Keep Hostas Looking Great: Control Pests, Water Properly, and More Tips

Caring for Hostas to Keep Them Looking Their Best

Hostas are popular shade plants known for their wide, lush leaves. Properly caring for hostas is essential to keeping these perennials looking healthy and beautiful in landscaping beds and patio containers. This article provides tips to keep hostas looking their best all season long.

Preventing and Removing Slugs and Snails

Slugs and snails find the tender shoots of emerging hosta plants irresistible. Left uncontrolled, these pests can quickly damage hosta leaves and growth. Methods to prevent and control slugs and snails include:

• Physical barriers like copper tape
• Natural repellents
• Manual removal
• Iron phosphate bait

Watering Hostas Properly

Hostas need consistent moisture, especially as they are emerging and growing. But too much water can lead to rot and other problems. Effective watering strategies include:

• Watering early in the day to allow drying
• Soaking the soil deeply then allowing it dry out before watering again
• Adjusting watering frequency based on weather and soil type

FAQs

Why are my hosta leaves getting holes and looking damaged?

Holes and jagged edges on hosta leaves are usually caused by slugs or snails feeding on the tender foliage. Use physical barriers, natural repellents, manual removal, or iron phosphate bait to control these gastropod pests.

What is the best way to water newly planted hostas?

Water new hostas thoroughly immediately after planting to settle the roots. Then provide 1-2 inches of water per week by hand watering or setting up an irrigation system. Allow the soil to slightly dry out between waterings but don't let new plants dry out completely.

When should I divide crowded clumps of hostas?

The best time to divide overgrown hostas is in early spring as new growth emerges or in late summer after flowering. Use a sharp shovel or knife to break hosta crowns apart, retaining several shoots and roots with each division.

Can hostas grow well in containers?

Yes, many miniature and small hosta varieties adapt readily to patio pots and other containers. Use a quality potting mix, site containers in part or full shade, water frequently, and divide at the first sign of overcrowding in containers.
