All dead and decaying wood should be removed from citrus trees, for such wood harbors fungous growths that arc likely to infest fruit and healthy branches and foliage. For example, the fungus that causes melanose and stem-end rot occurs in decaying wood. The fact that all dead and decaying wood should be removed from citrus trees cannot be too strongly emphasized. Many trees have died and much fruit has been lost m the past on account of dead wood having been allowed to remam on the trees. When removing a partly decayed branch it is well to cut back to healthy wood in order to be §27 IN GULF-COAST STATES 27 sure that all infected areas have been removed. Often infected areas exist beyond the region of apparently dead wood. All decayed twigs and branches should be removed from the grove and burned to prevent further infection. A good time for pruning trees is when they are dormant. Usually the work is done during some dormant period in the winter or in the spring after the crop has been removed. At this time many branches that may have been injured by the weight of fruit can be removed, and since the soil is likely to be in clean cultivation, the prunings can be removed easily without interference with the cover crop. In pruning citrus trees, however, a good rule to follow is ''prune whenever you see something that should come ; 33. The tools used for pruning are hand priming shears, long- handled shears, a pruning knife, and saws. Shears like those shown in Fig. 11 are used to take off small twigs and suckers; long- handled shears, known often as lopping shears, like the pair shown in Fig. 12, are used for pru
