Anyone have experience with Spruce pine (Pinus glabra)

I have a couple of Spruce pine in pots that are getting close to needing root trimming and i read somewhere they were very sensitive. Anyone grow this species? thanks

Spruce pine have a very limited range in the SE USA. You find isolated trees mixed in with hardwoods in low country and coastal forests; only occasionally do you find them in with other pines. They grow in clayey soils, but in fairly moist habitats. I've only tried one -- in my early days with bonsai -- and had no luck with it. I put that down to inexperience, however.

Based on where it is found, I can think of no reason for it to be any more root sensitive than any other pine. Someone in the Tallahassee (Fla) Bonsai Society had a very successful, large spruce pine bonsai that was, last I heard, doing well.

Are they in bonsai pots? If so, trimming is all they'll need; they've already had the major work done. If they're in nursery or other larger pots, you always want to be cautious on your first major root pruning. I'd aim for a larger-than-optimal pot for their first repotting.

Good luck, and I'd like to see pictures. With their smooth, gray bark and relatively short needles, these could be an unusual native bonsai.
