Need overwintering help for shrubs in pots

I have about 10 plants still in pots and need to overwinter them because I am unable to plant till next spring. I have Holly, red twig dogwood,lilac, cl. hydrangea, pyracantha, sand cherry. I don't have a garage or shed and am not sure how best to overwinter them. We do get quite cold int he winter I'm in NW Missouri. Appreciate any suggestions! We had two trees that were supposed to be removed for the planting areas and that didn't happen so I just can't plant yet.

Bunch them together in the most sheltered area available and put bark, sand or sawdust between and around the pots, to provide insulation.

first .... if you have good draining soil ... simply sink pots and all in one hole ... and loosely backfill ...

the key is .. GET THEM DORMANT ... AND KEEP THEM DORMANT ... [wish i had a dime for each time i typed that in the last few weeks ...]

if zone appropriate... temps are not important ...

NO SUN ON POTS... they can easily thaw roots.. which then refreeze ... etc.. more than once.. and the plant will die ...

and it wouldnt hurt to keep the plant out of blistering winter winds ...

can do any of the following:

north side of the house .... once frozen.. tip on side.. this avoids sun on pots.. and tipping in late dec avoids water accumulating in frozen soil ...

buy 3 bales of straw.. and place against house.. and circle with bales... reduces wind ... and sun on pot

or.. as above... dig hole in veggie garden.. and sink pots and all.. presuming you do NOT have clay soil ...

review the KEY ... and you will succeed.. no matter which option you take ...

it might be a great time to give them a thorough soaking ....

I agree, in zone 5, 'digging them in' as per Ken's instructions while more work is almost always successful.

The above ground insulating method has a spotty success in my zone for just about everything.

Thanks for all the great info. ok am searching out an area that will work. I'm trying to find less sun but not so windy. The south side of the house would be a better protected area from the bitter cold but it gets sun in the winter. I have tons of leaves I can use to cover the pots. I don't really have an area to dig to put all the pots in. I have a few days to find a good spot so I am looking.

I have better luck with mulching above ground than burying the pots as drainage is better. If you use the leaves, bag them while dry and use the bags; otherwise the leaves will pack down. Cold is fine for them - you want to avoid freeze thaw cycles, so keeping them out of the winter sun is most important.
