You can put three or four plants in one large, 16 inch diameter hanging basket. You need to use a good quality potting soil and keep them in the sun and don't let them dry out. Time to harvest varies with the size and age of plants you buy and the variety. For longer harvests, go with everbearers such as Tristar or Ozark Beauty. June-bearing varieties produce a lot of crop, but all at one time. Everbearers produce a smaller crop over a longer period of time.
