Redwoods and sequoias. Advice for saplings?
 

I just bought California redwood and giant sequoia saplings. I live in
southern California. It's somewhat chilly here right now, around 30's and
40's at night. I know it'll take years before I can even think of shaping it
or trimming it, but right now I just want to them to grow. Anybody have some
advice? I don't know what's the best way to care for them, so any advice
would be appreciated =)
