Raspberries can be grown in half barrels or 5-gallon containers. "Container Gardening for Dummies" recommends placing three to five plants in a half barrel. You may only want to place one or two plants in a 5-gallon container. You could also place raspberry plants in a hanging basket if you like.
The Container Gardening Expert recommends keeping raspberry plants in a cool place. Even so, the plants should not be exposed to frost. Raspberry vines need sunlight in order to bear fruit, so a spot on your patio with filtered sunlight in the afternoon can be an ideal area for these pots.
Make sure there are holes in the bottom of your container to allow for adequate drainage. If possible, set the pot on a couple of wooden blocks to facilitate drainage. Raspberry plants do not like to be extremely wet, so take care not to soak the roots when watering them.
