Pruning

  • Prune in winter when dormant for Pomegranates generally
  • Remove a little of old unproductive wood to encourage new growth annually and new fruiting growth opportunities
  • Tolerate pruning to restrict size but have tendancy to sucker from base
  • New growth to be shortened back to two sets of leaves whenever it lengthens beyond 3-4 sets of leaves
  • Shorter blob tipped shoots are those carrying embryonic flowers so do not prune these off
  • Pomegranates are very bushy so thin out every 2 months when in growth
  • Cut heavier branches in mid-summer
  • If you want flowers allow the branches to elongate longer than normal to flower and they usually appear on the growth tips
  • Prune back hard after flowering
