I recently bought a sampler online that contains three saplings. One each of Giant Sequoia, Dawn Redwood, and a Coastal Redwood. With great looking bonsai as the end goal, I’m curious how you guys would start the process. Should I make wood grow boxes, plant them in the ground, use a colander or pond basket? Also what soil type? Straight to 1:1:1 or a mix of potting soil and pumice? The trunks are smaller than a pencil at this point. I’m thinking root development would be step #1. This is my first year with bonsai.
Thanks for the help.
