Hi alsers, how do you grow Sweet Potato? Do you just plant the tuber direct into the ground like common potato? What spacing, depth, support, manure etc is required? Cheers porgey.December 10, 2010 at 6:59 pm #484723
Depending on how many you want, but I use both small tubers and slips.
I have a stack of small SP to go in and there is one large one with shoots on that I will wait till they are a bit bigger then I’ll pop them in the ground. I don’t plant in rows as they tend to send roots down at the leaf joins and grow more SP, I don’t support them as I use them as a ground cover which helps supress the weeds a little bit. I set aside an area 4m X 3m and they fill it in no time… but I haven’t got them in yet as I need to weed the area, too much rain and the weeds take over.December 10, 2010 at 7:01 pm #484724
I found a some old thread about it. check them out here:December 10, 2010 at 7:08 pm #484725
There are many theories put forward every few months, and they all work, however if you are in an area where they do well the best and fastest way to fruit is to get some runners from someone, cut to about 30cm, bury horizontal with one end out a bit, keep up the water, they need lots of space and let go, they hate cold weather.
Ive found if you have ok soil they dont need too much fertiliser and can handle quite hard ground
If your stupid market ones sprout in the cupboard, plant the shoots when they get some length to them or dice up the tuber.
Try some different types other than the ho hum orange onesDecember 10, 2010 at 7:22 pm #484726
Thanks for your replies. I have three tubers, do I just plant them like normal potatoes?December 11, 2010 at 5:28 am #484727
My first attempt at growing sweet potato a few years ago yielded over 14kgs of potatoes. I just cut then end of a sweet potato and put it in a chinese take away container half full of water on the kitchen windowsill and I just kept the water up constantly and it went beserk. Once the shoots were about 5-6 inches or 13-16 cms long I went and planted it out the back in an area of grey sand that is about 12 foot by 4 foot. I planted the end of the potato and the shoots and I only left about a centimetre of the shoot sticking out of the ground. That was all I planted and when I dug up the area about 9 months later to plant something else in there, I discovered tonnes of potatoes…well 14 kgs worth anyway. I felt like a right twit too because I thought it had all died as the greenery had all died off so I figured I’d screwed it up. I had to dig down almost a metre to get it all out as well. I have to admit i was pretty patchy with the watering too after the first couple of weeks. They didn’t get watered for about a week once as the retic had a hernia and I refused to use the tap water on the garden. So in my case treating them mean kept them keen….not sure it would work every time though. Good luck.December 11, 2010 at 2:12 pm #484728
I planted some sweet potatoes a few months ago. I put two plants in about 30cm apart. I did water them for a while to get them going but now I just ignore them.
They produce more tubers when mulched but unlike regular potatoes you don’t need to keep piling it up.
Sweet potatoes are like a ground cover and will spread horizontally.
One of our old cattle dogs loved sweet potato. Every once in a while we’d discover her in the middle of the sweet potato patch, munching away. She’d worked out she could just dig them up whenever she wanted to! :laugh:December 11, 2010 at 8:10 pm #484729
first up areteh tubers viable? teh ones from the bigger stupid markets can be treated so as no to sprout, if you see a budding one on the shelf buy it.
i like those red/purple skinned ones sold in most small f&v shops they usually aren’t treated.
anyhow here is how we do it:
