Does fertilizer help it bloom?

Too much nitrogen fertilizer can encourage leaves instead of flowers. Use a balanced, slow release fertilizer in early spring.

How much sun does it need to bloom?

These plants need bright, indirect light or morning sun with afternoon shade to produce flowers.

Check these first

Check your pruning calendar to see if you cut off old wood.

Ensure the plant is getting enough light to support blooming.

Likely causes

Improper Pruning
Most likely
How to tell: You pruned the plant in late winter or spring, removing the buds that formed the previous summer.
What to do: Stop pruning entirely for one season to let the plant recover. Only prune immediately after the flowers fade in summer.
Late Frost
Possible
How to tell: The plant looks healthy, but the buds turned brown and died after a sudden cold snap in spring.
What to do: Cover your hydrangea with a frost cloth or burlap when a late spring freeze is predicted. This protects the sensitive buds from damage.

When to worry

If the plant has not bloomed for two years, it may be in a spot that is too shady or it is being pruned incorrectly. It is normal for young plants to take a year or two to establish before blooming.

Stopping it coming back

Only prune your hydrangea right after the flowers fade, and protect it from late spring frosts with a cover.
