I have been cutting the leaves off as they turn brown hoping that maybe whatever it is it wouldn't spreadBrown spots in plants can be a lot of potential issues. Maybe nutrients, light scorching, humidity issues, fungal or viral disease. What conditions are the plants in? How is the drainage? Does a lot of water tend to sit on the leaves? Do the brown spots seem mushy?
Thanks! That makes perfect sense and sounds like what i have going onThe plants look like rooted bunches from a vendor, which are usually grown in higher light and lower moisture compared to most frog vivs. The old foliage often dies back and the new growth will be better suited to your conditions.
Also, a few of the plants shown tend to get dead spots on their foliage, even with just a little standing water.
Also also, new vivs with a bunch of fresh leaf litter tend to get mold booms and busts, which can sometimes take advantage of the plants.
I don’t remove the spotty leaves on my plants. If I was meticulous about immaculate foliage, I’d let those plants establish, then cut them at ground level. The new growth would be good, and now I have extra cuttings.
