4. Inadequate or Too Much Sunlight
To bloom, most hydrangeas require at least three to four hours of direct sunlight per day, ideally in the early morning or dappled sunlight in the afternoon. Locations with full afternoon sun are usually too intense. Both too little and too much sunlight can affect blooming. The panicle hydrangea can tolerate the most sun exposure.

2. Winter Damage to Flower Buds
The reason for hydrangeas not blooming is often because of frost damage to the flower buds in Spring. The emerging flower buds are particularly sensitive to a sudden drop in temperature, and late Spring frosts damages the buds and prevents the hydrangea from blooming.
3. Too Much Nitrogen Fertilizer (Reduce Fertilizer use)
If you apply fertilizer too often or in too high concentration this can cause the hydrangea to grow lots of foliage at the expense of flowers. Hydrangeas only require a well balanced fertilizer applied at the start of Spring to encourage flowers.
4. Not Enough Sunlight for Flowering

5. Hydrangea not Mature Enough To Flower
Hydrangeas often do not flower in the first year after planting as they invest their energy into developing the root system and adjusting to their new conditions rather then displaying flowers. Hydrangeas tend to bloom more the year after planting or once they have matured for a few years in the soil.
6. Not Enough Water Whilst the Flower Buds Develop
Hydrangeas require well draining, yet consistently moist soil. If the soil around the roots dries out this causes drought stress which can prevent the development of flower buds and ultimately be the cause of your hydrangea not blooming.
