Do you have tips on how to help my Strawberry Sundae® Panicle Hydrangeas to stand up straight? I’ve read that I should prune them back about 1/3 and I’ve also heard to prune the thinner branches that cross over one another. How about fertilizing?

When you prune old canes by 30-50% that remaining twiggy structure leaves a great support system in place for new, emerging stems which will help support the next year’s new growth. Don’t reduce fertilization – but do be patient. It typically takes three years for a shrub to develop a strong enough root system to support all the active top growth. During that time the shrub may appear somewhat top-heavy but it will soon become established. This video on how to prune panicle hydrangeas will help you out!
