Q.how do i keep my pomegranate tree from dying this winter
It has survived one winter but barely and I did know it needed to be covered. How do I cover it so it won’t die?

You're looking for information on protecting your tree from damage...if it were dead, it wouldn't need to be protected. On that subject, here are a couple of articles: https://www.gardeningknowhow.com/edible/fruits/pomegranate/growing-pomegranate-tree-seeds.htm
