Green Thumb-Yes.
I had a young lemon tree years ago that was 99% ring barked by nibbling critters. I dug it up and put it into our hot house.
My wife thought it carked it and bought another one to plant next to it. I kept reminding her, where there's life there's hope and refused to believe it's demise until it showed signs on being so.
The replacement lemon tree died and my saved tree produces fruit. So I guess I have a green thumb.
I had a similar experience with a fig tree which planted itself in our garden, presumably from a seed dropped by a bird. It lived in our garden for several years quite happily but never produced any fruit. Eventually my mother decided it was just wasting space and asked our garden service to dig it up.
This was about the time I was first getting seriously involved with bonsai and I refused to let that tree die. I cut off almost all the roots before planting it in a large pot. It quickly adapted to its new home and went on as before. Now, several years later, it has produced its first two fruit and I'm anxiously waiting for them to ripen.
At the time my mother bought a tiny fig tree which had a couple of figs on it. The first year the birds got them. The second year we tried to avoid this by picking them before they were ripe and they never ripened. While producing fruit, the tree never got any bigger and the third year it died.
