First thing I would do is start removing that nursery soil mix and if the bark is starting to split and flake off and the buds are starting to swell, it is a good time to do so. I have had success with smaller nursery material like this by gently teasing off soil from all sides with minimal tearing and pulling. The roots are very fine so keep them misted frequently. Avoid wetting the leaves. Incorporate a pumice-lava mix, I’ve had success at about 2:1. You don’t have to totally bare root it although I have with small starts. Best to leave a portion of the original soil for removal at the next repot. Manzanita feeder roots are very fine and delicate. Keep it moist to allow regrowth of those fine feeders. They die if dry. Leave the top alone. You won’t be styling any yet. After a repot I shade and shelter for a couple of weeks, keeping the soil moist. Did I mention avoid wetting the leaves?
