Getting a good harvest through the summer, particularly in areas where temperatures regularly rest above 90F (32.2C), can be challenging. Today, it’s 97 (36.1C) and still. I watered early in the morning. A thick layer of straw mulch covers the ground around all the vegetables, and shredded bark mulch protects the ornamentals, but it doesn’t feel like much help.
Seeing my plants droop in the heat makes me depressed. More importantly, heat-stressed plants are more susceptible to viruses, fungal diseases, and all sorts of nasty stuff. So today, in anticipation of these ghastly temperatures, I went spelunking in the shed and found the old patio umbrella and cast iron stand. I set them up on the southwestern corner of the raised bed, where the umbrella shades the beans, tomatoes, and some of the peppers from noon until sunset. They do get morning sun, as well as reflected light all day from the gravel paths close by.
It may sound ludicrous, but providing your vegetables just a tiny bit of shade, particularly from the afternoon heat, can make a big difference in their resiliency over the season. Give it a try.
