People often ask how running bamboo grows. Since roots, by their very nature, are under the ground, they are not easily seen and difficult to imagine. But recently some red bamboo (
Semiarundinaria fastuosa) appeared in a section of our property where we had recently cleared away several feet of soil. Since the ground had been disturbed, a nearby section of red bamboo sent runners out into the open space. While some of the roots are anchored in the very dense cayola (white clay) soil, others are exposed providing an unusual opportunity to see exactly how a running bamboo grows.

If you look closely at the photo above you will see how the rhizones have spread in a straight line toward the open space. Every 4 - 6 inches a shoot has begun to reach upward, looking for light. Since the soil is so dense and lacking in nutrients in this location, the shoots are relatively short - less than 4 feet tall while only a few feet away, where the ground has been enriched with soil amendments, the same plants have stretched upwards of 15 feet.
