What is so special about redwood trees?
Redwoods create the strength to withstand powerful winds and floods by extending their roots outwards, up to 100 feet wide from the trunk, and living in groves where their roots can intertwine. A redwood can't grow to be the tallest tree on earth alone.
Why do Sequoias grow so big?
So how did these trees get so big and tall? We don't know for sure, but some scientists believe it has to do with the climate in which they grow. Sequoias benefit from Californa's often prodigious snowpack, which seeps into the ground, constantly providing water to the roots of the trees.
Why do redwood trees only grow in California?
Though they once thrived throughout much of the Northern Hemisphere, today redwoods are only found on the coast from central California through southern Oregon. Redwoods, however, get their water from rain rather than snowmelt, and therefore require consistent rainfall throughout the year.
Related Question Why are redwoods so large?
Why is it so quiet in the redwoods?
The bark itself has “tannins” which insulates the redwood, especially further up the tree. Why is it so quiet in the grove? Because the grove is so well shaded few plants can grow which would offer food and shelter for animals.

Redwoods have been around for about 240 million years, compared to about 200,000 years for “modern” humans.
How can a sequoia tree live for 3200 years?
Giant sequoia can thrive in a world of frequent fires. The bark of a monarch can be up to two feet thick, insulating them from fire damage. It's also rich with tannins that help the trees resist pests and disease, making giant sequoia resilient and long lived—the oldest known giant sequoia lived to be 3,200 years old.

Why do sequoias only grow in California?
Narrow Range. 1. Giant sequoias have very specific climate requirements, so specific that they grow naturally only in a narrow 260-mile strip of mixed conifer forest on the western slopes of the Sierra Nevada mountains, primarily between 5,000 and 7,000 feet in elevation.
Do redwoods have invasive roots?
The roots of a redwood tree can extend out between 6 and 12 feet below the ground. If you plant your redwood tree near a driveway, walkway, patio, deck, or even your home's foundation, the roots will eventually grow out and up, potentially damaging various surfaces and structures around your home.
Can I plant a redwood in my backyard?
Redwoods are best-suited to large properties, but can work in an average size backyard if you keep certain cautions in mind when planting. The first rule of thumb is to plant them at least 30 feet from the house, septic fields, water lines or drain lines -- the farther, the better.

Do redwood trees fall over?
“Redwoods have had a lot of root loss during the drought. If individually placed, they can fall over.” All it takes is a strong gust of wind and soil saturation for some massive evergreen trees to be uprooted, he noted. These evergreen trees retain their foliage year-round and can become top heavy.

What makes redwood red?
Redwoods get their common name from their bark and heartwood, the reddish-brown color of which stems from high tannin levels. Other chemicals found in the leaves, branches and bark give these trees a remarkable resistance to fungal disease and insect infestation.

Can I plant a redwood tree?
Redwood trees can tolerate temperatures that drop below freezing as they do in their natural habitat, but they need root protection as they would in the forest. Plant your redwood tree in the ground after one to two years, or once it has reached about 5 to 6 feet in height.

The new window in the forest canopy admits all-nourishing sunlight for surrounding trees, and the fallen log opens new homes for wildlife (including lichen, insects, and more), expanding the forest food chain and bolstering biodiversity.
What happens if you top a redwood tree?
Tree topping Redwood trees grow really tall. Wounds from large topping cuts can become a point of decay, which can cause hollows, sometimes deep into the trunk of the tree.
