I HAVE PLANTED SEVERAL FRUIT BEARING TREES ON MY PLACE IN TEXAS AND WAS WANTING TO PLANT AN ORANGE TREE AND GRAPEFRUIT TREE AS WELL. HOWEVER, WHEN I WENT TO LOOK FOR THESE THEY ARE AVAILABLE AND CANNOT BE SHIPPED TO TEXAS RESIDENTS. WHY IS THIS I ASK ? DOES THE TREE NOT DO WELL IN THE TEXAS CLIMATE, OR DOES THE LAW PROHIBIT IT. DOES ANYONE KNOW WHY THIS IS.
