PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Eragrostis spectabilis in spring when the soil begins to warm. This allows the roots to establish well before the plant starts producing its characteristic cloud-like flower heads.
• Early Autumn: Eragrostis spectabilis can also be planted in early autumn, giving it time to settle before entering its natural dormant period and preparing for strong growth the following year.

Site Selection

• Sunlight: Eragrostis spectabilis performs best in full sun. Choose a spot that receives generous light to help the grass maintain its colour and produce abundant, airy flower sprays.
• Soil: Ensure well-drained soil, as Eragrostis spectabilis dislikes excess moisture around the roots. Add compost or grit to improve texture and drainage if required.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and of equal depth. This allows Eragrostis spectabilis to spread its roots freely.
2. Soil Preparation: Mix in organic matter or compost to enhance drainage and provide the plant with a strong start.
3. Planting: Position Eragrostis spectabilis in the hole so the top of the root ball sits level with the soil surface. Backfill gently and firm the soil to remove air pockets.
4. Watering After Planting: Water thoroughly to settle the soil. Ensure the planting area drains well to prevent prolonged wetness around the roots.

Watering Requirements

• Growing Season: Once established, Eragrostis spectabilis is naturally drought-tolerant. Water during extended dry periods, allowing the soil to dry slightly between watering. Avoid overwatering, as persistent moisture may lead to root issues.
• Dormant Season: Reduce watering significantly during dormancy. Only water if the soil becomes unusually dry.

Feeding

• Spring: Apply a light, balanced fertiliser in spring to support fresh growth and help Eragrostis spectabilis develop a healthy clump.
• Mid-Summer: A gentle mid-summer feed can boost the production of its soft pinkish-purple seed heads and maintain overall vigour.

Pruning

• Cutting Back: In late winter or early spring, cut back Eragrostis spectabilis to ground level before new growth emerges. This keeps the plant tidy and promotes a fresh flush of foliage.
• Tidying: Remove any spent flower stems through the season if desired, although many gardeners enjoy their ornamental value.

Mulching

• Spring: Apply a thin layer of mulch around the base of the plant to help retain moisture, suppress weeds, and regulate soil temperature. Use compost, bark chips, or similar organic materials.
• Winter: A light mulch can provide root protection during colder periods without trapping too much moisture.

Supporting the Plant

Eragrostis spectabilis has a naturally upright, arching habit and rarely needs support. In very exposed sites, consider giving minimal protection to prevent wind damage, but staking is usually unnecessary.

Final Tips

Eragrostis spectabilis is a low-maintenance ornamental grass that brings movement, colour, and structure to borders, gravel gardens, and naturalistic plantings. By planting Eragrostis spectabilis in full sun with well-drained soil and following this simple care routine, you will enjoy its graceful form and airy seed heads from summer into autumn. Incorporate this Eragrostis into your planting schemes to add softness and year-round appeal to your outdoor space.
