Long Term:
Winter:
Shrubby hydrangeas (H. paniculata, H. quercifoiia) can be heavily pruned since they form large plants of nearly tree dimensions. Cut back all heavy branches, regardless of size before February leaving two buds on each side branch. These buds will form flowers
Spring:
Blooms on current season's growth so prune as needed in late winter to early spring

Deep watering 1-2" per week, 2-3" layer of mulch, monitoring for stress
Fall:
Continue watering, leave flower heads intact, rake up fallen leaves, apply a fresh 2-3" layer of mulch
