Hostas require very little maintenance during the growing season. They need little more than some shade, good soil and moisture to flourish all on their own.
Watch for rabbits in spring–this is their favorite time of year to munch on hostas. Just as their pointed tips emerge from the soil, a hungry bunny may come along and nip them off. It won’t hurt the hosta but once its leaves unfurl, you’ll see the bunny’s teeth marks. Avoid this by applying animal repellent on your hostas in early spring just as they start to come up.
If deer are an issue in your garden, consider growing more deer resistant plants or plan to protect your hostas with animal repellent or fencing. Taller, thinner leaved cultivars are more prone to damage simply because they are easier for the deer to eat.
During wet weather, slug populations can multiply quickly. If you start seeing holes in your hosta leaves, it’s a sure sign that they have moved in. Here is an article to help you “slug it out” with these pesky creatures.
Hostas should be cut back in fall once their foliage has gone to sleep for the season. Remove the spent foliage from the garden bed and dispose of it to help avoid future slug damage around the plants.
