Why don't Hydrangeas Bloom
Do you know these? The related experience of flowering plant cultivation on why Hydrangeas don't bloom, here is a detailed introduction.
Why don't Hydrangeas Bloom
If Hydrangeas fail to bloom due to insufficient sunlight, they need to be moved to a sunny area for care, but they are short-day plants, requiring 10 hours of darkness each day, so light exposure should be controlled. If improper pruning is the cause, pruning of branches and leaves should be done promptly. If high temperatures are the cause, cooling measures should be taken, and water can be sprayed in a timely manner to maintain moisture. If excessive nitrogen fertilizer is the cause, additional phosphorus and potassium fertilizers can be applied.
Reasons Why Hydrangeas Don't Bloom
Hydrangeas bloom at different times depending on the cultivation area, but most bloom between June and August in the summer, with a flowering period of 25-30 days. However, there are varieties called Endless Summer and Endless Summer Bride that can bloom from June until frost stops growth.
If Hydrangeas fail to bloom due to insufficient sunlight, they need to be moved to a sunny area for care. If improper pruning is the cause, dense and overgrown branches should be pruned promptly.
If high temperatures are the cause, cooling measures should be taken, and water can be sprayed in a timely manner to maintain moisture. If excessive nitrogen fertilizer is the cause, additional phosphorus and potassium fertilizers can be applied.
Hydrangeas Only Grow Leaves, Not BlossomsHydrangeas that only grow leaves and don't bloom are usually due to excessive nitrogen fertilizer, which promotes the growth of branches and leaves but makes it difficult for flower buds to differentiate, leading to no blooms. Additionally, if pruning is not done promptly during the maintenance period, it can cause the loss of nutrients and also result in no blooms.
What to Do When Hydrangeas Don't Bloom
When fertilizing Hydrangeas, attention should be paid to a balanced ratio of fertilizer types. Nitrogen fertilizer can be applied during the growth period, but phosphorus and potassium fertilizers should be applied before blooming to promote the differentiation of flower buds, which will increase the number of blooms. In the summer, when sunlight is too strong, proper shading should be provided, and in other seasons, they can be placed in a location with ample diffused light for care.
Hydrangea Planting and Blooming Methods
Hydrangeas should be watered moderately to maintain a moist state, and drainage should be considered during the rainy season. If the roots rot, it will affect blooming. After each watering, they can be placed in a well-ventilated area to speed up water evaporation.
Hydrangeas are short-day plants, requiring 10 hours of darkness each day, so the duration of light exposure should not be too long.
