Why Don't Hydrangeas Bloom
The editor introduces you to some small gardening knowledge on why hydrangeas don't bloom. Below, the editor will provide you with a detailed explanation.
Hydrangeas not blooming may be due to the plant receiving insufficient light during the growth process, failing to stimulate the plant to differentiate flower buds. It could also be due to using nitrogen fertilizer alone when fertilizing the hydrangeas, leading to the plant's excessive growth, or frequent watering, causing waterlogging and root rot in the plant, which cannot grow normally.
Why Don't Hydrangeas Bloom
1. -- Insufficient Light --
Hydrangeas not blooming may be because the plant receives weak light, preventing the hydrangea from sensing temperature changes. To make hydrangeas bloom, the plant needs to be placed in a sunny environment where it can receive sufficient light stimulation to successfully differentiate flower buds and bloom.
2. -- Overwatering --
Hydrangeas not blooming may also be due to excessive water provided to the plant during maintenance, leading to root damage and the plant's inability to provide proper nutrition to encourage blooming. Therefore, when caring for hydrangeas, it's necessary to provide water to the plant in a reasonable manner, preferably when the soil is dry.
3. -- Single Fertilization --
Hydrangeas not blooming is due to providing the plant with nitrogen fertilizer alone, resulting in excessive growth without blooming. In later maintenance, it's necessary to provide nutrients to the plant in a reasonable manner, preferably using nitrogen fertilizer during the hydrangea's growing period and phosphorus-potassium fertilizer before and after the plant's blooming period to promote better growth.
4. -- Insufficient Pruning --
Hydrangeas not blooming may also be due to the plant producing too much foliage during growth, consuming a large amount of nutrients from the hydrangea, leaving the plant with insufficient nutrients for flower bud differentiation. In this case, it's necessary to prune the hydrangea, using scissors to cut away the plant's poor-growing or dense foliage to help the plant save nutrients.
