I order plants online quite a bit and I noticed something that happens with plants that there might be a name for. I discribe it as Plant deadheading Itself because it literally picks a spot just below the leaf and withers there but leaves the rest of the stem looking healthy. It happened when I recieved my monstera and now happened to one of the leaves on my newest begonia addition. So what gives?
Here are some pictures, lookng forward to hearing your responses!
