Eastern gamagrass plants are native to the eastern U.S. and can grow as tall as eight feet (2 m.) high. Although once prevalent across eastern states, European settlers allowed animals to overgraze gamagrass and it is now rare to find it in natural settings. As a grass for forage or hay, it is highly productive and easy to grow. 

About Eastern Gamagrass

Tripsacum dactyloides, or eastern gamagrass, is a native perennial. It is a warm season bunch grass that grows well in soil that is well-drained but also in poor-draining soils. It is well-adapted to wetter areas and can tolerate flooding. 

Among native grasses, gamagrass is one of the most productive. It is an excellent grass to grow if you have livestock needing summer forage. It is also a good option to make hay. Overgrazing destroys gamagrass quickly, though, so make sure you rotate it and when cutting to make hay, leave six to eight inches (15-20 cm.). 

When to Plant Gamagrass

Gamagrass is often planted with corn between the rows. This can provide a good guide for when to plant gamagrass. Start the seeds during early corn planting with the corn first, followed by gamagrass. Generally, you’ll be planting in the spring and the soil should have reached 55 degrees F. (13 C.)

How to Plant Eastern Gamagrass

Germination of eastern gamagrass seed can fail if you skip the stratification process. This means wet-chilling the seeds at about 35 degrees F. (2 C.) for several weeks before planting. You can also buy seeds that are already stratified. Plant the seeds in prepared soil and at a density of about ten pounds of seeds per acre. 

When planting eastern gamagrass, weed control is important. Pre-emergent weed treatments, or planting with corn and other grasses, can help manage weeds. After one year of successful growth with the gamagrass established, weeds shouldn’t be a problem. 

Also avoid harvesting any of the grass until one year of good growth. Also be sure that you rotate livestock if using gamagrass as forage. Rotational stocking will ensure that the grass is not overgrazed.
