Q.Hydrangeas
I had a gardener plant three small Hydrangeas (Blue/White blooms) in May. The plants are in partial sun and shade on the side of my home. I water them every morning for 10 minutes (during the sprinkler cycle). Many of the blooms have grown very large which is causing the stems to fall to the ground. What do I do to correct this or is it okay for the stems to be laying on the ground? Also, many of the blooms are turning brownish and seem like they are dying. Is it advisable to cut the blooms off right below the bloom (leaving the the stem bare) or will the blooms just die and fall off?
It is common for the flowers to become heavy and lean or fall.
