Answer: Some plants just need a little time to mature before they perform well. Since your tree is growing and appears otherwise healthy, I'd suspect it's just a bit too young to blossom and produce berries. Continue to provide about one inch of water per week to the tree, and don't fertilize (or you'll end up with too much foliar growth at the expense of blossoms). Give it another year - it's sure to blossom then!
