Planting Instructions (From a Bareroot into the Ground)

1. Choose the Location

• Select a shaded or partially shaded location with rich, well-drained soil.
• Ideal beneath trees, along woodland paths, or in shaded borders.

2. Prepare the Soil

• Loosen soil 10–12 inches deep.
• Mix in compost or well-aged organic matter to improve fertility and moisture retention.

3. Prepare the Bareroot

• Soak the bareroot in water for 1–2 hours before planting if it appears dry.
• Inspect the crown and roots, trimming only damaged roots if necessary.

4. Dig the Hole

• Dig a hole wide enough to comfortably spread the roots.
• Form a small mound of soil in the center of the hole.

5. Plant

• Position the crown so it sits level with or just slightly below the soil surface.
• Spread the roots evenly over the mound.
• Backfill with soil and gently firm around the roots.

6. Water Thoroughly

• Water deeply immediately after planting.
• Keep the soil evenly moist during the first growing season.

7. Mulch

• Apply 2–3 inches of organic mulch around the plant to retain moisture and suppress weeds, keeping mulch away from the crown.

8. Spacing

• Space plants 24–30 inches apart to allow for mature growth and good air circulation.

Overwintering Devon Green Hosta

In-Ground Plants

• Fully hardy throughout USDA Zones 3–9.
• Foliage naturally dies back after the first hard frost.
• Cut dead foliage to ground level in late fall or early spring to reduce overwintering pests and disease.

Winter Care Tips

• Apply a 2–3 inch layer of mulch after the ground freezes to protect the root system in colder climates.
• Remove mulch from directly over the crown in early spring as new shoots emerge.
• Ensure the planting site has good drainage to prevent crown rot during winter.

First-Year Plants

• Newly planted bareroot hostas may produce fewer leaves during their first season while establishing roots.
• Plants become fuller and more vigorous with each passing year.

Container-Grown Plants

• Move containers to a sheltered location during winter.
• Insulate pots or bury them in the ground if possible to protect roots from repeated freeze-thaw cycles.
• Water lightly during prolonged dry winter periods if the soil becomes completely dry.

Devon Green Hosta is an elegant, dependable shade perennial that offers rich emerald-green foliage, graceful lavender blooms, and excellent garden performance. Its glossy leaves, compact habit, and improved slug resistance make it a superb choice for woodland gardens, shaded borders, foundation plantings, and containers, providing season-long beauty with minimal maintenance.
