Caffeinated Hostas

This giant hosta is 4 1/2 feet across. He's in the garden right outside my front door.  His sister is on the other side of the front steps.   If I laid on it, think of my belly dead center, my fingertips would be able to tickle the leaves on the outer rim.  That's one huge hosta and it just keeps growing year after year.  And I love it.  This is another of the many plants I do nothing to promote.  But I do defend this one.  Last spring as it started unfurling into this giant radius I was awestruck at the size and appearance.  There were no buds visible in the dirt and then...this!  One morning last spring as I wandered my garden I noticed my awesome hosta had been somebody's midnight snack. Or was it bugs?  Some rare disease?  Dog-sized rabbits?  Hugs chunks of hosta were gone like somebody/thing had nibbled the night away.  I was in my FaceBook days, so  I posted on the town community garden page, "What's going on here with my hosta?"  I received a range of responses but it seemed the deer were enjoying a vegetarian moonlight munch.  So then I asked, "What do I do?"  One FaceBook reader wrote,  "Let them eat!" And another, "Have your husband pee on the hosta."  And another, "Who are you to take away food from the deer!"  You see why I am no longer a FaceBook "friend."  My northern Maine friend who is a fabulous gardener, no brown thumb for her, told me to get a natural spray, "Deer and Rabbit Repellent."  $35.99 for 2 ready-to-use quarts.  However, my husband and I noticed that only the larger of the two hostas were eaten.  This guy smiling for the photo.  His sister on the other side was untouched.  And then we also noticed coffee grinds on the smaller uneaten, sista hosta but not on the larger.  My husband and I were in the habit of flinging out old coffee grinds onto that smaller hosta.  We'd just open the door in the morning and fling grinds to left.  We deduced, correctly, that deer don't like caffeine.  These days I purposely shower decaffeinated coffee grounds down on the big guy while my husband continues to sprinkle his caffeinated rinse water on his sister.  Who knew?  Goggle it.  It's a little known environmentally friendly deer deterrent.  No evidence to support this other than my giant happy hostas.  I guess if that stops working we can have my husband pee on them but if I could lure a mountain lion near, supposedly his/her pee works better.
