How to Care for Redwood Trees. The largest redwood, the General Sherman Tree, stands 273 feet tall, has a circumference of 102 feet, and weighs an amazing 12 million pounds. It is the largest living single organism on the planet. These trees can live to be over 2,000 years old. Redwoods are native to the coast of southern Oregon and central California.
Plant your redwood trees in good soil. The tree needs to be planted in acidic, loamy, moist, sandy, well-drained but wet clay soils.
Site the tree in full sun. Fast growing trees such as redwoods need to be in full sun, so make sure before you plant it that it will receive full sun.
Locate your tree next to your lawn. Redwood trees require lots of water. You have to be careful, if you do though, because in 10 to 20 years the tree may take over your yard. Redwood trees usually grow to between 70 and 100 feet tall with a spread of up to 25 feet wide. Some even reach heights of up to 120 feet.
Watch the leaves of the redwood as it grows. The leaves should be bright green with a fine, feathery appearance. If the leaves starts to turn brown or sickly, should test the soil to see if it offers the right acidity, and make sure it is getting enough water. If the soil test shows the balance is off, speak to an arborist for advice on how to amend the soil.
