Spring Pruning: Hydrangea
Early Spring is a great time to prune three types of hydrangea. Hydrangea paniculata, H. macrophylla 'Endless Summer, and H. aborescens 'Annabelle' all bloom on new wood so you don't have to be concerned with cutting off the flower buds like you would be for other Hydrangea varieties like the Oakleaf Hydrangea, the Mopheads, and the Lacecaps.
Cut off all weak / thin branches and prune the remaining healthy branches back to 3 or 4 leaf buds that should be starting to form this time of year. Any branches that cross should also be rectified by removing one of the crossed branches.
