How to Stop Pests From Eating Hosta Plants

Overview

Hostas, with their large, mounded foliage in solid and variegated shades of green, are one of the simplest perennials to grow and maintain. A relatively disease-free plant coveted for its hundreds of varieties, hostas are a staple in shade gardening. If there is a downside to this versatile plant, it's its vulnerability to pests, mainly slugs and snails.

Slugs and Snails

Step 1

Inspect the underside of your hostas for any slugs or snails in the early evening. Look for evidence of these hungry pests, such as slime trails, which leave a silvery streak.

Step 2

Pick up any visible slugs and throw them into a bowl of soapy water to kill. Look for slugs in the evening hours or after heavy rains.

Step 3

Place a shallow dish of beer near your hostas; the slugs are drawn to the scent and will climb in and drown. Check regularly for dead slugs.

Step 4

Place wet newspaper in your garden near the hostas overnight. Early in the morning, remove paper to discard any slugs or snails taking refuge underneath.

Step 5

Sprinkle a commercial slug bait around your hostas in early spring as directed by the product's instructions.
