The Hoffmans' website includes a list of vegetables, flowers and herbs that have produced acceptably for them in partial shade. Besides tomatoes and asparagus, these include broccoli, daylilies, horseradish, Irish potatoes, oregano and winter onions.
Mr. Hoffman says plants with wider leaves seem to do better in shady environments. He also found that his potatoes did better in partial shade than in full sun.
Moving them out of the sun helped control an insect problem with leaf hoppers. Mr. Hoffman does not use pesticides. Instead, he planted the potatoes at the drip line, especially on the east side of the tree.
The potatoes get morning sun, but they are shaded during the hottest part of the day. Leaf hoppers dislike shade, and the hottest part of the day is when they do the worst of their damage.
Time of day. Brightness of the sun. Shadows from trees, walls and buildings. These all influence how much sunlight falls, or does not fall, on plants. And extension agent Curtis Swift at Colorado State University says people interested in shade planting should also remember something else. The term "shade" can describe different amounts of darkness. He says it can even mean different things in different parts of the world.
And that’s the VOA Special English Agriculture Report, written by Jerilyn Watson. I’m Bob Doughty.
