Can An Aster Shrub Be Evened Out And How ?

Question

My Blue Aster Shrub is doing beautifully but the top of one side has grown upward more than the other. Can this be fixed without killing the flowers on the taller side ?

Answer 1

It's too late when it is blooming, but in mid spring to early summer, you can pinch it back as it grows to achieve a desirable shape.
