I don't know where my brain was when I planted my hydrangeas a few weeks a go. I didn't think about spacing much at all. I need advice on what to do now. How far do I need the plants from obstables like walls? How far apart do my plants need to be? I know it might vary a bit by type but some general info would still help me. Also, I planted two hydrangea together like they were one plant so do I need to seperate them? Do I move them now or do I wait until fall or next spring? They are doing well where they are now but now they have small root systems that would be easy to deal with so what do I do now? HELPPPPP!
