Fruitylicious1 says... Hi Brownthumb Between 3-6 meters apart between trees with a minimum of 2 rows which should be between 2-4 meters apart between rows. Happy gardening :-)	About the Author Fruitylicious1 TAMWORTH,2340,NSW 13th April 2018 10:20am #UserID: 16885 Posts: 709 View All Fruitylicious1's Edible Fruit Trees

brad16 says... How big an area are you wanting to shield (suburban backyard or rural property)? And are you in a bushfire prone environment? Casuarinas (and Allocasuarinas) are flammable. Although they are good for windbreaks, they are fuel for bushfires. I have a few Allocasuarinas (mainly littoralis) all over my place, and they go up like a bonfire. They are also very heavy seeders, and if you don't want new trees popping up here and there, then you'll be pulling up a lot of seedlings. You also mention privacy, so I'd have to mention that they can grow tall and may not provide much of a visual screen at the bole (trunk) level. Just inter-plant some other small shrubs. 'Sheoaks' are nitrogen fixers, so all the better. On the plus side, if they won't be between you and a bushfire, they are good windbreaks. They filter and diffuse, rather that deflect and cause turbulence. If it's for a backyard, you'd probably be wanting a single row windbreak right? If so, they'll have to be a bit closer together to be an effective screen. Maybe 3 metres. Keep in mind that this would be my recommendation for mature trees. Really, an effective solution would require at least 2 rows (I'd want 4, but would settle for 3). Each tree in the row 5 metres apart and the next row 3.5 metres away, with each tree staggered between the trees in the previous row. So you can see why asked about how much space you intend shielding, because 4 rows at 3.5 m apart is a 14 m deep windbreak. No-one is going to plant that in a backyard. In a backyard, with a single row, I think anything closer than 3 m is pushing it. Even 3 m will be crowding them when they mature. Anyway, just my opinion, but do keep in mind the fire potential if you live in a bushfire prone area.
