I have small sprouts of redwood (sequoia), redbud, and two types of tall arborvitae. Should I pot them up in like one or two gallon nursery pots? My husband thinks I should just plant therm "where I'm going to plant them." Of course, I don't know where I want everything to go yet and I think they should be a bit bigger before being sent out on their own. I also will probably give some away to family. How do you guys handle WS trees?
