This is why the Silva Cell system is flexible in all three dimensions to respond to different spatial limitations. Unlike many other ornamentals, Cleveland Pears have a fast growth rate. Later work on urban trees that were planted in more compacted soils more often found very shallow, horizontal root systems. Early studies of tree roots from the 1930s, often working in easy-to-dig loess soils, presented an image of trees with deep roots and root architecture that mimicked the structure of the top of the tree.
