Fertilization
Andropogon exilis Hochst. doesn't require much fertilizer, but it can benefit from an annual application of a slow-release, balanced fertilizer in the spring. Don't fertilize in the fall, as this can result in new shoots that are too tender to withstand winter.
Pruning
Andropogon exilis Hochst. doesn't require pruning, as it's a grass that forms clumps. You can trim it down to the ground level in early spring before new growth appears to refresh the look. Removing the dead leaves from the plant's base is essential for maintaining its vibrant appearance.
Propagation of Andropogon exilis Hochst.
Andropogon exilis Hochst. is commonly known as the little bluestem grass. This grass species is native to North America, particularly in the eastern United States. It is a warm-season perennial grass that belongs to the Poaceae family. Propagating this plant is relatively easy and can be achieved through two main methods; seed propagation and vegetative propagation.
Seed Propagation
The most common way of propagating Andropogon exilis Hochst. is through seed propagation. This method is easy to perform and cost-effective. The seeds of this plant typically mature in the mid-fall season, around September. To propagate Andropogon exilis Hochst. through seeds, follow the steps below;
- Start by collecting the seeds of the little bluestem plant species. Ensure that the seeds are ripe, healthy, and dry as wet seeds may rot before they germinate.
- Prepare the soil for sowing the seeds. The little bluestem plant species prefers sandy, well-drained soils. Clear the soil of any debris, rocks, or weeds that may hinder the plant's development.
- Sow the seeds into the soil, ensuring that they are adequately covered. Plant the seeds about 1/8 inch deep into the soil.
- Water the soil regularly to keep it moist until the seeds germinate. The germination process typically takes between 14 to 21 days.
- Once the seeds sprout, thin the seedlings to give them enough space to grow. The little bluestem plant species needs a distance of between 6 to 12 inches between plants.
Vegetative Propagation
Vegetative propagation is another method used to propagate Andropogon exilis Hochst. This method involves planting parts of already established plants rather than using seeds. The most common parts that can be used for vegetative propagation include the roots, rhizomes, and stems.
- Start by identifying a healthy Andropogon exilis plant with a well-developed root system, rhizomes, or stems.
- Using a sterilized knife or scissors, cut a section of the plant's root system, rhizomes, or stems. Ensure that the section you cut is healthy and has no diseases, fungus, or pests.
- Prepare the soil for planting the section. The soil should be similar to the soil that the Andropogon exilis plant species prefer, which is sandy and well-drained soil. Dig a hole where you will plant the section.
- Plant the section into the hole and cover it with soil. Ensure that you do not bury the section too deep as this may hinder its growth.
- Water the soil to keep it moist until the section sprouts and develops new growth.
Both seed propagation and vegetative propagation methods can be used to propagate Andropogon exilis Hochst. Choose the propagation method that suits your needs and resources. With proper care and maintenance, you can grow and propagate little bluestem grass plants successfully.
Disease and Pest Management for Andropogon exilis Hochst.
