The ideal planting time for Panicum dichotomiflorum Michx. var. bartowense (Scribn. & Merr.) Fern. is in late spring or early summer when the soil has warmed up. Sow the seeds at a depth of 1/8 to 1/4 inches and ensure that they are evenly distributed. When planting, leave enough space between seeds or rows to establish healthy growth.
The grass should be kept moist until seeds germinate, which typically takes between 7-14 days. Once the grass is established, it is relatively low maintenance and can thrive in various environments.
Watering Needs
Although Panicum dichotomiflorum Michx. var. bartowense (Scribn. & Merr.) Fern. is relatively easy to maintain, proper watering is necessary for healthy growth throughout the growing season. The grass is drought-resistant once established, but regular watering is still required to ensure the soil stays moist.
A deep and thorough watering every week is necessary for the first couple of weeks after planting to encourage root development. After that, the plant should receive an inch of water every week, either from rainfall or irrigation. Pay attention to the soil and the grass to ensure it does not become oversaturated, as this can cause root rot and pest infestations.
Fertilization
Panicum dichotomiflorum Michx. var. bartowense (Scribn. & Merr.) Fern. requires proper feeding to encourage healthy growth and development. The grass requires nitrogen and other essential nutrients to thrive.
Use a slow-release fertilizer every year during the growing season, preferably in early spring or late winter. Apply the fertilizer based on the manufacturer's recommendations and ensure it is evenly distributed across the lawn. Repeat the application every six to eight weeks throughout the growing season for optimal results. However, always ensure you read the application instructions and use the fertilizer as recommended.
Pruning
Panicum dichotomiflorum Michx. var. bartowense (Scribn. & Merr.) Fern. requires little to no pruning apart from removing dead or damaged leaves or stems. If the grass grows too tall or becomes overcrowded, use a lawn mower to mow it down to two to three inches in height. Be careful not to scalp the lawn, as this can damage the root system.
Mowing should be done every two to three weeks throughout the growing season or as needed to keep the grass at an appropriate height. When mowing, ensure that the blades are sharp to prevent damage to the grass.
