All varieties like well-drained soil and full sun. You will be rewarded to with kilos of fruit if you choose the most suitable variety for your climate.
All grapefruits are self-fertile and are great eaten fresh when used in preserves or marmalades. Grapefruit trees are excellent for screening or hedging, they make fantastic shade trees and are easily espaliered. Not recommended for pots.
The medium sized fruit has a red blush beneath the yellow skin as it ripens in July / August. The flavour is distinctly sweeter than other grapefruit, but still has that great grapefruit tang. The fruit makes a wonderful juice with its red / pink colour. The tree is dense and bushy and crops abundantly year after year. Originating in the West Indies, this variety has high heat requirements… so choose the warmest position possible. Leave the fruit on the tree to sweeten as long as possible.
Being a parent of the red grapefruit it is very similar, but this variety has yellow flesh. A good strong growing tree that fruits consistently.

The traditional grapefruit. Originating in NSW, the Wheeny is actually a hybrid of the Pummelo. It has large yellow fruit with a medium to thin rind and a very bitter, acidic flavour.

Once your tree is established you will be sharing the grapefruit with the whole neighbourhood in late summer.
The Thompson’s Pink Grapefruit has a large fruit with few or no seeds. The flesh can vary in colour depending on the area. Under favourable conditions it is a light pink colour.
