How to Grow and Care for Mexican Feather Grass

Planting Mexican Feather Grass

To successfully grow Mexican Feather Grass in your garden, it’s important to start on the right foot. Here’s what you need to know:

Selecting the Right Location

Mexican Feather Grass thrives in full sun but can also tolerate partial shade. When selecting the location for planting, make sure it receives at least 6 hours of direct sunlight per day. Additionally, ensure that the soil is well-draining as this grass prefers drier conditions.

Preparing the Soil

Before planting Mexican Feather Grass, it’s crucial to prepare the soil properly. The soil should be loose, well-drained, and rich in organic matter.

You can improve the soil quality by incorporating compost or well-rotted manure. Avoid heavy clay soils as they can retain too much moisture, which may lead to root rot.

Planting Technique

To plant Mexican Feather Grass, start by digging a hole that is slightly larger than the root ball of the plant.

Gently place the grass in the hole, ensuring that the crown of the grass is level with or slightly above the soil surface.

Fill in the hole with soil and lightly tamp it down. Water thoroughly to settle the soil and encourage root establishment.

Watering and Maintenance

Once you’ve planted Mexican Feather Grass, proper watering and maintenance are essential for its long-term health and beauty.

Watering Schedule

Mexican Feather Grass is drought-tolerant once established, but it still requires regular watering during its initial growth phase.

Water deeply once or twice a week during the first few months to encourage root development. After that, you can gradually reduce the frequency of watering to once every two weeks, or even less during rainy periods.


Applying a layer of mulch around the grass can help conserve moisture and suppress weeds. Start by spreading a 2- to 3-inch layer of organic mulch, such as wood chips or straw, around the base of the plant. Be careful not to pile the mulch against the crown of the grass, as this can lead to rotting.

Pruning and Trimming

Mexican Feather Grass is a low-maintenance plant when it comes to pruning. In late winter or early spring, before new growth emerges, trim the grass back to about 6 inches above the ground.

This will remove the dead foliage and encourage fresh growth. Avoid cutting the grass too short, as it may weaken the plant.

Dealing with Pests and Diseases

While Mexican Feather Grass is generally pest and disease-resistant, it may occasionally encounter some common problems. Here’s what you need to watch out for:


Aphids are small, sap-sucking insects that can infest Mexican Feather Grass. If you notice distorted or yellowing leaves, a sticky residue, or ants crawling on the grass, it’s a sign of aphid infestation.

You can control aphids by spraying the grass with a strong jet of water to dislodge them or by using insecticidal soap.


Rust is a fungal disease that can affect Mexican Feather Grass, causing orange or rust-colored spots on the foliage.

To prevent rust, avoid overhead watering and ensure good air circulation around the grass. If rust does occur, prune the affected leaves and dispose of them in the trash to prevent further spread.


If you want to expand your Mexican Feather Grass collection or share it with others, you can propagate it through division. Here’s how:

  1. In early spring, when new growth begins to emerge, carefully dig up the clump of grass.
  2. Divide the clump into smaller sections, ensuring that each division has a good root system.
  3. Replant the divisions in well-prepared soil, following the same planting technique as mentioned earlier.
  4. Water thoroughly and continue to care for the new divisions as you would with mature plants.


Mexican Feather Grass is a stunning addition to any garden or landscape, providing movement, texture, and a touch of elegance.

By following these simple guidelines for planting and care, you can enjoy the beauty of this grass for years to come.

So go ahead, give it a try, and let the Mexican Feather Grass sway in the breeze, adding a touch of natural beauty to your outdoor space.
