Some of the potted plants have a little bit of a gnat problem going on. After I water them, they get particularly pesky. So I went around spraying everything with a concoction I made of vinegar, rubbing alcohol, and water – my shower/bathroom cleaner essentially. And I killed some of the plant stems. The philodendron stems went black and I had to cut them off and re-root them in water.
And so did the baby spider plant. Luckily the mother spider plant survived the blasting.
