My Gold Nugget has thorns on 80% of the branches. I planted it three years ago. I have read that these trees don't have thorns. They are not suckers. The branches start at about 10 inches above the ground. Do I have to prune them? I know that it is a Gold Nugget because the first year put out some fruit. It was very sweet but hasn't flowered again and I don't know why.
