I would like to grow nectarine, pomegranate and Lemon. I don’t have any personal choice for selecting these. But the reason behind it is, my friend had grown these tress with the suggestions from http://www.gardeningnorthside.com.au/ and then after these tress were grown up, his dead backyard converted into a green heaven with their mesmerizing smell.

We have a lemon tree in our backyard and it has been there for years and hardly any maintenaince needed except to trim it now and then and keeping any eye out for ripe lemons. I think any citrus fruits are quite good and the longitivity of the trees are very long . Maybe plant a lime or orange tree as I heard they are not bad either and are low maintenaince . Check out Bunnings when you have a chance , there should be a horticulturist staff that can assist you .

Apple pear and orange OR apricot plum and nectarine

Stone fruit trees, especially peach and nectarine get curly leaf, a lot of the leaves drop off leaving the fruit exposed to be burnt by the sun. The fruit may even cook against the stone in really hot weather. We had it happen. Most embarrassing was we gave some to friends too. They weren’t usable.

I gather you have space as an issue? What do you love eating the most?
I’m not sure if I could stick to just 3. Probably orange, mandarin, & fig.

We find ‘Lots-A-Lemon’ and ‘Lots-A-Lime’ are great producers and they are a compact tree, suitable for pots or in the ground. Hardy.
Oranges. There are compact varieties, but we’ve got a Washington Naval and Valencia.
If you love figs, try a Brown Turkey Fig. They are deciduous, but produce a great crop for months, easy to cut back, & only a few ripen at a time so you don’t have a glut of fruit. They do love water though, to produce larger fruit.
Mandarin. Lots of varieties. We prefer the loose skin, but have several varieties, some early season and others late season.
Mangoes will grow into quite large trees but drought tolerant, and relatively pest free.
Peach. They are deciduous and then erupt into beautiful pink flowers. Peaches do need to be sprayed for pests to be totally grub free and fruit fly free, or take your chances and cut out the bad bits from them.

Tahitian lemon, mandarin and pomegranate

Lemon, Lime and Orange (love citrus fruits).

Lemon, lime and then a suggestion from the nursery/garden centre for something that is just a little different.

Lemon, apricot and plum – all family favourites and great for cooking.

Eureka Lemon, Blood Orange, Tahitian Lime

We like lemons (always useful), figs (great producers) and oranges (nothing like homegrown). I say this 3 due to size and relative ease of growth and production. Other trees are very prone to problems in urban areas (or thats what I have found). We avoid mulberries, as although they fruit well, they are a very messy tree!
