Fig. 4.—A Genoa lemon grafted onto a sweet orange tree about 7 years previously, when the sweet orange tree was about 10 years old. The graft unions can be seen above the white lines on the tree trunks. This grafting was done in the spring, only half of the tree being headed back and crown grafts inserted. The following season the balance of the tree was treated in a similar manner.
