Aww that is a good item to plant - I also plant potatoes because it is so easy. I plan to try sweet potato again although I do not have a long period of sunny weather. The plant is beautiful with its heart shaped leaves of the plant with the running vines.
Yes! This was easy, I heard Irish is easier and more fruitful can't wait to try it.
Yes potatoes are easy - I think the name irish potatoes is used generically for all types of potatoes. However I think do not plant irish but different types of white potatoes. Like you I do not plant in the soil but in various types of containers and it works very well. Good luck with your endeavours.
