I was very excited to have started some sweet potatoes from shoots that took almost a year to grow on a store bought sweet potato. I rooted the shoots then transplanted into 3 very big pots. Two were eventually planted in the garden and despite a cool Alberta summer with very little rain I harvested about a dozen, from 2 or 3 quite nice sized to a fewer smaller ones. The plant in the big pot did very well also(put in greenhouse as it was a very cool fall as well) and a got about another 6 ranging in size from as long as my hand and about 2/3 as wide to some medium and a couple smaller. All were very tastey with thin edible skin(unlike the hard ineatable of the store bought) Ive since eaten all but the biggest which Ive cut in half, and put in water held up with tooth picks, which Im trying to shoot. Does anyone have any advice for starting shoots from store bought sweet potatoes or yams. Was I supposed to cut it in half(read that somewhere) as the prior store bought one wasnt but took a year to shoot???Any advice would be great!!
