help!! brown blooms
I am new to gardening and need to know what to do with my Mophead hydrangea. I got my plant about 2 months ago. I bought it pot planted with two opening blooms and a few buds. The weather has been 60-70s during to day. Over the last few weeks the weather got hotter and required me to water daily. I found it need water that often because if I didn't water it, at night, the blooms looked wilted. Now I water it nightly and it has 8 blooms. All the new blooms are a beautiful blue except the originals which has a few brown flowers. The plant looks healthy but I don't want all the flowers to turn brown. Was it the fact that I didn't water it often enough or is it something else?? Any advice is greatly appreciated.
