Spirea

Question

Why are my spirea bushes growing up but not out? Thinking maybe they were not cut correctly

Answer 1

Unfortunately, Your photo didn't come through. If your spirea is growing up but not out, it's likely due to pruning issues—either cutting only the tops or pruning at the wrong time. To fix it, do a hard cutback in early spring to encourage bushier growth, or thin out older stems to open the plant up. A fall pruning that is more aggressive can further help shape it. Spirea loves sunlight and responds well to rejuvenation, so with proper timing and technique, it'll bounce back fuller and more balanced.
