Stay Cool in the Garden!
Some tips for gardening on days like today where the temperature will be approaching 100 degrees
1) Keep Yourself Watered
2) Remove Weeds
3) Apply compost to keep moisture in the ground.
4) Let the hot sun work for you by tilling unused areas of the garden and expose the soil to the heat. This will kill nematodes and young weeds. After a couple of weeks repeat tilling to bring more weed seeds and nematodes to the surface. (Source: Weather Channel Article) Very Good Idea!
