Coral Bell Leaf Browning

The lime green Coral Bells that I planted last year are turning brown around the edges. I have tried a "raised bed." I used one dose of a fungucide.
Doug says it isn't a fungus. It's a watering problem (either too much or too little). Likely you've managed to underwater it in the raised bed (raised beds take more water than ground-level beds) and that's the result.
Here's a video on how to water plants. It's the same rule and the same finger for indoor and outdoor plants.
