Last summer I planted slips from my existing sweet potato varieties in my raised bed and planted slips from the new varieties in 30 gallon storage containers. The soil mix was more of a peat based potting soil with some vermiculite, perlite and compost. Part of the reason for the experiment was to see if the containers would produce and to reduce fighting tree root invasion that occurs in the raised beds. It was fairly successful since I harvested 54.7 lbs of sweet potatoes from 6 containers and 11.5 from the nearby paths and pots. Now all that is left are the taste tests. :)


Molokai Purple- 4 slips (2 per container) produced 9.6 lbs (5.8 lbs, 3.6 lbs)

Purple Delight - 4 slips (2 per container) produced 12.7 lbs (3.5 lbs, 9.2 lbs)

Tinto - 7-8 slips (3-4 per container) produced 32.4 lbs (19.3 lbs, 13.1 lbs)

Path/ Pot potatoes 11.5 lbs

In comparison I had 26.9 lb and 18 lbs in my raised beds which are about 3 x 7.5 ft.

It was much easier to harvest the containers and they did not become as infiltrated with roots. All containers and raised beds had earthworms and seemed to have good moisture levels. There were even a few frogs and a little snake hidden in the containers.
