It looks like sun damage or transplant shock. Just keep it damp but not soggy. It should be fine.

I have lost a few new hostas , but usually they are pips that never grow and then rot, or hostas that look wilted. Manzo did that this year. It went limp when it was planted. I kept pouring water on it, and eventually it rotted, proving you can overwater a hosta.

Stress, keep watering, should be ok next

Well they actually looked like this when I planted it them, they had already started geting yellow before the transfer. Does that change your opinion?

I received my Waterslides 10 days or so before they got planted.

===>>> when was this???

notice the worst are all the oldest leaves ... something happened way back when .. and lasted long enough.. to affect the second set of leaves ... in a more minor way ....

im wondering if this happened when the shipped it to you??

did it come bare root?? ... could have been a cold event ... or dryness event ...

you water a pot.. when it needs water .. many of the peeps who are the pot mavens ... live in areas that require daily watering.. but that might not mean in your area.. that it needs water every day ... and the biggest variable is the potting media ... so that may or may not be an issue ... but if it didnt rot from too much water.. i discount that as an issue ...

it is not uncommon.. with small plants.. that they basically do nothing the first year ... plus yours had some stress ... and its getting ugly.. a few weeks early ... though we all may live by that river... de nile ... it is ALMOST september.. and fall ...

just keep it moist thru late fall.. and it should be just fine come next spring ...

If it came potted, it might have been potted in a moisture control potting soil which can hold too much water for a hosta’s drainage requiring root system. Did you bare root them before you planted them?

They arrived in the pots seen in the photo in I believe potting soil. I did not bare root them. Never heard of doing this. I had learned to remove a plant from the pot, loosen the roots, and plant using the Soil it came with. When I received them, one plant had a tiny bit of yellow around part of the edge. That said, I watered them every day, except when it rained, which we haven’t had much of recently. Soooooooo, it would appear that I watered them too much........ :-| Duh!
