Sorry to hear of your problem. Sometimes root rot can cause this. Check for standing water, or rodents burrowing near the root. Also, try adding some seaweed solution to it every couple of days. It is a stress reliever for plants and maybe it can help. Good luck.

Is it all over the plant or on a section, Barb? If it's not all over I'd just remove the impacted pieces. Do you give it supplemental water? If you water in a way that the stream hits the foliage I'd change that so that only the ground is wetted. I've never sprayed my peonies, we're pretty dry here in CO, but have heard of people/growers using fungicides for mold issues.

I might look for a lamp that could move forward on the chest enough (without danger of toppling off) that the shade just hides that thermostat. Place it just a couple inches to the right of where it is now, or move the whole chest to the right a bit. It won't affect the functionality, esp if you use an LED bulb = no heat. Then look for a large piece of art, or a couple of stacked pieces to fill in over the right side of the chest, as shown above. Another idea is a gallery wall incorporating the thermostat: I would trade you those beautiful folded blankets for the star wars lego decor my grandson has decorated my house with! eta: I was just looking at it again and think Cyn's idea to switch the cabinets would work. You could then place the floor lamp in front of the thermostat and just ignore it.

The first 2 plants need to be watered when the top inch of the soil is dry. The second two are Aloe and Gasteria, they need to dry a little bit more before watering them. As Karen mentioned, don't splash water in the plant as it can rot the crown of the plant ( the water doesn't evaporate fast enough in the nooks where the water will settle and can cause rot). Best practice for watering is to water till excess water drains out the bottom drain hole. Never allow the pot to sit in water for more than say 15 minutes, pour off all the excess water. Light: first two need bright indirect light, the second two want some direct sun to full sun. But remember when placing a plant into direct sunlight, it must be acclimated to full sun. Plants not in direct sun will sun burn if placed into full sun to quickly. Acclimate by placing in direct sun light for short periods and increasing the length of exposure as the plant gets used to the stronger light.
