can someone give me some ideas on how soon I can start my containers--I think it would be ok to start them now inside, but am not sure what would be best to start with
Hmmm. I mostly start vegetables in side, and in February I begin the slow starters like peppers and parsley. For flowers I'd start things like impatiens, geraniums and coleous (sp?). You can also start pot marigold indoors this early, as they can handle moving outside when it's a bit cooler. Sweet peas, too, can be started inside, but I find they are stronger if I start them outside. I start any cool weather veg, too, as I can put them out as soon as it warms up enough that they won't die. (Marjorie Harris recommends 8 nights in a row not cooler than 8 degrees for a number of plants).
I confess that a lot of my plants have been experimental, and as long as I take care to harden everyone off and provide protection during a cold night (either bringing them back in, tucking them inside the greenhouse, covering them with a cloche or whatever I have to hand, or placing them next to a south wall) my plants have been really forgiving.
When to start your containers in doors largely depends on what you are growing. If you are growing from seed they usually specify on the seed pack when to start. I started my Canna lilies about 3 weeks ago. What are you growing?
