I would go with the right fertilizer. You might have been using the kind that works on the roots (nitrogen based) and not the flowering. The 10-10-10 should be fine or ask at a local nursery if you want to really push the blooms.

EasyInstructionsThings You'll Need:
Pruning shears
Garden gloves
Chicken wire
Shovel
Fertilizer
Water
Step 1Find out if the hydrangeas are the type that bloom off of old wood-growth from previous years. Hard winters can damage old growth, causing it to die back. If this is the case, there will be no flowers during the current growing season. Protect old-wood growth by building a chicken wire cage around the plant and filling it with leaves and pine needles to help insulate the plant during the winter months.

Step 2Don't over-prune hydrangeas that bloom off of old growth in early summer or late winter because the plant will die back even further, resulting in no buds to put forth blooms. Prune in the spring when the buds can be seen.

Step 3Plant hydrangeas in shade but not too much shade. If the plant is producing beautiful leaves but no flowers then it's getting too much shade. Transplant to another location.

Step 4To much fertilizer and water or not enough fertilizer and water will cause the plant to not flower. Fertilize in early spring and early autumn using a time-release formula. A time release fertilizer mix of 10-10-10 or 16-16-16 works well.

Step 5Transplant non-blooming hydrangeas to sides of buildings or northern and eastern slopes for better protection during the winter months. Also plant under evergreen trees, which will offer good protection.
good luck.

We have two hydrangea plants that were given to us at same time. We planted them side by side at the same time. Both plants flourished, one had many blooms. The other is just green and healthy looking, no blooms. What can we do to make it bloom or should we just remove non-blooming plant?

How do you make hydrangeas bloom? I have beautiful lush bushes with no blooms. I do not cut them down at the end of the season.

RE: Hydrangeas Not Blooming

Sometimes if you get a frost after the buds have already formed, it can affect the blooms. What type of hydrangea do you have? A mophead? If you grow the new ones that are out like, Endless Summer to name one, they bloom on both old and new wood so you have a better chance of them blooming. Also a paniculata will bloom every time. I have two paniculata hudgrangeas called "Limelight" and they will always bloom because they are more cold tolerant. (09/17/2009)
