Growing a Sweet Potato Vine

February 17, 2017

Plastic Wrapped Sweet Potato Grew RootsMy plastic covered sweet potato was kept a little long and began to grow roots. I was happy to see this because it saves me time on the rooting process.


I placed three plastic toothpicks, like a tri-pod, to hold the potato. I placed the potato in the container and filled the container, with water, about an inch above the roots. I put my plant-to-be in a shady area in my kitchen.

I am happy I will have a sweet potato plant soon, their ivy-like leaves are beautiful. I believe they are related to morning glories. Here is a photo of the sweet potato next to a poinsettia I bought at the grocery store for fifty cents. Spring will be here soon!

I remember my mom growing sweet potato vines (as house plants) in a mason jar. How do you do it? I'd love to know. Can they remain in the water with some marbles in the bottom, or do they need to be planted? What type of light do they need? If I need to plant them, what do I keep the moisture level at for the soil?

I can't remember which end of the sweet potatoe to place in water to root it?

You put the end that is "pointed" down in the water in the jar. You can grow these in your kitchen window or anywhere else in your home, where there is natural sunlight. Once you put the potato down in the jar, only about half of the potato should be in the water. You don't ever have to plant these. From what I could tell, they could live indefinitely in the jar.


I hope this helps.

My sweet potato in the jar keeps getting moldy. I just moved it to a window that gets more direct light, but does anyone have another suggestion?

the first thing you do is you get a jar and fill it with water(make sure you leave an inch without water).then insert the root end in the jar make sure that the end was in the water

I tried to grow a vine from a sweet potato, and it only rooted a little, my sister told me that my mom use to cut one end off, but do you put the cut in down in the water or up out of the water? I didn't cut an end off and the potato rotted!""

I tried the sweet potato in the mason jar thing. I used the tooth picks and changed the water every other day and kept it in a sunny window.


But after a week the part that was immersed in water rotted! What did I do wrong? Dana in Pa

I'm trying to grow an Okinawan sweet potato. I soaked the long part of the potato. That part started to rot. So I cut the rotted part off and turned it around.

So can anybody tell me if that is right or wrong? Anyone in Hawaii?

You should put the pointed end of the potato into the water. Let about 1/3 of the potato stick out the top of the jar three or four toothpicks.


Sunny warm window or on top of the fridge. Add water as needed. Should be good to grow! Very easy plant and pretty, too.

I think success/failure depends a lot on how long the potato was in cold storage before you bought it. So try again, after you ask your friendly produce manager!

Stick a toothpick on each side so the bottom tip is in water. It will get sprouts everywhere. Be sure you put it in a place, or window for light. Once it starts growing it is nearly impossble to move. Mine I have just added water, but 2 drops of mirale grow probably wouldn't hurt.

After my sweet potato vine has long vines, can I plant it in soil after taking it from the water. How? Do I plant the entire potato?

Will this kill off the vine it already has produced? And this won't produce potatoes will it?

I would coat the roots in rooting hormone before I put it in the ground.

Perk up that bare kitchen window with a sweet potato vine. Place a sweet potato in a vase or glass, holding it up with three toothpicks so it doesn't fall to the bottom of the vase.
