I am in deep trouble. My 'Maggie May' has wilted and looks very sick. Not enough water? fertilizer? Are Hostas short lived? Do they need to be mulched over the winter? Are there Hosta beetles? Could it be moles or voles? Accidental herbicide drift? OR, are they not noted for winter interest?

Hosta's are long lived, they do like water, looks like it is going into dormancy. They do not needed to be mulched over the winter, but a cover of leaves does not hurt them. Voles can be a problem. Thinking you will see it reemerge in the spring.

Yours has more green in it then any of mine at this point , like RJ said just going dormant for the Winter. It happens to some varieties well before others. Some of mine were gone over a month ago. Moles really do not bother Hosta and if it were Voles the roots would be gone.

My Tootie Mae went dormant a last month. I don't think there's any green ones left out there.

If you are new to growing hostas, you should know that hostas require a period of dormancy and quite cool temperatures in winter. As others have said, some will last longer in autumn than others, but all of mine were gone several weeks ago and the last few weeks, they don't look their best. If yours was newly planted this season, if would benefit from some mulch over the winter, but look for it to re-emerge bigger and better in spring.
