i had an orange tree. didn't get it wrapped in time. the leaves r all dried up. but still hoping. be eager to see what eveyone has to say. joyce

The graft top is the tree you bought. The graft bottom is a root stock tree that may or may not be what you want. It may have thorns. Do a scratch test. If the wood above the graft is green your tree is still alive. If not, you have root stock. If you have green above the graft but allow the tree below the graft to develope leaves it will choke out the tree you bought for the root stock tree.

thanks all- I know that the rootstock is not what I want and I know the tops are still green, I knicked them- I will just cut the suckers from the bottom and hope for the best.

My lemon tree also took a bad hit from the 13 degree spell. However, in the past week, it has sprouted fresh leaves on the upper branches that were still green. Probly not get any lemons this year, but at least its living. Its not a grafted tree, I got it from a local nursery that either used seeds or cuttings. Year before last it had 7 lemons, past year, none.
