These are trees that have been grown for at least one season in their pots. It is often possible to lift the whole root system out of the pot and see the closely woven root which has grown in the pot. The trees themselves should look fresh. The trees will be small and seldom more than three foot. The trees should be watered and cared for as for any house plant.After Christmas they can either be planted out with a very good chance of success or they can be left to grow on in their pot, but it is much better in this case to re-pot the tree in a larger pot. It is seldom possible to re-pot trees in this way for more than one season.
