I can’t help feeling my houseplants are angry with me. As the snow builds up all around them, they seem to be saying “What are you doing? Get rid of that white stuff! It’s cutting off my light!” In the photo you can see the side of the greenhouse as the snow builds up. What you can’t see is that the roof is entirely covered in snow and has been since November. What use is a glass roof if it lets in no light during the darkest days of the year?
