This first year, plan to give them a good soaking from time to time to help the hydrangeas grow good roots. Really watch them on the hot, sunny days. On those days, give them a little bit of extra water. When the hydrangeas are putting on buds and flowering, they will need a little bit of extra water to help them with the energy they need. Once you get them through this summer and get the roots developed, they won’t need as much water next year. For now, a good soaking one morning and a week of cooler temperatures will help them recover.
