I fell to a temptation today - I bought 4 grape vine plants in pots. I guess I always wanted them and well... here they are. My question is when should I plant them? Can I keep them in pots through the winter ? Shall I plant now - Ive got right southern sunny spot ready. I cant tell the exact age of the plants but they have at least foot high stump with proper bark, and quite tasty fruits - ate most of them on my way back home .
I would welcome all advice. Thank you.
