I have a giant sequoia that I started from seed in general purpose potting soil some years ago (long before I had any idea what I was doing). I’ve hesitated from swapping out the soil on this one as I’ve heard bare-rooting can do some vicious things to this species. The tree is now 82cm tall and I’m eyeing it as a potential subject. But I really, really need to get it in something that drains better this next spring (I’m eyeing a pumice/grit mix). So, I wanted to poll some opinions on a pair of questions:
- Has anyone successfully changed out nursery soil/sub-optimal soil from a giant sequoia?
- How do you handle the difference in drainage when only bare rooting half of the root ball? Do you treat the old soil portion as a separate tree, on a separate watering schedule from the new soil to prevent from overwatering?
Many thanks for any insights!
