I have a hydrangea that will not flower. It is a beautiful plant, very green and healthy, but it does not flower. I don't cut off the stalks because I read the plant flowers on last year's growth. What is wrong?

If you have a big leaf hydrangea (Hydrangea macrophylla), it blooms on new shoots that develop on old wood. If the plant regularly dies down to the ground each winter, there will be no old wood and therefore no flowers. A better choice for your area is Endless Summer. Endless Summer is a perpetual flowering big-leaf Hydrangea that blooms virtually all season long. And because Endless Summer can flower repeatedly on new wood, you can be confident that regardless of whether the plant dies back to the crown or is trimmed at the wrong time, you'll still get wonderful flowers that grow all season. If your hydrangea refuses to bloom, you may want to replace it with a more hardy variety that blooms on new wood rather than on old wood.
