Winter is a perfect time to trim hedges. If you have a feijoa hedge give it a good trim now with hedge clippers. If you are considering planting one now is a good time. Why not choose an edible option over the bog-standard pitto, Camilla, Photinia, or Grisilinia? There are so many other edible options out there which will provide screening and a crop as well. Here are some suggestions: dwarf citrus, dwarf apple, bay, tea (camellia species), pomegranate, coffee, hazelnut, currants and gooseberry, blueberry or rosemary.
