What do the Hoffmans do for a living?

Hello, everyone, welcome back to the program! We all know plants need the sunshine to grow. But actually not all vegetables need lots of sunshine. Mark Hoffman and his wife own a guesthouse in Kempton, Illinois. They often serve their guests fresh vegetables from their garden. For almost ten years, the Hoffmans have been experimenting with shade-plantings. Curious visitors often ask how they do it. Here is the answer. They grew tomatoes near the trees that produce a lot of shade. Tomato plants grow as long as they get five hours a day of direct sunshine, especially morning sun. This goes against the traditional advice that tomatoes need eight even twelve hours a day of full sun. Besides tomatoes, the Hoffmans grow Irish potatoes. Plants with wider leaves seem to do better in shady environments. The potatoes grow better in the shade than in full sun.
