Question - Why does my hydrangea not flower?
How do I get my hydrangeas to bloom, they are six years old and I had one bloom last year. This year nothing ?
Assuming the hydrangea is healthy, the mostly likely cause of the shrub not flowering is frost damage during winter or early spring. The buds are on the plant over the winter season, so they are vulnerable to frost damage. Avoid planting hydrangeas on a site facing east as the rising sun can damage new growth after a frosty night. If your hydangea faces east, try moving it in late autumn to a more sheltered position. Some varieties of hydrangea are more vulnerable to frost damage than others..
