Propagation of Panicum autumnale Bosc ex Spreng. var. pubiflorum Vasey ex L. H. Dewey
Panicum autumnale Bosc ex Spreng. var. pubiflorum Vasey ex L. H. Dewey can be propagated through both sexual and asexual means.
Sexual propagation
The plant produces seeds which can be used for sexual propagation. The seeds can be collected from the plant and sown in a suitable container filled with well-draining soil.

The container or planting area should be kept moist until the plant establishes itself.
Cuttings can also be used for asexual propagation. This method involves taking stem cuttings from healthy plants, inserting them into rooting hormone, and then planting them in a suitable container filled with well-draining soil. The container should be kept in a shaded location until the cutting roots. Once roots appear, the container can be moved to a location with bright but indirect light. The cutting should be kept moist until it establishes itself in the container.

The best way to manage rust is to remove any infected leaves immediately and dispose of them properly. This will help prevent the spread of the disease to other parts of the plant.
Another common disease that can affect Fall Panicum is leaf spot. Leaf spot is a fungal disease that presents as small, circular spots on the leaves. These spots can vary in color from dark brown to black and can cause the leaves to yellow and fall prematurely. To manage leaf spot, it is essential to remove any infected leaves and dispose of them immediately. Proper watering and fertilization practices can also help prevent the disease from spreading.
Common Pests
In addition to diseases, Fall Panicum can also be susceptible to various pests. One of the most common pests that can affect this plant is the Fall armyworm.
