Answer: If you just planted your hydrangea, it just needs more time to establish its roots. Once it does, it will stay upright. If it has been in the ground for more than a year and it still wilts, it may be getting too much sun. Hydrangeas need morning sun but appreciate shelter from hot afternoon sun. They tend to wilt in hot sunshine but usually recover by the next morning. Hope this information helps!
