Absence Of Plants
As you may or may not know, we had quite a bit of rain and flooding over Spring here in Texas. This meant an excessive amount of humidity, and gnats. Tons and tons of gnats. They're still around, though finally not as bad. I'm a bit foolish and thought that opening my window (on multiple days) would be fine. I didn't realize that gnats can squeeze through a screen. They did, and made homes in my plants.
I've learned that mixing humidity and nasty gnats can be the death of houseplants. I had to count my losses, because no one wants bugs in their home. RIP plants. You are missed.
