I have five houseplants that seem to be dying or are almost dead. They are a Golden Pothos, a Dark Mystery Pilea, a Philodendron Scandens, a Pink Polka Dot Plant, and a Lipstick Plant. The Pothos, Pilea, and Philodendron were all purchased from Walmart over a year ago and are from Costa Farms. The Polka Dot and Lipstick were bought from a local food store. All were much smaller when I got them and have grown large until recently (about 2-3 months). I had them on a large cardboard box originally but started seeing tiny flies/gnats. I used a houseplant bug killer from Garden Safe Brand to eliminate them but still see them at times.
I now have the plants all on a plastic shelving unit I purchased for them right near my south-facing window. It is the only window I can put them in front of without tripping over them, and they get morning and some afternoon sun. I have all the plants in a moisture-control soil from Miracle-Gro and water them when the top is dry. I also feed them with a liquid fertilizer from Miracle-Gro every month. I have mixed the dirt around in their pots, so there is no stale soil on the top for too long. I also have a long stem that broke off from the Pothos replanted after I put it in water until it sprang roots. Now the Pothos keeps getting leaves that turn yellow and brown, the Philodendron's leaves all look droopy and keep falling out, the Polka Dot has mostly lost all of its leaves, the Lipstick has turned brown and thinned out (looks dead), and the Pilea has lost all of its leaves, turned brown, dried up, and thinned out all but 1 stem. Help! I love my plants and want to make them great again! The first 8 photos are what they look like now, the next 4 are what they started to look like, and the last is of one of the flies/gnats.
