Muhly grass: Adding beauty and movement to your landscape

Ornamental grasses are admired by many for beauty but are sometimes difficult to grow. If improperly maintained, these plants may struggle to adapt to poor soil, grow too quickly, attract pests or lose their shape. Other grasses require regular mowing or don’t endure extreme weather so that they can be challenging for new farmers. But not all ornamental grasses demand much attention. One such low-maintenance grass is Muhly grass (Muhlenbergia capillaris).

Unlike other ornamental grasses, Muhly Grass is known for its soft, feathery pink plumes in late summer and fall. They are delicate flowers that create a cloud-like effect, wispy and swaying in the wind. Besides its graceful looks, this grass is drought-resistant, thrives in poor soil and needs very little maintenance, which makes it a stunning option for either novice or experienced gardeners.

Growcycle offers cloning machines, seed starting supplies, and rooting hormones for propagating plants like this Muhly Grass.

Origin and History

Muhly Grass (Muhlenbergia capillaris) is a North American native grass that is native to Florida, Texas and the southeastern United States, as well as parts of New England. It is native to open woodlands, prairies and coastal plains, where it is adapted to well-drained sandy or rocky soils. This resilient grass thrives in hot, dry climates and can commonly be found along roadsides, in meadows, and in dunes, which help avoid soil erosion.

Indigenous peoples and early settlers understood the value of Muhly Grass historically. Some Native American tribes used the plant’s tough, fibrous stems to weave and craft items. Its erosive soil fixation properties also made it into an essential plant for the prevention of land degradation in coastal and sandy areas.

Muhly Grass has grown in its native habitat for centuries but became very popular in landscaping in the late 20th and early 21st centuries. It became popular with gardeners and landscape designers for its delicate pink plumes, drought resistance and low-maintenance nature. Its ornamentally attractive foliage has led it to be widely used in public gardens and in residential and commercial landscapes today, where it adapts to different sites.

Varieties and Species

Muhly Grass, (Muhlenbergia capillaris), is famous for its pink plumes. However, a number of other species within the Muhlenbergia genus are also used in gardens and public landscapes. Cactus types all look slightly different , which makes them suitable for certain conditions and design styles.

Growing Muhly Grass: A Practical Guide

Muhly Grass is an easy-to-grow plant that requires little maintenance. Nevertheless, if  offer plant the conditions it needs to grow and follow correct planting practices, it should grow vigorously and bloom beautifully. Here is about soil and climate requirements, maintenance and troubleshooting advice of this grass:

Ideal Growing Conditions

If anyone want to grow Muhly Grass successfully, it is important to replicate its native habitat as much as possible.

1. Climate & Hardiness

• Muhly Grass does well in warm, temperate, and subtropical regions.
• Optimal for USDA Hardiness Zones 6–10.
• In zone 6, it may die completely back in winter, but will regrow in spring.
• In Zone 9–10, it remains green throughout most of the year but still benefits from seasonal pruning.
• It is tolerant of light frost, but prolonged freezing temperatures will damage the plant.

2. Soil Requirements

• Well-draining soil is a must! Muhly Grass can not stand wet or compacted soils.
• They thrive best in sandy, rocky or loamy soil with proper aeration.
• It does best in a soil pH of between 5.5 and 7.5 (slightly acidic to neutral).
• Add sand, compost or perlite to heavy clay soil in order to promote drainage.

3. Sunlight Needs

• To grow and bloom the most, full sun (6+ hours of direct sun a day) is best.
• It will take some shade but it will make for weaker stems and less flowering.

Step-by-Step Planting Instructions

Proper planting ensures that Muhly Grass establishes quickly and remains healthy throughout the year.

1. Choosing the Right Time to Plant

• The perfect time to plant is early spring (after the last frost) or early fall (6–8 weeks before the first frost).
• Plants have time to mature their roots before the summer heat.
• Planted in fall, the roots grow in cool soils, allowing them to get mature for spring.

2. Site Preparation

• Clean the area of weeds and debris.
• If soil is compacted, loosen it at 12 inches deep with a garden fork or tiller.
• If required, mix in sand or compost to improve drainage.

