Okay guys quick background, my normal routine is the barrel bog gets mulched over with dead leaves, topped with mesh and survives fine here in zone 7A. The smaller pots, six inchers and deep or 10-12 inchers and shallow get buried in shallow graves that are lined with the mulch (bottom and sides), their tops left 1" or so above the ground level and topped with leaf mulch once it gets cold.
This year I have a tall 12" pot. I can't decide if I should:
1. Bury it like the smaller pots or
2. Just place it in an empty 20" pot and fill in the space between them on the bottom and sides with mulch, leaves, etc to provide some insulation and then mulch and cover it the way i do the barrel.
Any suggestions? It's a collection of alata, rubra, minor, leuko and some hybrids I picked up this summer.
