What Causes Hydrangeas Not To Bloom

A lack of blooms could mean inadequate light, too much nitrogen, too little water, or an overdose of fertilizer. Hydrangeas prefer more light than other shrubs, so it’s essential to provide plenty of sunshine for the shrub to bloom. 

Too much nitrogen can promote lush green foliage but reduce flowering, while not enough water can cause buds to dry up and drop off before they open. Ensure your hydrangea gets a regular supply of moisture to keep blooming. 

An excess of fertilizer can also prevent flowering due to its high levels of nitrogen; choose a specialized fertilizer for hydrangeas with lower amounts of nitrogen or none at all. Look for one that contains potash or phosphorous, as these aid initial growth and encourage blooming. 

Finally, poor soil quality may be hindering healthy flower development in your hydrangea. Make sure your garden soil is enriched with compost or other organic matter and that it has good drainage; this will help your hydrangea thrive and produce many blooms year after year!
