I have potted up my plants to 6" pots waiting to put in their final pots when weather permits. I mixed the same soil for all the plants the same way. I had one plant give up on me a couple weeks ago, so I discarded it and replaced with another ready to move up in the world. Now that plant is looking miserable. It looks like it's wilting, but I know it has been watered on the same schedule as the others. I bought the pot from a local nursery, but I'm curious if this is more than a coincidence. I don't want to lose another plant. Any ideas?
