- Check for PestsJune and July40% of varieties
Inspect foliage for aphids or spider mites during hot, dry spells.
Do
- Cut the dead foliage back to the ground once a year in late winter before new shoots emerge.
- Install physical root barriers to restrict the spread of rhizomes in confined garden spaces.
- Plant in areas exposed to salt spray or periodic tidal flooding where other grasses fail.
- Plant in full sun and fast-draining, sandy or gravelly soil
- Cut foliage back to the ground in late winter before spring growth begins
Avoid
- Do not apply fertilizer, as this species is adapted to nutrient-poor soils and excess nutrients weaken the stems.

- Do not shear the foliage frequently during the growing season, which depletes the plant's energy reserves.
- Do not plant in heavy clay or waterlogged soils
What goes wrong with Sporobolus
| Problem | What you'll see | What to do |
|---|---|---|
| Aphids | Clusters of small insects on new shoots causing minor leaf curling. | Knock them off with a strong spray of water from a hose. |
| Grasshoppers | Chewed foliage margins and ragged leaf blades | Apply insecticidal controls designated for grass pests only if defoliation is extensive. |
| Spider Mites | Fine webbing and stippling on the foliage during hot, dry weather. | Increase humidity around the plants or spray with insecticidal soap. |
| Rust | Orange-brown powdery pustules on the leaves in stagnant, non-tidal conditions. | Ensure adequate air circulation and avoid overhead watering. |
| Root Rot | Browning and decay of the root system in stagnant, poorly drained freshwater. | Improve water movement or relocate to a site with tidal flushing or better drainage. |
| Rust fungi | Orange to brown pustules on leaf surfaces | Ensure full sunlight and good air circulation around the plants. |
Making more Sporobolus
Division
- Dig up an established clump in early spring just as new growth begins.
- Slice through the tough rhizomes with a sharp spade to separate the clump into smaller sections.
- Ensure each divided section has several healthy shoots and a strong root system.
- Replant the divisions immediately at the original depth and water thoroughly.
division
- Divide clumps in early spring or fall.
- Plant divisions at the same depth and water thoroughly.
