Query About a Holly

in Plants
Having just read the thread about another tree species , thought I would check on what to do next.
When we moved my variegated holly was too big to come with us so took some cuttings. Year one five in a pot in the greenhouse three died. Year two these two put on a little growth so moved them into own pots, nearly loosing the little one, and later in the year they went outside. Over winter buried pots in a garden tub hoping to keep the roots frost free without disturbing them. This year in spring when pots lifted roots showing, so planted into pots in picture. Question is as now too big to bury pots will they be ok to leave over winter outside in these pots or should I put them back in greenhouse. Sorry it's so long a read but these are special irreplaceable plants to me.

But if you are concerned with harsh frost on the roots, you can sink them half into gravel or sand in a semi deep tray, or wrap the pots in bubble wrap. When my Olive shrubs were younger, I used place them into a slightly larger pot and squash/pack in loads of bath sponges into the base and in-between the pots to keep them insulated.
