Bonsai Training Information

Sequoia sempervirens
Costal Redwood, Californian Redwood

Native to California the Costal Redwood is prized for its wood which is light weight, and resistance to decay. With fragrant scale like leaves this giant is an extremely quick grower. Fully hardy in Britain, though they may lose their leaves in cold winters, with seemingly no detrimental effect on the tree. It thrives in Britain in the cooler moister western parts of the country. It is a long lived species with many specimens reportedly over 1000 years old.

Styles:

Formal upright, Informal Upright, Slanting, Twin-trunk

Location:

Outdoor

Position:

Direct sun for at least a portion of the day will be necessary for vitality. In the peak of summer a position that is shaded during the hottest hours will be helpful. Be careful when the temperatures get high.

Watering:

The Costal redwoods prefer constant moisture. Unlike most species which like to dry out between waterings this species prefers consistent moisture and does not tolerate any drought at all.



Feeding:

Feed every second week during the growing season. Use a balanced fertiliser.

Leaf and Branch Pruning:

A very vigorous tree, continually pruning is required throughout the year.

Re-potting & Growing Medium:

Every second year for older plants, every year for younger plants as they grow very fast and can get pot bound quickly. Repot in early spring or early autumn when weather is still warm. Use a fast draining soil 2 part Akadama, 2 part Pumice and 1 part Sphagnum Moss to help with moisture retention.

Wiring:

Bonsai shape is normally achieved with just clip and grow as it is a fast growing species, but wiring can be done if canopy correction are required during warmer months of late spring and summer. Don't leave wire on for too long as it will scar the bark.
