Sweet Potato Experiment Update (2017)


Before I get started, here is the link back to the first post on the Sweet Potatoes. I did try this a few years ago, and I never got to the part of putting them outside. I did have some really beautiful flowers in my kitchen window though. If you didn’t know, Sweet Potatoes are related to Morning Glories and are not part of the Nightshade family like regular potatoes. So in all actuality, I may only be able to produce pretty little flowers and tiny little tubers not worth all this effort. That is the beauty of an experiment. These are FAR outside my zone, but I am banking on the heat of my patio to hopefully get a little harvest. I don’t have aspirations of becoming a sweet potato farmer, this is just a fun little thing to try out.


I left the last post at “wait for sprouts to arrive”…

Well boy did they ever. Within a week, I had some sprouts that were almost 6 inches tall. Keep in mind that these are vines, so they will grow fast.


Once these sprouts get a decent size, gently snap them off. This takes a little bit of the tuber away with it. (Just be gentle and don’t be alarmed. It is just a sweet potato and we are just experimenting. The fun is in the learning and its ok to screw up.)  Leave the smaller sprouts on the tuber to develop some more.


Take the sprouts you removed, and snip off their lower leaves with scissors or a pinch of your nails. Put these in a separate jar. Soon we will see some little roots sprouting off the stem.


Now the trick will be to keep them growing slowly until we can get them into their final home. I’ll update again at the next steps. Or if anything exciting happens.

A few points to remember:

  • Keep the jars topped up with water. As the sprouts start growing more vigorously, the water will go down faster. Just keep an eye on it and don’t let it dry out. I have to top the tuber jar up every couple days now because of the amount of sprouts/roots happening. As the slips start producing more roots, that jar will need water added more frequently as well.
  • If you notice the water is getting smelly, growing algae, or turning a weird colour, dump it out and add some fresh water.
  • I don’t know if I clarified to put these in a sunny window or not. If I didn’t then I am now… Keep both jars in a sunny window. Plants need light. 😉
