The last few weeks have been cool (60s) and rainy in the Chicago area. Today it spikes to 90 degrees. My mesclun mix sprouted two weeks ago and is now subjugated to the blazing hot sun. Does this drastic spike in temperature affect the lettuce? It’s supposed to stay in the 80s the next few days before returning to more normal temperatures.
I started over on my earliest salad plantings for similar reasons. First they limped along in wet/cold, then they got a baking and then we went back to wet/cold. RE: the blazing sun stuff, erect a piece of shadecloth over the tender things to give them a break perhaps. You can use Reemay fabric and clothespins and old coat hangers or but “frames” from a garden supply place made for suspending shade and other protective fabrics.
