Garden standbys, hostas come in a variety of colors and sizes from tiny selections suitable for rock gardens to huge numbers with umbrella-sized leaves. There are hostas with multicolored foliage, ruffled and rippled foliage, some with stunning blooms, even fragrant blooms.
The blue-ish varieties come with a built-in wax coating on their leaves which helps them in two ways. No. 1 is that these hostas tend to be a bit more sun tolerant, and No. 2 is that they possess a slightly better resistance to slugs and snails.
Indeed hostas are a prime target for those slimy slugs and snails. But of course you don’t want to resort to harmful chemicals to keep them under control. Relax, there’s a quick and simple cure that can be mixed from items most of you already have on hand.
Zap slugs and snails with a mix of plain old household ammonia and water. That’s right, just combine three parts water to one part ammonia and spray the creepy crawlies away. Best time to spray is early evening when they are out and moving around. The spray must touch the slugs/snails in order to work and does not provide any residual benefit. So you may need repeat sprayings to control a bad infestation.
But, trust me, you are going to love using this simple concoction! The slugs and snails literally turn to mush before your eyes with this simple spray that does not harm hostas and most other plants. (One exception is the bleeding heart/Dutchman’s britches group of plants.) If there are any doubts, try it on an inconspicuous spot first.
