What is the best planting distance for begonias? Do they do best when crammed together, like fairly tightly packed in a basket? In which case, how many to a basket, say 14" diam? Or what distance between them if in a container? I find the advice on this from most suppliers generally seems poor or ambiguous, or not particularly helpful or detailed enough. Are they better planted with some space between them so that air can circulate, and will doing so help to reduce the chance of mildew infections occurring? Thompson and Morgan recommend in their leaflets John Innes no 2 for growing them in. Do other GOY users find they do just as well in multipurpose?
