The sun's been so intense lately that it's been frying leaves on my african violets.
Can't move the shelves to a different window... don't have any others that get any light.
Can't do anything to the window, since it's actually a sliding glass door.
What to do?
Why, tape some parchment paper across the back of the shelves, of course! Voila, the light is filtered and won't burn the plants anymore!
I'm so proud of myself for thinking of it!
