You’ll want to remove the burnt pothos leaves. As the dead leaves will not recover and look healthy again. But be careful to remove only a few leaves, as the plant still needs to be able to photosynthesize.
Exposure to direct sunlight for extended periods can also dry out your plants’ soil. Use your finger to check soil moisture to a depth of 2-3″ inches, or use a moisture meter to probe deeper.
