Experts and BHG readers answer.
MY HOSTA''S ARE DYING AND TURNING YELLOW
Thanks for writing. I'm really sorry, but I can't say for sure what's going on in your yard without being able to see your plants. This free service really isn't meant for diagnosing plant problems like this where examining the plants and seeing where they're growing is necessary to give you a good answer.
I'd suggest you contact the folks at a reputable local nursery or your county extension office. Bring them samples of the affected hosta and creeping fig and they should be able to help better.
Good luck --- I wish I could help more.
