The Greenish Thumb gave me the idea to call my enclosed porch a "greenhouse". It's because all of my outdoor plants are now in this space. For the most part, many of the plants are doing well, but there are a few that are struggling. Our house is 109 years old, and way back when, our enclosed porch used to be a regular porch. Somewhere down the line, one of the owners of this house enclosed it. When they did so, they never insulated the enclosed porch, so it's pretty cold in there. It's equivalent to an unheated garage. It keeps out the wind and the elements, but it's cold! I was out there watering the plants and saw that poor tropical Hibiscus wasn't doing so well. It looked droopy and pathetic. See how the flowers and leaves are hanging low.
