This article cites a study, conducted by researcher George Koch and his colleagues, which states that trees stop growing when their highest leaves start dying of thirst. A new study in statuesque redwoods finds that the trees stop growing when their highest leaves start dying of thirst. Water rises through a simple process, as water evaporates from leaves, tension within the trees pipes pulls water from the roots to replenish what's been lost. But after a certain height, the force of gravity becomes too much, and this flow peters out.

Focuses on the biochemical factors that limit the height of trees. Use of the capillary action of water for water to get to its leaves; Role of the xylem in carrying water from roots up to the leaves; Evidence suggesting that the giant redwoods are as tall as water will let them be.

This article focuses on the collection of bonsai maintained by Indianapolis Bonsai Club President Paul Weishaar. Weishaar and his fellow bonsai aficionados — some 100 in the Indianapolis area alone — have spent many hours over many decades watering, trimming and wiring their tiny trees to produce replicas of their ancient, life-sized counterparts. Woody, small-leafed species — dwarf junipers, Japanese maples, pines and even redwoods — work best, their branches painstakingly tended to suit rigidly defined styles.
