The ease of propagating redwood vegetatively insures that any genetic variation in growth rate or cold hardiness which is discovered in provenance experiments, or bred in tree improvement programs, can be used to its full extent in plantations. These are vigorous 20 cm plants grown in containers for 6 months after rooting. For those with phytosanitary restrictions, unrooted cuttings sterilized in NaOCl are available at a cost of US cents 25 each, and tissue culture plantlets can be produced on request.
