Growing Sweet Potatoes

Hi, from the Canary Islands, Last year I planted sweet potatoes in pots, (presuming that sweet potatoes grew from sweet potatoes) obviously not the case, and sadly I threw away all the vines, as I had not researched the eating of sweet potatoes leaves, (which I have eaten on salads and in tortillas ever since I knew the leaves were edible. Sadly once again I have had lots of leaves, after planting the rooted vines that I took off sweet potatoes , they all had great roots, but after more than 120 days, the leaves have turned yellow (sadly cannot eat these) but normally this means the harvest is ready, well I was hoping....But no...Nothing, not one potatoes ..So I have resigned myself to keep purchasing the potatoes but grow lots of leaves, and enjoy them...Maybe one day ...I shall find a Potato...
Weather here ideal for growing and I have been careful not to overwater...but there were lots of roots in the soil but not one potato...Any extra advice would be very much appreciated...from a jobless Lady, who is trying to be as self sufficient as possible...

I have planted sweet potatoes since April 2020 and as at yesterday 13th October, no good tubers were seen but roots that have not developed. Only one or two tubers harvested on a ridge. So, I begin to wonder of the harvest time. I did not see the leaves turn green. Could be soil be the issue becos I am not in the North, but planted at the half a plot of my residence. Grateful advuse

i just dug my sweet potatoes her in Va. I told my wife I'm going to try cutting some vines that still have roots on them and put them in a bag and freeze them for next year. I wonder if they'll grow ? What do you think ?

It is early August in Northern Texas, and my sweet potato plant has large, healthy leaves and vines growing along the fence out of a small box in the backyard. However, I will be moving several hours South by car and will either have to transplant my plant in the car and replant it in our new home, or harvest them soon. Which is my best bet?

Although I haven't tried this yet, I've heard that you can plant regular potatoes in old tires, stacked atop one another & filled with dirt; to minimize space I would assume.
My question is, can sweet potatoes be planted this way as well?

I'm new at this. I halved a sweet potato and placed the exposed surface in a glass with water. They sprouted beautiful leafy green stems! The stems are bushy and maybe 6 inches long now. Did I wait too long to plant them in the soil? If I twist them off, I fear breaking the stem and roots. Can't I just carefully slice around each stem and try to not disturb the roots- planting the slip with a margin of original potato around it? Thanks!

I bought some sweet potato seeds from Amazon last year but when they arrived there were no instructions as to how to start seeds. Can you help me with instructions as it is time to get going this spring?

For curing Sweet Potatoes, remember that 80 degrees with high humidity is the ideal, but not a exact requirement. In order to store them in the cool you need to time your harvest to that time of the year that is cooling off in your region. Otherwise your are trying to cure them in 90-100 degree weather or if too late in the year, 30-50 degree weather. I harvest mine when the weather is starting to change in October (NE Louisiana), when some days are in the low to mid 80s. After you have dug them up, DO NOT wash them. This removes healthy bacteria and opens them up to fungus decay. Let them dry outside under a shed (out of the sun and rain) for several days. This helps get them dry. Then transfer them to a storage room or a room in your house that stays around 80 degrees or fluctuates in the 60-90 degree range (I keep mine in an outside storage room spread out on racks or on the floor). If you mist stack them, try not to stack them more than two deep, as their skin contact slows the drying process and promotes fungus growth. For humidity I keep a couple of five gallon buckets of water with wet towels around the edge of them or hung up above them. Saturate the towels every day. The evaporation will add humidity to the room. The curing process may take ten days or it may take 30 depending on your situation. When the skins are no longer easily scraped off, they are cured. By then the weather will be cooler and I keep them in the same storage room (with NO water or wet towels). My winters here are mild, but the temperature in my storage room varies from 75-30 degrees throughout the winter, and mine store fine for 6-8 months. I have repeated this process for many years. Remember, our ancestors grew and stored these potatoes with very little temperature and humidity control, and they did fine. Regarding the question of having great looking vines but few potatoes, first I would get a good soil test done, but as they were grown in a raised bed, too much Nitrogen may be the problem, as excess N will tend to put more growth into the vines than the roots. Same thing goes for peas. I hope this helps. Happy gardening.

We have 1/4 acre garden. It's a major amount of work. So we cut corners where we can to save time. I start sweet potatoes in March, 60 days ahead of planting. I pick out tubers from last years harvest, usually medium size, although this is a good way to use small ones that are still good. I stick 3 toothpicks around the sides and suspend the tubers vertically in a jar (like pints) of water, halfway in and halfway out of the water. In a few days, the tubers will start to sprout roots and slips. When the slips have 4 leaves, clip them off and put them in another jar of water 1/2 full. The slips will begin to grow roots, when the single roots start to have small branches on them, take them out of the water and plant them in dirt in a container. I use tapered slick "dixe" cups, because you do not need drainage holes (no mess) and the slick cups make getting the plants out easy. I reuse the cups as long as they aren't severely broken. For the last plants, I just plant the whole tuber. In the garden, I hill up two ridges 3 to 4 feet apart and as long as the number of plants. I usually plant 50 plants, each plant about 16" apart. Water well as needed, if you get twisted curly tubers, that usually means not enough water. I usually harvest in late September (SW Missouri) with a potato fork. After the weather turns cool, they don't grow much, and in October sometimes the mice have a tendency to munch on the tubers, then the garden snakes follow and munch on the mice, and then it makes for fun digging, but hey the snakes are doing their job. I really like the variety that I grow, I do not know what it is, my mom started growing it 30 years ago, after trying several different varieties, and we still got it. It's "best" characteristics is good size, high production, great taste, fine grain and the tubers grow underneath the original plant. Nothing more frustrating than digging taters that are all over the place. Production is usually 10-12, 5 gallon buckets. After harvest, I spread them out on the lawn and hose the dirt off them. I let them dry and put them into paper sacks and then into the big pantry in the game room. Winter temperatures there are probably in the 65-70 degree range. They keep until the following year, and then we start all over again.
