Freezing Effects on Seedling Orange Trees 
A, Seedling orange trees deheaded after the freeze of February, 1917. Photographed in the 
fall of 1917. As a result of this severe cutting out of deadwood, melanose did not develop 
to any appreciable extent that year, and the trees were producing normal crops in a 
few years 
B, Small dead twig as a source of melanose infection on young orange. It is almost impos- 
sible to remove twigs of this size in pruning operations 
C, Seedling orange trees severely killed back by the freeze of February, 1917, left unpruned 
and with little care for several years. Had these trees been deheaded and given proper 
attention they would have recovered in two or three years
