How to grow hydrangea and what to pay attention to

Hydrangea growth habits

Hydrangea prefers a warm, humid, well-ventilated semi-shady environment. The suitable growth temperature is between 18 and 28 degrees. The wintering temperature needs to be above 5 degrees. It is suitable for planting in loose, fertile and well-drained sandy loam. The soil should be kept moist at ordinary times and drainage should be ensured during the rainy season.

Light requirements: Hydrangea has very high requirements for light. The light should not be too strong or too weak, and the lighting time should not be too short, otherwise it will affect its flowering and growth. When caring for it, you need to pay more attention to the light conditions of the hydrangea and keep it moderate.

Hydrangea cultivation method

Hydrangea is suitable for planting in loose, water-retaining, permeable, fertile and slightly acidic soil. It has high requirements for water and also likes an environment with high humidity. It needs to be replenished with water in time. The daily light time needs to be 3-6 hours. The most suitable temperature is 18 to 28 degrees. Pruning work should also be done well, especially for large-flowered hydrangeas.

Watering hydrangeas: Hydrangeas need to be watered according to the season. In summer, the demand for water is high, so watering is needed every day. Try to do it in the morning or afternoon. In spring and summer, water every 1-2 days to keep the soil slightly moist.

Fertilizing hydrangeas: Hydrangeas can be applied with organic fertilizers or compound fertilizers. More nitrogen fertilizers should be applied in the early stages of growth, and phosphorus and potassium fertilizers should be added before flower bud differentiation. You can also spray potassium dihydrogen phosphate on the leaves. Stop fertilizing after the flower buds are translucent. Generally, organic fertilizers should be applied once every half a month.

Hydrangea pruning: Hydrangeas grow vigorously and need to be pruned in a timely manner. During the growth period, the overgrown and dense branches and leaves can be cut off, and the withered flowers should be pruned off after the flowering period. This can reduce the loss of nutrients and enhance the ornamental value of the plant.

Hydrangea cuttings: When taking cuttings of hydrangea, choose thick branches close to the root system. Do it in February when winter turns to spring. Trim off the excess leaves at the bottom. After cuttings, place them in a cool, dark place. Make sure the soil is moist and the temperature is around 15°C.

Hydrangea maintenance precautions

Hydrangeas are suitable for planting in acidic soil. If the soil is alkaline, add one or two drops of salt-free vinegar when watering to lower the pH value of the soil. During the growth period, they need to be pinched and topped in time to promote the growth of side branches. They should be cut short before winter so that they can survive the winter smoothly.
