Curtis Swift says if you use cloth sheeting, suspend it at least five centimeters above the plants. That way there is enough space for bees to fly around. Be careful not to cover plants too closely, which could trap heat and defeat the purpose of shading.
People can also buy canopies to shelter their plants. Some canopies have narrow strips of metal or wood to provide either sunlight or shade, depending on the position of the sun.
Curtis Swift says shading works with field crops as well as vine crops like squash. People sometimes plant shrubs or trees to shade their vegetables. But he says tree roots compete with the vegetable roots. The veggies may not get enough nutrients and water.
And that’s the VOA Special English Agriculture Report, written by Jerilyn Watson. Here are a few of your comments about last week's report on shade growing. Ko from South Korea wrote:
I can't imagine plants in the shade for most of day without sunshine! That's a really creative idea.
Andy in Chile wrote:
This is an interesting article. But you forget that the shadow allows the growth of the fungi.
And Slava in Croatia recalled:
Once I grew small tomatoes on a balcony under a roof. Sun shone there only in the afternoon. In October the plants had only a few green tomatoes. I took them inside behind the window and they had ripe fruits on Christmas and the entire winter.
