Garden Update: Lettuce in Planters to Escape Summer Heat

Earlier this summer we planted lettuce into these planters on the east side of our house to provide us some summer salads after everything had bolted in our garden.  The seeds sprang up quickly and we were eating mesclun within a few weeks.  Unfortunately, a big storm took down the huge maple shading that side of the house in the beginning of July and one of the planters started getting fried by the sun and quickly went bitter than died.  The other one still looks lush and some of the lettuce varieties in the mesclun mix still taste good, but others don’t.  Next summer I need to move one of the window boxes and skip the mesclun in favor of a heat-resistant lettuce like Jericho lettuce.
