July 04, 2012
Tomato Dirt Newsletter
Here’s the good news: a heat wave will not likely be fatal for your tomato plants, especially if you can keep them watered. And more good news … tomato fruit already on the vine and ripening will likely be OK when it’s super hot outside.
Unfortunately, tomato blossoms are another matter.
Two problems for tomatoes in a heat wave:
You can reduce stress on your plants during a heat wave by watering them at least once a day. Increase frequency of watering without increasing the amount of water the plants get to avoid water logging and killing the plants.
A second trick to managing tomato plants during a hot spell: give them shade! (Read the full article...)
You can use many materials to shade plants. Some gardeners drape old sheets or burlap over supports. Some set lattice panels around tomato plants to diffuse light. These materials can keep some light off plants.
But shade cloth is a fabric constructed specifically for shading tomatoes. It keeps a larger amount of UV rays at bay and reduces the impact of light. Shade cloth is either knitted or woven. It's rated by a percentage figure, which indicates the amount of reduction in light it achieves. For instance, 50% shade cloth reduces the amount of light the plants receive by 50%. The cloth also achieves a reduction in temperature, usually about half the amount of light. 50% shade cloth will reduce heat by 25%.
Woven shade cloth, knitted shade cloth, aluminet shade cloth, and all-purpose garden fabric are available in different weights and sizes, depending upon what you need. (Read more about what to use to shade tomatoes …)
