Hi Zoe (how do you put the 2 dots above the 'e'?)
Sorry I just saw this! And I think you're right, this being posted in something other than the 'Ask a question' forum means it won't generate an email alert. Don't like when I'm late like this, I'll have to remember that.
Well here we are past the growing season here in Connecticut, but I'm making note of replies for next spring. Today I even scoped out where I may put part of the garden in the ground. I may try a container or two on the deck, but as you said ideally plants will be in the ground.
I did bring in a parsley container a few weeks ago. It's been doing well enough, nothing like fresh, even from an indoor plant. I guess something like that will grow about the same as in the ground.
I'll have to set myself a reminder to 'Watch' this thread.
