Hi, my hydrangea plant is healthy but has only put out 1 flower in last 4 years. Do I need a second plant to make it flower? Thanks! Darlene

Should not need a second plant but after blooming you can trim the bush. Then this fall after leaf drop mix one tablespoon of Epsom salts to one gallon of water and pour on the soil around the base of the plant to soak the ground. In spring do the same just as the leaves are starting to emerge. This seems to work for us.
