I have a couple of pepper plants that I've recently procured. Since I do not want these to go the way every other plant that has been gifted to me (i.e. death), I transplanted them into some large planters and used "moisture-control" potting soil, and applied a 3" layer of mulch to the surface. Being that I live on the surface of the sun (Phoenix, AZ), I've had to rescue my poor peppers from the sun a couple of times, despite advice that peppers love the sun. The planters were getting too hot, the moisture seemed fine, and the planters were in shade most of the time, but I could see visible signs of stress on the plants. I had to water them to cool the soil.
So what I'm asking is:
- Should I remove some of the mulch to allow the soil to dry (recommended by people for peppers)?
- Should I put them in an even more shaded area?
- Should I be concerned about plant diseases germinating in such a hot and humid environment?
