    I planted three 5′ tall, 1 inch caliper Shumard Oak trees two years ago. Clay soil. I have seen almost zero growth. At the same time and in the same area I also planted three similar-sized Live Oaks, which have grown about 2 feet. Any ideas why the Shumards are growing so slow?

      Hello, Brian. It’s probably the clayish soil, the live oaks planted nearby may have been planted where the clay soil is not as deep. Yes, the soil can vary from one short distance to another. It’s common around this area.

      Try incorporating some gypsum into your soil where the Shumard oaks have been planted. You can also use Helena’s 16-8-8 fertilizer as it contains some gypsum. The only problem with gypsum is that it will take a few years before you see good results. You might want to read this post on water smart plants there is a section on the clayish soil.

    Does the Shumard oak loose all of it leaves in the winter time?

      Hi, Mike. Yes, the Shumard Oaktree will lose all of its leave in winter right about the end of October or early November. Actually, all Oaktrees will lose their leaves in winter. Except for the Live Oak, it will retain it leaves throughout the winter seasons. More about the live Oak here.
