If you could be bothered to plant them now, it would be easier in the long run, I think.
It will be fine in the pot, in a sheltered spot under a hedge, or instance, for the winter, Rob.
When planting, they are not very fussy as to soil. You should dig them into the ground, in an open, sunny spot, about one to two feet ( 30 to 60 cms) away from whatever you want the Trop. to scramble up. Planting them too close to the foot of your intended host plant or fence etc does not seem too successful - it is better to have them our in the sun and able to get some rain and they will soon find their upward route.
