Noob, need help

Hi there,

I had a thread a while ago asking about starting up my peppers but I thought I would ask in the right section to continue the discussion - I was away for some days and bam, plants out of control all of a sudden.

Purple super hots in the centre, mini Jalepenos on the outsides and in between on each side are Red Fire.

I gleaned from the other thread that I'll probably have to move a couple plants out to a planter or new Aerogarden.

Will these be able to bear fruit at all in this garden?   Are they just plain too tall for this?  How do I prune this and should I prune it now?

Any help is appreciated.

Thanks
