Why Do Trees Grow So Big?

Flowers and trees grow during the spring and summer. In the fall and winter, flowers dry up, but the trees continue to grow slowly. Trees usually live longer than people. But unlike people, who stop growing when they become adults, trees grow as long as they live. That is why they grow so large. Tree growth occurs at the same time above and below ground. Some redwood trees in the United States are more than 100 meters in height and a full 10 meters in diameter. Even though redwoods originally sprouted from a single seed, these trees have gradually grown to giant size over a period of several thousand years. Trees keep getting bigger as long as they live.
