Things do much better for me in clay pots...perhaps I tend to overwater...don't know, but I'm one of those who feel that plants can 'breathe better' in clay pots. Most plants are going to need larger than a 1 gallon if you're going to want to kep them in it for awhile. Clay pots from WM are always on my 'Birthday or Christmas wish list' and this last couple of years I bit the bullet and started buying more clay pots. I have a lot of plastic pots and use those now for growing veggies and strawberries and larger 5 gal size plants larger plants...etc.