3. Digging and Spacing

• Dig a hole 2 times the width of the root ball but only the depth of the plant’s original pot.
• Spacing: 2–3 feet apart spaced for complete maturity and air circulation.
• Plant too deep, and it will lead to root rot.

4. Planting and Initial Watering

• Carefully take the plant out of its pot and loosen the roots if they are root bound.
• Put the plant in the hole and backfill with soil, pressing lightly to eliminate air pockets.
• After planting, a water well will help settle the roots.

Watering Needs

For the new Muhly Grass to root itself, it needs frequent watering. For the first 6–8 weeks, water twice a week, keeping the surface soil, the top 1–2 inches, moist but not flooded. Once established, this plant is extremely drought-tolerant and requires very little watering.

After the first couple of months, watering once every 10–14 days during dry periods should be enough. Most climates get sufficient moisture from rainfall, other than extreme drought. As with over watering, too much moisture will rot the roots and reduce the plant’s vitality.

Fertilization Tips

Since Muhly Grass is native to nutrient-poor soils, it doesn't benefit from heavy feeding. A balanced, slow-release fertilizer (10-10-10 or 5-10-5) applied once in early spring improves healthy growth.

Avoid using excess fertilizer, as this promotes top growth at the expense of blooms. If it has yellowing or weak-looking leaves, a light application of organic compost or liquid seaweed extract will supply nutrients without causing excessive growth stimulation.

Pruning and Cutting Back

Muhly Grass needs to be cut down every year so the old growth is removed, and new, fresh, healthy foliage is encouraged. Pruning is best done in late winter or early spring, just before new growth starts. Snip back the old growth to about 4–6 inches from the ground with sharp garden shears. Irrationally late season pruning, especially late summer to fall, can cut the blooming potential and detour the natural shape of the plant. 

Common Challenges

Muhly Grass requires little care, but a few issues may become evident.

1. Overwatering & Poor Drainage

• Signs: Yellowing leaves, rotting roots, or mold.
• Solution: Make soil drain better, water less often and don’t use heavy clay soil.

2. Weak or No Blooms

• Signs: No pink clouds or limited blossom.
• Causes:
• Too much shade: Relocate to a sunnier spot.
• Over-fertilization: Reduce fertilizer use.
• Late-season pruning: Do not prune after early spring.

3. Overgrowth & Containment Issues

• Solution: Divide oversized clumps in early spring every three to four years to stop overcrowding.
• Muhly Grass is not invasive but can spread if left unattended.

Designing with Muhly Grass in Landscape

Diverse and colorful, Muhly grass is a gorgeous ornamental grass that provides a striking backdrop to any landscape. Its fluffy pink or purple plumes give an airy softness and an ethereal quality that makes this a designer-favorite plant, and it has lots of fans among home gardeners.

1. Using Muhly Grass as a Focal Point

Because of its unique grainy flowers, Muhly Grass can be a striking piece in gardens. Strategically positioned, near entries, along paths, or in garden islands, it catches the eye and adds visual drama.

2. Creating Borders and Edging

This grass acts as a natural edging around garden beds, walkways and driveways. It’s beautiful planted in sharp lines along sidewalks, where it gives us a soft, flowing edge that sways in the breeze. It also pairs nicely with stone pavers, gravel or wood mulch, lending a natural, nonchalant feel to more formal landscapes.

3. Mass Planting for a Bold Statement

Planting Muhly Grass in large groups creates a vivid effect and adds drama to the landscape. Cohorts of these plants blooming together in late summer and fall produce a soft pink plumy wave that can turn any spot into a breathtaking display. This design works best in open landscapes and commercial or public parks, where large-scale planting can give a strong sense of the horticulture employed.

4. Pairing Muhly Grass with Other Plants

The fine, wispy texture of Muhly Grass makes it a great companion plant. It pairs well with:

• Evergreens like Boxwood or Juniper to create contrast with their seasonal blooms.
• Perennials such as Black-Eyed Susans, Echinacea, and Salvia for a colorful blend.
