Since trees at this age will be unbranched, the grower will be able to adjust the branches that form the head to much greater advantage than if transplanting isde- laj'ed until after b r a n c h e s hn ve formed in the nurs- ery. The walnut does not suffer so UHU'li from mal- formed heads as some other decidu- ous orchard trees, l3ut a well-formed head is desirable if vigorous and long- lived trees are to be grown. The details of planting are quite the same as for other orchard trees. Keep the roots from air as much as possible between nursery and or- chard. Prune otl' all bruised and broken roots with a clean, smooth, oblique cut. If possible to obtain trees from the nursery in the autumn preceding planting, root pruning may then be done advantageously before the trees are heeled in, and the wounds will be callused before planting time. The growth of the new rootlets can then proceed more quickly at the opening of the season. In recent years nnich discussion has arisen over the importance of the taproot. it is safe to say that healthy vigorous trees with a good supply of lateral roots and a short piece of taproot will nudvc as good develop- ment as one with a longer taproot. The removal of the taproot is not 254.
