I have several bushes that have long branches (from 12 inches to 3 feet)
where there are only leaves on the top. The shrubs are buckthorns,
ashleaf spirea and beauty bush. The person at my local nursery said to
"flush" them but cutting them all the way down but honestly, if I do
that, I'll have nothing left on the bush since the majority of branches
on each of these bushes only have leaves at the top. Does anybody know
what I should do?
