Maidens: These are trees that were grafted the season before. They are the smallest size you can buy, and are the basic building block for all other fruit tree sizes and shapes. You can read more about Maiden fruit trees here.
Cordons: Applies almost exclusively to apples and pears that bear fruit on spurs. Cordon fruit trees are usually grown diagonally on wires to save space. They were grafted 2-3 years before and have been pruned, so they have a main trunk that is covered in stubby fruiting spurs. Read more about Cordon apples & pears here.
Bushes: These were grafted 2-3 years before sale. They are the shape of a 'normal' fruit tree but were pruned so the first branches are between 60-80cms from ground level when planted. A bush fruit tree will reach about 3 metres when fully grown and is the ideal size for a freestanding tree in a smaller garden. Read more about Bush fruit trees here.
Half-Standards: These were grafted 2-3 years before sale. A half standard fruit tree is a normally shaped fruit tree with a straight trunk of 100-120cms before the first branches appear. When mature, it will reach between 4 and 5 metres. Read more about Half-Standard fruit trees here.
