Hostas Dying Out #341534

We have had hostas growing in our front yard for 20+ years & they have always flourished. But this spring, 1/2 of the hostas in a small patch never came up. Then gradually over the summer, the ones that did come up are slowing dying away. There is a 2nd patch of hostas (same type) just across the sidewalk & they have not been affected. I am attaching 3 photos: First a larger view showing the 1-2 plants that are left from the previous whole row, then 2 photos of the remaining plants closer up. The only thing that changed in this garden area is that we transplanted a hydrangea plant into that area 2 years ago. Otherwise, nothing else has changed.

I would suggest that somehow a broadleaf weed killer got into the soil. If a weed and feed was used this spring on your grass and some got into that area, that would be the cause. Or, if something was sprayed in the area by a lawn care company or utility. You will have to do some detective work. If that is what happened, the area should be safe to plant next spring.
Thank you for your response. That doesn't seem likely though, as we do our own lawncare, & the hostas in this patch are way back by the front porch, 3 feet away from any grass. The hostas across the sidewalk are adjacent to grass & are thriving well. Is there any other possible explanation? This is such a mystery to us! Thank you for your input!

I have no other explanation unless you have a problem with moles or gophers under the soil. That would disturb the roots and gophers could be chewing on them. I suppose there could be grubs also but usually they affect grass roots. As I stated, you will need to do some detective work. Sorry.
