How big will it grow?
What conditions does it need - sun, shade, soil type, feeding, mulching, watering, pruning?
How long before it will fruit and how long until it reaches full fruit production?
Is it self-fertile, double grafted or does it need a pollinator? (Self-fertile trees will produce good crops but may do even better if there is a second suitable cultivar or the same species planted nearby.)
Will it grow in a pot? Not everyone wants to grow fruit trees in pots, but there are advantages. They enhance outdoor living areas, fit into small spaces, can be moved around to find the place that suits them best, the fruit is more easily protected from birds and, best of all, you don't have to go far to pick it.
