Why won't Hydrangeas bloom?
A content about the reasons why hydrangeas fail to bloom, with detailed introduction below.
Why won't Hydrangeas bloom?
1. Insufficient light: Inadequate lighting during the growth period of hydrangeas weakens the photosynthesis of the leaves. 2. Low temperature: If the temperature during the blooming period of hydrangeas is below 20 degrees, it will be difficult for them to bloom. 3. Lack of nutrients: Insufficient phosphorus and potassium fertilizers applied before the blooming period. 4. Unsuitable soil: Long-term failure to loosen the soil for hydrangeas leads to soil compaction or severe salinization and alkalization.
1. -- Insufficient Light --
Hydrangeas may fail to bloom due to insufficient lighting during the growth period, which weakens the photosynthesis of the leaves and affects the blooming of the flowers. It is best to place hydrangeas outdoors in full sunlight during the maintenance period to avoid long-term dark environments.
2. -- Low Temperature --
Hydrangeas prefer a warm environment, with an optimal growth temperature of around 25 degrees. The temperature for blooming cannot be lower than 20 degrees. If the temperature during the blooming period is too low, it will make it difficult for hydrangeas to bloom. A greenhouse can be set up before the blooming period to raise the maintenance temperature.
3. -- Lack of Nutrients --
Hydrangeas have lush foliage and consume a large amount of nutrients during the growth period. The plants also need sufficient reserves before blooming. If insufficient phosphorus and potassium fertilizers are applied before the blooming period, the plants may experience difficulty blooming due to a lack of nutrients.
4. -- Unsuitable Soil --
Hydrangeas thrive in loose, fertile soil with good drainage and aeration. If the soil is not loosened for a long time, it can lead to soil compaction or severe salinization and alkalization, causing the hydrangeas to fail to bloom. It is best to change the potting soil every 1-2 years.
The above shared content about the reasons why hydrangeas fail to bloom is for the reference of green plant enthusiasts, hoping to solve your problems in green plant and flower management.
