Pots for Plants: *Which size & shape* is the *best* pot for which plant . . . ?

hi there, well terracotta pots dry out quicker then plastic pots so they will be okay for cactus etc. put some little stones or gravel in the bottom of the pot for about 4cm or 1 and a half inches, deep this will allow a little drainage for the plants. Really the shape of the pot doesnt matter as the last person answered its just for looks, I say the only thing that is good about the plastic pots its easy to remove plants when they get bigger, if the top of the new pots is smaller then the base then its hard to remove plants when they grow bigger, I hope this helps a little, by the way sandy soil definately better for cactus and with the succulents use the sand buy add a little clay soil to it have a happy planting day :)
