Last year was my first year with a lotus. I put in down into the pond. Then this year, it was so happy there I ended up leaving it. This year, I have a baby doll lotus and I'm going to sit it in the pond as well.
I'm in zone 6a, but sometime we do have harsh winters. This way I don't have to worry if it dose get below freezing. I do plan on moving this one back out of the pond in the spring.
