I'm going to plant out some cherry toms in baskets this year.

After I've got the seedlings to come through, I plant them in individual pots, until they get to a height of around 6 inches?

At this stage, will they grow upwards by themselves?

When I transfer them to the hanging baskets, how do I train them over the edges? Are they vine-like? Will they just do this naturally, or do they need support?
