Hydrangea cultivation methods and management

Hydrangeas , also known as hydrangeas, are known for their spectacular ball-shaped flowers and rich colors. Hydrangeas are now planted in many parks, and they attract many tourists to check in during the flowering season. Let’s learn about the cultivation and management of hydrangeas.

1. Suitable flowering conditions

Hydrangea usually blooms from April to July, and most varieties require low temperatures (5 to 10 degrees Celsius) to promote flower bud differentiation. In the south where the temperature is higher, there may be problems with little or no flowering. As a short-day plant, flowering can also be successfully induced by controlling the temperature and light duration (around 20 degrees Celsius, with more than 10 hours of darkness per day).

2. Soil selection

Choose loose, fertile, well-drained soil. In greenhouses , a mixture of bark, coarse coconut peat and perlite is often used to ensure that the soil is breathable and rich in nutrients while maintaining good water permeability.

3. Watering management

Keep the soil moist, but avoid standing water. Ensure good ventilation and water thoroughly after the topsoil is dry. Lack of water can cause leaves and flower buds to wilt, and even flowers to dry up.

4. Soil pH adjustment

The soil in the north is alkaline, which may affect the color of the flowers. Use aluminum sulfate or ferrous sulfate to adjust the soil pH to make the flower buds appear blue. Start using when flower buds are about to appear and replenish twice a month.

5. Pruning tips

Both new and old branches of varieties such as Endless Summer can bloom and can be pruned at any time. Other varieties recommend pruning after flowering to encourage new growth and flowering the following year. Avoid pruning in autumn or early winter to avoid affecting flowering.

6. Lighting requirements

Hydrangeas prefer semi-shaded environments and avoid strong direct sunlight. When caring for it at home, you can expose it to mild light before 10 am or after 3 pm, or use a shade net for protection.

7. Fertilization strategy

Supplement phosphorus and potassium fertilizers before flowering to promote bud formation. After pruning after flowering, use multi-element or nitrogen-based fertilizers to promote the growth of branches and leaves. Proper fertilization helps the plants grow and bloom healthily.

8. Soil quality

Good soil is the basis for growing hydrangeas. Loose, breathable, and nutrient-rich soil helps plants grow healthily, while compacted and stagnant soil may cause root rot and plant failure.

Overall, by following these simple care tips, your hydrangea will thrive and produce beautiful flowers. With proper management, hydrangeas will grow into lush, established stands.
