You are in a little bit of a tizz! Presuming you are in the UK and these plants have been grown from autumn sown seed, it's time they were planted out now.
Being deep rooted, they will do best in deeply dug & fertilized open ground. They need to removed from their pots, retaining as much compost as possible to avoid root disturbance......this doesn't apply to biodegradable pots of course, these are planted in the ground, complete with plants.
Some people do prefer to use large pots or containers for their final planting, but this is a second best IMHO.
They will need supports of around 8 ft and some kind of wind protection in the early weeks.....oh, and keep an eye open for slugs 'n snails.
Hope that helps.
