My lacecap hydrangea has lovely green/white leaves, but doesn't produce the flower. This hydrangea is between two other hydrangeas that bloom great. What can I do?

Flower buds are produced on old wood for the following year's display. If your hydrangea freezes down to the ground each winter, there will never be any old wood, and your plant will probably not flower, except when it experiences a mild winter. If your plant does not freeze down to the ground, don't prune out all the old wood each year. Instead, leave the stems 18"-24" in length from the crown of the plant. In the spring when new growth begins, it will come from buds on the wood you left. In this case, the hydrangea will flower on the new shoots that were produced in the spring.
