I had a few red potatoes that started sprouting to the point that they had a lot of dense green leaves sprouting. I cut a couple of them up & let them heal over for a few days, and a couple I left whole. These were from the grocery store.I used these mainly because I had them and had nothing to lose and because I can not find seed potatoes here in Miami and when I’ve wanted tried to find some online, I’ve never been able to get the varieties I’ve wanted shipped to me when I’ve needed them. We have a different planting schedule from most of the rest of the US.
That said, I’ve generally had good results from my sprouted store bought potatoes. They don’t taste anything like the ones I originally purchased (soooo much better). Unfortunately, my last batch of potatoes died in the last (rare) frost we had, so I was happy to plant these. I did get some potatoes from the potatoe plants that were killed, but not what I would have had if they were allowed to grow more.Some were medium size, but most were small.I’m wondering if I should save them for seed potatoes. They may be too small, since a lot of them are large marble size.
I am trying something new this year. I am growing the potatoes in large black plastic contractors bags. I am growing them in a mixture of organic potting soil and compost. I also added in some organic fertilizer for acid loving plants, since I think I read here on folia that they prefer a slightly acidic environment. The thing that is different this year is that I’m growing them in the bags. Previously, I have grown them in my raised beds surrounded by chicken wire into which I would add compost and seaweed as the plants grew. The only problem was that the wire made it hard to reach down to the plants to add the layers of seawed, without risking covering the plants completely. So I changed to planting in large Rubbermaid storage containers. It seemed to be going well, but it seemed like the plants had out grown them and I was going to have to put some sort of border up so that I could keep adding seaweed to possibly four feet high, but the frost ended things before I had a chance to get that far along.
I think that the plastic bag may work well, because they are really big and you can roll them down to maybe a foot high when you start out and then unroll it as your plant grows and you add your straw, seaweed, compost, etc. I was a little concerned about the bag deteriorating, but them I remembered that I have stored bags full of seaweed or sawdust for long periods of time with no problems.
I’m going to be planting some sprouted Yukon Golds I have, soon (regular store bought potatoes again) and I havent decided if I’m going to plant them in these bags or not, but I do know that I’m not going to be layering anything onto them, because that doesn’t seem to work with them.
If anyone in South Florida knows where to buy seed potatoes, please let me know.
