If you like to sow lettuce every couple of weeks for season-long harvesting, this shade cover can be a big asset for plantings during the hotter summer months. By filtering the sunlight, the screen helps prevent the lettuce from quickly going to seed and becoming bitter.
Cutting the lumber. From the 2"×2", reserve two 36" lengths for the front and back of the cover frame . From the remaining 2"×2", cut two 17¾" lengths for the sides . Also cut four 16¾" lengths for the legs and round the corners (this will keep the leg tops from rubbing on the lattice when you collapse the shade cover for storage at the end of the season).
Constructing the shade cover. Make up the frame by attaching the front and back to the sides . Attach the legs with single screws, as shown in fig. 1, so that they will pivot. Then attach the lattice to the top of the frame.
Keep It Cool
Not all plants like full sun. Spinach, for example, doesn’t germinate well in very warm soils. Placing a shade cover over a planting area a week ahead of time can help moderate the temperature. It’s also a good idea to shade the emerging seedlings and young plants during hot spells (above 80°F/27°C) to prevent wilting and bolting. Lettuce, too, should be kept partially shaded when grown in warm weather.
