If they're scraggly due to being in the small paks too long, they may not do well at all, but it's worth a try. Cut the plants back to a few nodes (where leaves join the stem.) New shoots will appear at the nodes. Plant them at the same depth they are growing at now, or up to the first set of leaves. Give them a bit of fertilizer. Good luck.

I wouldn't cut them back now....you have a limited amount of time for them to grow....so don't set them back any more weeks to bloom.
Just ruffle up the root ball and plant and water well....and keep watered.....they will take off very quickly!
