Carolyn, The Gardener's Supply company (gardener.com) has several models of "Stand Up" raised beds that would work for you. Smoothies are a great way to get lots of veggies and fruits into your diet. I drink one every day. My secret is to flavor the drink with 1/2 cup of pomegranite juice. I put a handful of kale in the blender and never know it's there. My best to you and good luck on your recovery. Nancy and Happy Yardening.
