Redwood how fast do they grow
The oldest living redwood trees are between 2, and 2, years old. A mature redwood forest is composed of trees , years old on average. The trees in this redwood grove are approximately 65 years old. Coast redwoods can grow three to ten feet per year. Redwoods are among the fastest- growing trees on earth. After several decades of there being no restrictions on clear-cut logging, serious efforts in conservation started. The parks are protecting 38, acres of old forest.
Coast Redwood Water Needs According to a report in the journal Oecologia, redwoods use more than quarts of water each day in the summer and up to 40 percent of it is from the fog. These trees produce canopy roots on high branches that absorb fog water. Water regularly to keep the soil moist, not damp, and place the plant in an area with adequate sunlight. Once the sprouts have grown about 2 inches, they are ready for a new home. Transplant coast redwood trees individually or in a row spaced 7 to 20 feet apart in well-draining soil.
The Oldest Tree in the World It's not always easy to date a living tree, but most experts agree that a bristlecone pine tree Pinus longaeva in California's White Mountain range nicknamed Methuselah , is over 4, years old. Plant coastal redwoods at least 15 to 30 feet apart to give them plenty of room to grow ; crowded conditions can cause the trees to drop their lower branches. Average mature trees are from to feet high with diameters of 10 to 15 feet at 4 feet 8 inches above the ground.
Exceptional individuals sometimes reach a height of feet, a diameter of over 20 feet, and an age of approximately years. Redwood leaves are green, flat, and sharp-pointed. This tree grows at a fast rate, with height increases of more than 24" per year.

Sprouts develop their own root system and create circles of new trees around old stumps. These new trees are all genetic clones of the original tree and may have interconnected root systems which helps their stability.
Sprouts grow more quickly than seedlings, sometimes achieving heights of seven feet in a single growing season. Sprouting capacity decreases with size and age. Redwood grows in nearly pure stands as well as interspersed with other conifers and hardwoods. Pure stands of redwood are found only on the best sites; moist flat ground along rivers with gentle slope below 1, feet in elevation.
Redwood predominate in these locations because it is better adapted to flooding than other trees. Repeated flooding builds up the soil level at the base of trees. Redwood adapts by putting out new roots higher up in the soil while other trees are killed.
Coast redwood usually dominates when growing with other trees. Redwoods grow very quickly in full sunlight, often 18 inches in the first year, and 2 to 6 feet a year for the first 10 years. It can also grow faster than associated species in deep shade. Redwood is often found growing with Douglas-fir which can grow as quickly as redwood on many sites.
Other associated species include western hemlock, grand fir, and Sitka spruce. On drier slopes tan oak, madrone, maple, and California bay laurel grow along with the conifers.
Tan oak and Pacific madrone, like the coast redwood, often resprout when cut, and can reoccupy a site as quickly as redwood. Redwood is shade tolerant, meaning that it can survive at very low light levels. Small trees in the deep shade of the forest floor can survive for many years and then grow vigorously when events around them, such as logging or fire, increase the sunlight they receive.
Large trees and dense stocking combine to produce high yields. In open stands they can grow more than an inch in diameter per year. On industrial land, clearcutting is the preferred silvicultural system. Shelterwood, and selection cut are also used, though both are considered less economical because residual trees may be toppled by wind or damaged during logging, or may not grow well.
This increases their stability during strong winds and floods. Redwoods are naturally resistant to insects, fungi, and fire because they are high in tannin and do not produce resin or pitch. Their thick, reddish, pithy bark also provides protection and insulation for the tree. Even a downed tree can survive The blackened hollows you will see when you walk through the grove were caused by a fire in , and are a testament to the trees' remarkable ability to survive.
Redwood trees flower during the wet and rainy months of December and January. They produce cones that mature the next fall. Redwood cones are about an inch long and they produce tiny seeds, about the same size as a tomato seed. While each tree can produce , seeds annually, the germination rate is very low.
