Never tried before. I've tried to grow my own slips from sweet potatoes, but just ended up with a shriveled rotten stinky mess.
I found some plants in the local garden centre, so bought one and popped it onto a large pot.
I will feed it once a week and keep it watered. I've no idea what I'm doing!
When I met Bob flowerdew many years ago, he recommended a greenhouse and said it was a climber, so not having a greenhouse I never realy bothered again. Now I've found out that some grow it as ground cover, and the leaves are edible.
So, I'm just going to see what happens. The pot will sit on a makeshift column, and allowed to trail, rather than treated as a vine climber.
We'll see what happens. Wish me luck! It wasn't a cheap plant.
