Seems like bugs attack leaves and whatever I do doesn't work
Suggested Project Book
Try applying food grade diatomeaous earth
Did you try Epsom salt? I get a lot of slugs attacking mine and this helps.
Sevin dust.
This is most likely slugs, you can always try the thing where you put beer in a cup and put the cup in the ground up to the rim. The slugs are attracted to the beer, fall in and can't get out.
I tried everything under the sun for the slugs enjoying my Hosta such as eggshells, copper, sharp gravel, beer, etc. The subject was brought up at my local Horticultural Society meeting and members said they had great luck mixing up a solution of Ammonia and water. Ratio: 1 part Ammonia to 9 or 10 parts water. They emphasized pouring it on as soon as the Hostas peek THROUGH the soil! Later on when the plant matured, they applied it (around the base of the plant; NOT on the plant) periodically through the Summer and after any rain. Believe it or not .... but there are Hostas that slugs won't eat - look for the larger species with very thick, heavily-veined leaves. They are just too much work for the slugs to munch through and they leave them alone.
Try growing Hostas in Hanging baskets using fresh compost!
