When does the 八仙花 (Hydrangea) bloom?
This article focuses on the blooming time of Hydrangea and the green plant cultivation methods and precautions for growing Hydrangeas, with detailed information as follows:
Hydrangea is also known as绣球花 (Oriental Hydrangea), 粉团花 (Powder Puff), 紫绣球 (Purple Hydrangea), 草绣球 (Herb Hydrangea), 紫阳花 (Purple Sunflower), etc. The Hydrangea flower is large and full, with bright and colorful petals, and has a special fragrance. It is an ornamental tree that can be grown as a potted plant in gardens, balconies, and other semi-outdoor areas. The blooming period of Hydrangea is from June to August.
Hydrangea is a relatively common garden tree, especially in the gardens of Jiangnan region in China, where it has been cultivated since the Ming and Qing dynasties. Now, many parks have planted large areas of Hydrangeas, which are pruned into beautiful shapes with high ornamental value. So, how to grow Hydrangea well? Today, let's introduce the cultivation methods and precautions for growing Hydrangeas.
I. Cultivation methods for Hydrangea
1. Soil: Hydrangea prefers to grow in fertile and loose soil, especially well-drained sandy soil. To make the flowers more colorful and robust during the blooming period, we can use a mixture of sandy loam and leaf mold soil to create nutrient-rich soil for its growth.
2. Nutrition: Hydrangea is a plant that thrives in neutral soil but can also grow in slightly acidic or slightly alkaline conditions. Interestingly, when the soil is acidic, the flowers tend to be more blue, while in alkaline soil, they tend to be more red. Therefore, we can use sulfate aluminum to make the flowers red or lime water to make them blue. In addition, before the blooming period, we can use some compound fertilizers or homemade fertilizer cakes, or even add some leaf mold soil to supplement the nutrients in the potting soil, which can promote more and prettier flowers.
3. Watering: Hydrangea likes to grow in moist soil, but for potted Hydrangea, the frequency of watering should be controlled, following the principle of watering when the soil is dry and after it has been watered. Avoid积水 (standing water) to prevent root rot. Outdoor potted plants need to be drained after rain to avoid waterlogging. For ground-grown Hydrangea, as long as it is not in a low-lying area, there is usually no need to worry about积水 or drought. In the summer, more water can be added, which differs from the watering of potted Hydrangea.
4. Light: A warm semi-shaded environment is the best for Hydrangea growth. Such an environment keeps the soil moist and suitable for Hydrangea growth, while the moderate or short duration of sunlight prevents the plant from being sunburned. Therefore, it can be planted in the corner of the courtyard or on the balcony. Note that Hydrangea is not suitable for indoor cultivation.
II. Precautions for cultivation
The above introduces four important aspects of Hydrangea cultivation. In addition, there is one thing that needs special attention: Hydrangea is not suitable for indoor cultivation, not because the indoor growing environment is not suitable, but because it has some toxicity and can cause abdominal pain if ingested.
Also, Hydrangea is a plant with a special fragrance. If kept indoors for a long time, the scent can cause discomfort, especially in bedrooms where such fragrant flowers should not be cultivated.
Finally, some may ask why there is no mention of temperature for cultivation. In fact, when growing flowers, issues like temperature and climate are determined by the overall environment. As long as it is kept in a controllable environment, temperature becomes less important.
The above is the information about when Hydrangea blooms and the cultivation methods and precautions for growing Hydrangea, for reference by green plant enthusiasts, hoping to solve your problems in green plant and flower management.
