A Yearling Cherry
This picture shows the remarkable qualities of form and foliage a typical Burbank cherry tree one year old. Mr. Burbank selects his seedlings always with an eye to many qualities of form and vigor of growth, and color of leaf, that the less practical plant developer might overlook. He also eliminates any plants that show susceptibility to mildew or other fungus diseases. Hence his orchards are made up of trees that are relatively immune to disease and that do not need to be sprayed.
