Answer: The most common reasons for non-blooming hydrangeas is lack of sufficient sunlight and excessive nitrogen fertilizer. Hydrangeas need about 4 hours of morning sunshine in order to bloom. If they are planted near a lawn that you regularly fertilize they may be getting an overdose of nitrogen fertilizer which will encourage lots of lush, green growth at the expense of flowering. Hope this information helps you determine just why your hydrangea is not blooming.
