Thank you for the sequoia website. I read the whole thing and it gives very good instructions on repotting under the bonsai sequoia section. The directions are very specific, so I'd recommend going to the site and reading them. Apparently sequoias have very fragile feeder roots. I learned a lot from reading that site! Thank you for the photos of the slate also. I will try that when I move since I have to dig up the trees anyway. On another note, one of my friends apparently has a sequoia photo on the sequoia website, which was fun to see, so ill have to ask him if he sells them.
