These are trees which have been extracted with their roots. This is usually only possible with the smaller trees. The small roots break off and no soil comes with the larger root system. They should be freshly harvested. It is best to soak the roots in water before potting the tree in moist earth. The earth should be kept moist. These trees will last longer if they are kept away from direct heat when they are brought indoors. There is a slight chance that these trees will survive if planted out after Christmas. They should be watered very well.
