Why don't Hydrangeas bloom
Today's tip brings you knowledge about why Hydrangeas don't bloom and cultivation methods and precautions in the field of flowering plants. Let's share the detailed content next.
Many people plant Hydrangeas on their balconies and courtyards. It is also known as绣球花 (Xiu Qiu Hua), or "Eight Immortals Flower," belonging to the deciduous sub-shrub plant. Its flowers are corymbs, spherical in shape, and can be white, blue, green, pink, etc. The color can change by adjusting the soil. The blooming period is relatively long, with a single plant lasting up to several months. They usually start blooming in spring, and some varieties bloom in summer. When spring comes, some friends get worried when they see their Hydrangeas not producing flower buds. Why is that?
There are three reasons why Hydrangeas don't bloom.
First: The blooming period has not arrived yet. Temperature is an important factor affecting the blooming period. Low temperatures can cause the blooming period to be delayed, so be patient, and a little more patient. If there are still no flower buds on the branches and leaves at the blooming period, or if the potted Hydrangea is thin and small, the focus should be on supplementing nutrients in time to make the plant more lush and full, which will help it bloom smoothly.
Second: Supplement lighting in time. If Hydrangeas still don't bloom at the blooming period, it might be due to insufficient lighting. Although Hydrangeas are shade-loving plants, they should be kept in a cool place in summer and brought out to bask in the sun in spring. Increased lighting can prevent leaf yellowing and excessive leaf growth without blooming. Sufficient sunlight allows the flower buds to differentiate smoothly and the flowers to be larger.
Third: Supplement fertilizers in time. Hydrangeas like fertilizers. If the seedlings are small and weak, they will find it hard to bloom. During these months in spring, before flowering, it is a period of vigorous growth, so fertilize every half month with organic fertilizer water or other slow-release compound fertilizers. When there are flower buds, add 0.5% calcium superphosphate to the fertilizer water to make the flowers larger and more colorful.

Fourth: Supplement water. As Hydrangeas grow quickly with many large leaves, they require a lot of water. In spring, water should be sufficient to keep the soil moist, but avoid overwatering. During rainy periods, if there is waterlogging in the pot, it should be drained in time.
Fifth: While supplementing fertilizers, if the Hydrangea has not been repotted for one or two years, it is best to repot it early in spring. When repotting, remove some of the old soil and, during repotting, combine pruning and apply a generous amount of bottom fertilizer. This way of growing Hydrangeas can make them bloom more and larger, as beautiful as绣球花 (Xiu Qiu Hua)!
