Only the one time?Every year I grow 1 Sungold cherry. It is in a wooden "cage" (Four 2x2 verticals with 1/2" dowels running between them to make a square about 24" on a side). It is 6' tall and by the end of growing season it has branches to the top and sticking out the sides some.
You can contain it by breaking out the suckers otherwise it will be REAL bushy
One the one time
