I know that for more flowers a bushy plant is favored and for bigger flowers branches and too many growing points are discouraged/removed. I would rather have many flowers on a bushy plant. Also, taller plants are harder to save from brutal winds. However, how many growth points are just too many for a healthy plant. One of my Dahlia tubers is growing 8 shoots and another has 4, remaining have 1-3, so they are just fine. Should I be thinning the 8 or the 4 or they would be just fine?
