Sandy Soils: Add organic matter to improve water retention and nutrient levels.
Acidic Soils: Add lime to raise the pH.

Loosen the Soil: Till or cultivate the soil to a depth of at least 6-8 inches to improve drainage and root growth.

4. Planting Methods: Seeds, Seedlings, or Divisions?

You have several options for planting native grasses:

Seeds: Sowing seeds is the most cost-effective method, especially for large areas. However, it requires patience, as germination can take time. Follow the instructions on the seed packet for planting depth and spacing. Consider broadcasting the seeds or using a seed drill.
Seedlings: Purchasing seedlings from a local nursery is a good option for smaller gardens or if you want a more immediate impact. Plant seedlings at the recommended spacing, ensuring the top of the root ball is level with the soil surface.
Divisions: Established clumps of grasses can be divided in the spring or fall to create new plants. Dig up the clump, divide it into smaller sections, and replant them at the appropriate spacing.

Caring for Your Native Perennial Grasses

Once your native grasses are established, they require relatively little care. However, a few simple practices will help them thrive and reach their full potential.

1. Watering: Finding the Right Balance

Native grasses are drought-tolerant once established, but they still need water, especially during their first year. Water deeply but infrequently, allowing the soil to dry out between waterings. Avoid overwatering, which can lead to root rot.

Newly Planted Grasses: Water regularly, especially during dry periods, until the plants are established.
Established Grasses: Water only during prolonged dry spells.
Watering Technique: Water at the base of the plants to avoid wetting the foliage, which can promote fungal diseases. Soaker hoses or drip irrigation are ideal.

2. Fertilizing: Less is Often More

Native grasses generally don’t require a lot of fertilizer. In fact, excessive fertilization can lead to lush growth that is more susceptible to disease and less resilient to environmental stresses. If you decide to fertilize, use a slow-release, low-nitrogen fertilizer in the spring. A soil test will help you determine if fertilization is necessary.

3. Weeding: Keeping the Competition at Bay

Weeds can compete with native grasses for resources like water, nutrients, and sunlight. Regularly remove weeds, especially during the first year or two, to give your grasses a head start. Mulching can help suppress weeds and conserve moisture.

4. Mulching: Providing Protection and Benefits

Mulching offers numerous benefits for native grasses, including:

Weed suppression
Moisture retention
Temperature regulation
Soil enrichment (as the mulch decomposes)

Use organic mulches like wood chips, shredded bark, or straw. Apply a layer of 2-4 inches, keeping the mulch away from the base of the grass clumps.

5. Pruning: Shaping and Maintaining Your Grasses

Pruning native grasses helps maintain their shape, remove dead foliage, and encourage new growth. The timing and method of pruning depend on the species and your aesthetic preferences.

Cool-Season Grasses: Prune these grasses in late winter or early spring, before new growth emerges. Cut them back to within a few inches of the ground.
Warm-Season Grasses: Prune these grasses in late winter or early spring, before new growth emerges. Cut them back to within a few inches of the ground.
Evergreen Grasses: These grasses generally don’t need to be cut back. Simply remove any dead or damaged foliage.
