I have a hydrangea that we will be transplanting soon. The plant grows really well every year but never gets a flower. Does it need Bloom Boost or something similar? What can I do?

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. Bloom boost won't help. Since you're moving your hydrangea, perhaps you'd rather replace it. 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. What makes Endless Summer even more appealing is that it is remarkably hardy, even to Zone 4. What's more it's proven to be more mildew resistant than other macrophylla varieties. You won't be disappointed if your replace your non-blooming hydrangea with an Endless Summer.
