Hydrangeas

Hi Folks, I have 3 hydrangea plants outside still in their pots that I haven't managed to plant out. Is it too late to plant them out (now that we are having frosts outside), would you rather over-winter them? If so, where and how? 
Any advice will be muchly appreciated.
Thanks, Daniela

If they are intended for the soil rather than pots it's best to get them in sooner rather than later as the roots will then have all winter to get settled in.  Just don't do it when the ground is frozen.   Plant them on a day when the pots aren't frozen and can watered well befor eplanting. 

Prepare the soil well with improvers such as well-rotted garden compost and/or manure and then plant them at the same depth as they were in the pots.  Tease out the roots abt so they don't keep going round in circles, water well and give them a mulch.

I agree with everything Obelixx has mentioned - and I would also add to this to give them plenty of space between each shrub as they do spread out a good few feet and don't take too long to grow large either.  When you have planted them and before mulching or watering them in firm down the soil around the shrubs with your feet - this helps to prevent wind rock which could cause the plants to move, then water well and give them a good mulch.
