AMERICAN SWAMP CYPRESS
The Bald Cypress needs a lot of light and warmth and should therefore be placed in full sun during the growing season. In a warm climate, it can be kept outside all year round. In areas, with colder winters the Bald Cypress must be protected against very low temperatures as it tolerates hardly any frost when it is planted in a container.
During the summer the Bald Cypress needs a lot of water and if you can't water it often enough during the day it can be a good idea to put the bonsai pot into a shallow bowl filled with water. In winter, when the leaves have fallen, the Bald Cypress needs less water but should never dry out.
Use liquid fertilizer from spring to autumn every week or every two weeks regarding the dosage instructions. During the growing season, solid organic fertilizer can also be applied.
Pruning and wiring
New shoots can best be shortened when they begin to produce lateral ramification. If they are pruned too early, they often die back in autumn. In autumn or early spring branches can be pruned. The Bald Cypress tends to produce a lot of new buds on the trunk, branches, and forks. All those buds which are not useful for the design of the tree should be removed at an early stage. Young branches and twigs can easily be wired and shaped, older ones become stiff and brittle. Lowering the branches is done best by using guy wires.
Bald Cypresses have strong root growth and the roots become thick very quickly. They are not hard, though, and can be pruned easily. Younger trees should be repotted every two years with root pruning, especially if the growing rootball pushes itself upward from the pot. Older trees can be repotted every three to five years.
The Bald Cypress can be propagated by seeds and cuttings quite easily.
