  2. Don’t prune into old wood having no leaves or needles
  3. Prune during growing season to make more compact or dense
  4. To avoid reducing berry production, don’t prune during bloom period
  5. Prune to prevent oak wilt infection
  6. Prune to remove cankers
  7. Flower buds set on previous season (old) wood; winter pruning will reduce spring flowering
