Observation of coast redwood bare roote seedlings
In the past, there has been very little interest in the coast redwood as a timber species outside it's natural range. Because of its sprouting characteristic, there has been very little need for seedlings for commercial planting. We at H-H Forest Tree Nursery Inc. have been growing bare root coast redwood seedlings for about seven (7) years. By observation and trial and error, our appreciation of this species has really increased. While germination of the seed is generally low, there are so many seeds per pound that this is no big problem in seeding. Even though the native range of this species is along the coast, there is a certain amount of winter dormancy and we naked stratify for 30 days. We sow in an open trench which is approximately one half (1/2) inch deep and cover with perlite approximately one eight (1/8) inch deep. We sow on ground that is fumigated with four hundred (400) lbs./ac. Methyl Bromide then fertilize with nine hundred (900) lbs. 16-20-0 to the acre. We tried a field test which was not fumigated and it was a complete disaster. We usually sow two (2) or three (3) weeks later than our sowing date for Douglas-fir. As our target seedling size is twelve (12) to eighteen (18) inches high, we have found that an early seedling date results in twenty four (24) to thirty six (36) inches high seedlings.
