I'm so sorry. I can imagine how sad you must be. I have heard that leaving what's left of the leaves is good because they will continue to nourish the plant. But I think you should wait to hear from some of the more experienced gardeners who will no doubt post with an answer.

Those were some storms yesterday. I saw one area in NJ where they were actually plowing the hail, almost a foot. My hostas went through a hard freeze in early May. I left the leaves on as long as I could. But with all the rain we've had, they were starting to turn to mush. So I cut only the worst leaves off and left the rest. Aside from being smaller, they are fine. And yours will be too. If the leaves are shredded, leave them as long as you can so they can help feed the plant. If they start to turn to mush, just cut the mushy ones. Perennials have the will to live. Freezes, hail, being eaten to the ground by deer, drought, they will come back.

The best advice is to do nothing.The leaves are still doing there job of photosynthesis.New leaves will grow that are not tattered but the current leaves(tattered and beat up) are still doing a vital function for the plant.Cutting off the leaves will look terrible and do more harm than good IMHO.Phil

I agree....leave the tattered leaves this year.
You CAN cut them off and the plant will put out new undamaged leaves ( undamaged unless you get another hail storm) but at an expense to the vigor of the plant. It will be smaller next year than if you had left the leaves.

IGNORE THEM FOR TWO WEEKS ...

even a damaged leaf produces food ...

in 2 or 3 weeks.. go remove the worst 2 or 3 leaves ...

by the second flush.. though smaller.. they will look ok ..

AND THEY WILL SURVIVE ... dont give that another thought ...

last year.. i had a storm.. that for the first ten mins.. shredded the tree leaves ... the next 10 mins shredded the hosta.. and then cover the lawn like snow ...

i basically.. did not go into the hosta beds for the rest of the year .. except to turn on the irrigation ... it was a bad funk ..

this year.. they are fine..

good luck

Ditto on Ken. Had horrible hail storm come through last year and shredded all my hosta. I sulked all summer and winter long, but everything is doing great this year.
