Q: My red-twig dogwood stems don't seem to be as bright red as they used to be. What is the problem?
A. As red-twig dogwood stems age, they turn dark in color. The best way to maintain your plant's health and maximize its color is to prune it using a technique known as "renewal pruning." Before the plant breaks dormancy in the spring, remove one-third of the oldest, largest stems. This will encourage new stem growth and vibrant color.
