Grades coming on:

The grade size is the size of the bag/pot the tree is in. This is measured in either litres or pints per bag.

The average height is the overall height of the tree from the bottom of the trunk to the top of the tree, averaged across the trees we have in this grade.

The standard height is the height of the clear trunk from the bottom of the trunk to the graft or the first branch (if it is not grafted). If you don't want a standard tree, select 'None' as the standard height.

Grades that are coming on are not yet ready for sale. You can place a pre-order for a 50% deposit and we will hold the stock until it is ready. Enquire if interested.

Heights are given in good faith but we give no guarantee as to the height of the final product. If you would like a current photo of any of the grades, please get in touch.
