Hi everyone There's three questions here. Am I allowed to confuse things by putting them together? I keep thinking about different carbohydrates I can grow, one that springs to mind is sweet potato, either white or orange fleshed. Does anyone have experience with this? Do you get them to climb or scramble? Do they go mad and take over the garden? And if so, can you get rid of them once they've got hold? It's the same query about Jerusalem artichoke: do they go mad? Should they be contained in some way? The ginger thing: how do I get ginger to shoot/root from a bit I buy in a greengrocer's? What temperatures does it require? Might it grow in a protected spot on a patio in temperate areas? Has anyone had any success with this? (I'm sure this question seems weird to you tropical folk). Thanks so much for your help!
