Hi, I have plans to order 100 seeds of Sequoiadendron giganteum and 60 seeds of Pseudotsuga menziesii var. viridis. I live in Croatia, Europe and been wondering whether the climate here will be adequate for seed germination? I would store the seeds in refrigerator during winter. In spring I would sow them outside in a sunny location. What are the chances of germination? Any tips that would improve germ.rates? Thanx!
