Q.What Can I Do With A Droopy Limelight Hydrangea Tree?
long slender stems with big blooms have my hydrangea tree drooping over. what can I do to prevent this next year? Severe or light pruning? My tree had such a beautiful shape until blooms got so big. Also what kind of fertilizer is best for hydrangea trees? Thank you so much.

I would recommend pruning it back to the shape you want after it's done blooming, maybe in late winter/early spring. I like to leave dried hydrangea blossoms on the plant in late fall/early winter for aesthetics and as shelter for wildlife, but that depends on your preference.
