Follow this detailed guide to ensure your Muhlenbergia capillaris thrives season after season.

PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Muhlenbergia capillaris in spring when the soil is workable. This allows the roots to establish before the warm growing season begins, promoting strong and healthy growth.
• Autumn: Alternatively, Muhlenbergia can be planted in early autumn. This gives the plant time to settle before dormancy, encouraging robust growth the following year.

Site Selection

• Light: Muhlenbergia capillaris thrives best in full sun. Choose a bright, open location that receives at least six hours of direct sunlight daily to achieve the best flowering display and vivid colour.
• Soil: Well-drained soil is essential. It grows well in sandy or loamy soil and tolerates poor conditions, provided drainage is good. If your soil is heavy, mix in grit or compost to improve structure and prevent waterlogging.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the root ball of your Muhlenbergia capillaris.
2. Soil Preparation: Mix compost or well-rotted organic matter into the excavated soil to boost fertility and drainage.
3. Planting: Place the plant so that the crown is level with the surrounding soil. Gently backfill and firm the soil around the base to eliminate air pockets.
4. Watering After Planting: Water thoroughly after planting Muhlenbergia capillaris to help the roots settle and ensure good soil contact.

Watering Requirements

• Growing Season: Keep the soil moderately moist during the first growing season while Muhlenbergia capillaris establishes. Once mature, it becomes drought-tolerant but benefits from occasional watering during prolonged dry periods.
• Dormant Season: Reduce watering in autumn and winter, only watering if the soil becomes excessively dry.

Feeding

• Spring: Apply a balanced, slow-release fertiliser in spring to encourage strong root and foliage growth. Muhlenbergia generally requires minimal feeding but benefits from this seasonal boost.
• Mid-Summer: A light top-dressing of compost or organic mulch in mid-summer can help maintain nutrient levels and soil moisture.

Pruning and Maintenance

• After Flowering: Allow the delicate pink plumes of Muhlenbergia capillaris to remain over winter for ornamental interest and structure in the garden.
• Early Spring Pruning: In early spring, before new growth begins, cut back the old foliage to about 5–10 cm above the ground. This encourages fresh, healthy growth for the new season.

Mulching

• Spring: Apply a light layer of organic mulch around the base of the plant to conserve moisture, suppress weeds, and maintain consistent soil conditions.
• Winter: A thin mulch layer in late autumn helps protect the roots and maintain soil structure during colder months.

Supporting the Plant

Muhlenbergia capillaris has a naturally upright, graceful form and rarely requires staking. However, in particularly exposed or windy locations, light support may be added to maintain its shape during flowering.

Final Tips

Muhlenbergia capillaris is a hardy, low-maintenance ornamental grass that adds movement, texture, and colour to garden landscapes. Whether planted en masse, as a focal point, or in containers, Muhlenbergia capillaris delivers a breathtaking pink haze that glows in the late-summer light. For best results, grow Muhlenbergia capillaris in full sun, water moderately, and prune annually. With minimal care, Muhlenbergia capillaris will bring year-round beauty and structure to your garden.
