Taxonomic Information

Appearance

Sequoias are some of the largest trees in the world, with the giant sequoia reaching up to 311 feet tall and over 52,500 cubic feet in volume. The coast redwood can grow even taller, reaching up to 379 feet tall. Sequoias have reddish-brown bark, with a fibrous texture that can be up to three feet thick on older trees. The leaves of the sequoia are needle-like, and can grow up to three-quarters of an inch long.

Care Guide

Sequoias require plenty of water, especially during the summer months. Regular fertilization is also important, with a balanced fertilizer applied in the spring and fall. Sequoias prefer well-draining soil, and are typically grown in full sun. They are hardy in USDA zones 6-9.

Common Pests & Diseases

Sequoias are susceptible to a number of pests and diseases, including spider mites, aphids, and scales. These can be treated with insecticidal soap or neem oil. Fungal diseases such as root rot and canker can also be a problem, and can be treated with a fungicide.

Habitat

Sequoias are native to California and Oregon, and are typically found in areas with high rainfall and moderate temperatures. They can grow in a variety of soil types, from sandy to clay-like, as long as the soil is well-draining.
