Silky Oak: December 2023 repotting by michaelruschena Posted on January 3, 2024January 3, 2024 Like my other seedlings, these have needed to come out of the planters for most of 2023. I finally act on that. They’ve grown since February, but not as much as I’d have hoped. 4 parts perlite, 4 parts pumice, 4 parts scoria, 1 part charcoal. And some slow release fertilizer. Into the sun to grow.
