A detailed guide to hydrangea growing methods, easy enough for beginners to grow well

1. Soil selection

For hydrangea soil, you can use a mix in the ratio of 4 parts leaf mold, 3 parts garden soil, 2 parts river sand, and 1 part cake fertilizer.

2. Fertilization method

Hydrangea is quite fond of fertilizer; generally during the growing season, you can apply cake fertilizer once every half month.

Hydrangea likes acidic soil, so when fertilizing it you can add a little ferrous sulfate.

3. Watering method

When watering hydrangea, there must be no waterlogging, and root rot must be prevented. In summer, water once in the morning and once in the evening. Be sure to spray water on the leaves.

4. Light requirements

Hydrangea likes shade and dislikes sun. Generally it can be placed in a semi-shaded spot for care, and must be protected from direct sun exposure.

Is hydrangea poisonous? Potted hydrangea growing methods

Hydrangea is an ornamental plant with a festive form, and it was already being cultivated during the Ming and Qing dynasties, continuing right up to the present. So, is hydrangea poisonous? How do you grow potted hydrangea? Next, Xiao Qi will share whether hydrangea is poisonous and the growing methods for hydrangea.

I. Is hydrangea poisonous?

Some attentive friends take an interest in all aspects of plants, so some people ask whether hydrangea is poisonous. In fact, hydrangea is poisonous. If you accidentally eat its stems and leaves, it can cause colic, abdominal pain, diarrhea, vomiting, rapid breathing, bloody stools, and so on. So when admiring hydrangea, be careful not to pick a few flowers just because they look nice, or even put them in your mouth for photos and so on; that is very dangerous.

II. Hydrangea growing methods

1. Soil: Hydrangea does best in loose, fertile, well-drained sandy loam. But changes in soil pH make the flower color of hydrangea vary considerably. To deepen the blue, you can apply aluminum sulfate during the bud formation stage. To keep it pink, you can apply lime to the soil.

2. Planting: For potted hydrangea, generally repot and change the soil once a year, preferably in early March. The new soil can be made up of 4 parts leaf mold, 4 parts garden soil, and 2 parts sandy soil, with an appropriate amount of decomposed cake fertilizer added as a base fertilizer. When repotting, prune the plant's root system, cutting off rotten roots, decayed roots, and overly long fibrous roots. After the plant is moved into the new pot, firm the soil, water thoroughly, place it in a shaded spot for about 10 days, then move it outdoors for normal care.

3. Fertilizing: Hydrangea likes fertilizer. During the growing period, generally apply decomposed dilute cake fertilizer water once every 15 days. To maintain the soil's acidity, you can add 1%-3% ferrous sulfate to the fertilizer solution. Regularly watering with alum fertilizer water can make the plant branch abundantly and grow green leaves; adding 1-2 applications of potassium dihydrogen phosphate during the bud stage can make the flowers large and brightly colored; applying cake fertilizer should avoid the dog days to prevent disease and pests and harm to the root system.

4. Sunlight: Hydrangea is a short-day plant; with more than 10 hours of darkness treatment each day, it takes about 45-50 days to form flower buds. In ordinary cultivation, avoid direct sunlight, and 60%-70% shade is ideal.

5. Watering: Hydrangea has large leaves and lush branches and foliage, so it needs a fair amount of water. During the growing seasons of spring, summer, and autumn, water sufficiently to keep the potting soil constantly moist. In summer, when the weather is hot and evaporation is high, besides watering sufficiently, also spray water on the leaves every day. The roots of hydrangea are fleshy roots, so watering must not be excessive, and waterlogging in the pot is taboo, otherwise the roots will rot. After September, as the weather gradually turns cooler, gradually reduce the amount of watering.

6. Pests: Hydrangea mainly suffers from wilt disease, powdery mildew, and leaf spot, which can be controlled by spraying a 600x solution of 65% zineb wettable powder. Pests include aphids and mirid bugs, which can be killed by spraying a 1500x solution of 40% omethoate emulsifiable concentrate.

How do you grow hydrangea? What are the hydrangea growing methods?

Hydrangea, also known as hydrangea and ziyanghua, is a plant in the genus Hydrangea of the family Saxifragaceae. The flowers of hydrangea are pure white and full, large and beautiful, and their color can be red or blue, delighting the eye and refreshing the mind; it is a common potted ornamental flowering shrub. China cultivated hydrangea relatively early, and hydrangea was planted in the Jiangnan gardens built during the Ming and Qing dynasties. Parks built in the early 20th century were also inseparable from hydrangea plantings. Modern parks and scenic areas plant it in large patches to form landscapes. So how do you grow hydrangea? Let's look below at what hydrangea growing methods there are.

I. The growing environment of hydrangea

Hydrangea is native to China and Japan. It likes a warm, humid, and semi-shaded environment. The suitable growing temperature for hydrangea is 18-28°C, and the winter temperature should not be lower than 5°C. Flower bud differentiation requires 6-8 weeks at 5-7°C; a temperature of 20°C can promote flowering, and maintaining 16°C after flowering can extend the flowering period. But high temperatures make the flowers fade quickly. The potting soil of hydrangea should be kept moist, but watering should not be excessive; especially in the rainy season, pay attention to drainage to prevent waterlogging from causing root rot. In winter, potted hydrangea indoors is best kept slightly dry. If it is too damp, the leaves rot easily. Hydrangea is a short-day plant; with more than 10 hours of darkness treatment each day, it takes about 45-50 days to form flower buds. In ordinary cultivation, avoid direct sunlight, and 60%-70% shade is ideal.
