winter care of Euonymus

I assume you mean a Euonymous Green and Gold? These re pretty resilient shrubs and should survive a frost, however I'm not too sure where you are and what your climate zone is. What sort of temperatures do your frosty conditions get to. Wait til the weather warms up and give it a trim, a hard prune won't hurt at all.

I would sugget you pickax a hole in that frozen ground you have and plop the pot and plant in. Tamp the soil tight and mulch with leaves. Hopefully snow will add to the protection.

Even hardy plants such as Euonymus are not hardy when they are in pots. Think of a qt. of water left outside on a freezing night. The freezing will break the glass. In a container it crushes the roots. I hope I am explaining this okay ... I am looking at loosing thousands of plants because of lack of snow. If the snow comes, I am saved.

Forget about pruning, just get the guy buried or mulch up to the top with leaves. That is what I did to all my bonsai.

Prune what is left in the spring. Not now.
