Fruiting hedge

Hi NinaR,
I'm in Melbourne so don't know about conditions in SA but Gardening Australia's Sophie Thomson is in SA and she planted a feijoa hedge. She put plants one metre apart. Here's a link to the fact sheet on the Gardening Australia website.

Apart from feijoas, the only other evergreen hedge plant I can think of would be some of the berries. Oh, and lilly pilly. And dwarf citrus.

There are different types of hedges. If you want a neat shape with little pruning needed then grumichama is great as it has dense foliage. They are a bit slow but work well. I have seen mulberries cut as hedge and they they put a new crop nearly every time they are cut. They look reasonably neat. and there is a dwarf cultivar available. A good screen is rose apple, it is not so dense but still great and would prefer itself to reach about 2.5m tall. Feijoa can get quite twiggy when regularly cut as a hedge but not so bad if carefully managed with a combination of cutting back and thinning out- not all done at once. The Surinam cherry is a yes and no as the tidiness varies greatly. I have found that most seedlings of an orange fruiting variety give a very tidy bush and very mild sweet fruit and can settle at about 1.5m or taller. Others can go through times of leaf drop, then releaf shortly after. Some are downright ugly and need pruning similar to the feijoa. possibly at ground level. If you can find a compact Irish strawberry tree called Arbutus unedo "Elfin King", it makes a nice hedge and if you are eager as much as me the fruit are quite tolerable. They are slow so easy to care for. I wonder if a grafted finger lime would be suitable.
