|Hydrangeas need a few hours of morning sun in order to develop flowers and they produce flowers on new growth that sprouts from old wood. Try pruning your hydrangea back to encourage new flowering growth and make sure it is getting morning sun but shelter from hot afternoon sunshine. You can also try feeding with a bloom boosting fertilizer (such as a 10-20-10) to encouraging flowering. Hope this information helps!
