while allowing them to receive normal sunlight in spring, autumn, and winter.
5. Cutting Time
The best time for cutting hydrangeas is in spring, specifically in early March. During this period, temperatures rise and stabilize between 13-17°C, which is beneficial for the growth of hydrangeas. Cuttings made at this time take root quickly and seedlings grow vigorously.
6. Cutting Selection
Choose one-year-old branches as cuttings, focusing on those that are vigorous, strong, and free from diseases and pests. The branches should be about 10 centimeters long, cut diagonally at the bottom, and most of the leaves removed or cut in half to prevent water evaporation.
7. Substrate Preparation
For cutting, you can use selected substrates, river sand, or nutrient soil as the cutting medium.
8. Cutting Method
Spread the substrate on the seedbed or fill a container with it. Insert the prepared hydrangea cuttings into the substrate, water thoroughly after insertion, and place them in a well-ventilated area without direct sunlight. Gradually increase light exposure once the cuttings have rooted.
