So I'll try to keep this shorter than longer. Bought a dwarf yaupon holly near the end of last season. Beautiful trunk, tiny leaves. It was a project I was looking forward to. I buried the nursery pot in the ground like most of the rest of my plants. It even looked fine most of the winter, being how bad it was. Over the last few weeks as we are starting to leaf out I noticed how my boxwoods took varying degrees of wind burn. Then I noticed the holly didn't look so good. Then I noticed that if I brushed it all the leaves fell off. The were all purple/brown with only a few green leaves toward the bottom of the plant. Wondering what would have done it so wrong I start searching to find that this is a zone 7 plant that just went through a true zone 6 winter. I don't make a habit of doing that and would have protected the thing better had I realized. It wasn't even expensive, just had a lot of potential. Sooooo...what do I do with it? Leave it alone except water till I see what comes back? There are live leaves so it's not entirely dead yet. I had wanted to reduce the roots some this year and take out several branches to help choose the trunk. I shouldn't touch the roots due to it's trauma, correct? And removing branches could remove buds it's trying to open but will the wounds be more shocking and therefore detrimental? I hadn't put really any work into this tree yet but it had such a nice trunk. I hope I can save something. Any suggestions appreciated.
