The andromeda on the left started to turn completely brown--new growth, flowers,,then leaves, branches dried out. The progression of the decline is rather rapid-maybe over a week. Then the one next to it, etc. My next door neighbor's andromedas have started to exhibit the same problems (starts at the flowers and new growth first). Is it a fungus, borer, beetle or what? I cut them all back severely-will they come back?
If I remove them, what could I plant instead in a shady area as foundation plantings?
Thanks.
