We have two ES hydrangeas and both of them have not bloomed since the the year they were planted. The first was planted in partial sun/shade and did not do well, so it was moved to a sunnier area. It has not bloomed or done anything in two years. The second one was planted a year later, according to instructions, continued to bloom the rest of that year, and did not come back this year. Can anyone give us some advice? I have tried other help forums, all to no avail...all I have are ugly brown sticks left of what used to be two beautiful blue hydrangea babies. Please advise!!!
