How to Grow Hydrangeas? Detailed Guide to Cultivation Methods and Precautions

SummarySoil: Hydrangeas like to grow in fertile, well-drained, loose sandy loam, and the pH value should not deviate too much. Light: They need light but it must not be too strong, otherwise the hydrangeas need to be given appropriate shade. Temperature: They are not suited to surviving at 15 degrees; in winter they must not go below 5 degrees; flower bud differentiation requires about 6-8 weeks at around 5-7°C; temperatures above 20°C can promote flowering, but if the temperature is too high, the flowers will fade.

Hydrangea is a flower variety with very high ornamental value, and it is currently distributed in many places in our country. The appearance of the hydrangea is like little balls, very beautiful. Nowadays many people have also started growing hydrangeas, but before growing them, most people surely want to have a comprehensive understanding of its cultivation techniques!

How to Grow Hydrangeas

1. To grow hydrangeas well, the first thing is to find good soil. Hydrangeas most like to grow in fertile, well-drained, loose sandy loam. The soil pH value should not deviate too much; if it is too great, it will make the color of the hydrangea change greatly.

2. Hydrangeas need light, but their dependence on light is not very strong; on the contrary, if the light is too strong, the hydrangeas still need appropriate shade.

3. Hydrangea is a warmth-loving flower; it is not suited to surviving at 15 degrees. In winter, the temperature must not go below 5 degrees at the lowest. Flower bud differentiation requires at least 6-8 weeks at 5-7°C, and temperatures above 20°C can promote flowering. The flowering period is best at 16 degrees; if the temperature is too high, it may cause the flowers to fade quickly.

Cultivation Methods and Precautions for Hydrangeas

I. Cultivation Methods

1. Hydrangeas, like other flowers, greatly dislike root rot, so special attention is needed when watering, and there must be no waterlogging. The pot soil of hydrangeas should be kept moist. If it is potted, the bottom of the pot must have drainage holes, and watering should not be excessive. If it is planted in the ground outdoors, then in the rainy season attention should be paid to drainage to prevent waterlogging from causing root rot. In winter, potted plants are better kept slightly dry. If it is too damp, it may cause the leaves or roots to rot.

2. Hydrangeas generally do not need fertilizing. If conditions allow and you want to fertilize, then applying 1 dilute cake fertilizer water every half month is enough. Never over-fertilize; an appropriate amount is fine.

3. If you want hydrangeas to have stronger ornamental value, then pruning the hydrangea is a necessary task. After the hydrangea blooms, it is best to remove its flower stems. After the hydrangea blooms, attention should be paid to removing the flower stems to encourage new branches. Proper pruning can keep the plant shape graceful.

II. Precautions

It is best to repot and change the soil once a year for hydrangeas, as this can ensure their growth. Because as we said above, hydrangeas like loose soil. After the plant is moved into a new pot, the soil should be pressed firm, then watered thoroughly, and placed in a shaded place for about 10 days. Finally, move the hydrangea outdoors and carry on with management.

When growing hydrangeas, you first need to have a good understanding of its temperature, as it likes to grow in a warm environment. Then you also need to do a good job in aspects such as fertilizer, water, and pest and disease control. Only by doing all of these well can its growth be ensured.
