Andropogon grass, commonly known as big bluestem, is a popular native grass used in landscaping and restoration projects. Properly dividing this grass can help maintain its health and vigor without causing stress or damage. In this article, we explore the best practices for dividing Andropogon grass effectively.
Understanding When to Divide
The optimal time to divide Andropogon grass is during its dormant season, typically in late winter or early spring before new growth begins. Dividing during this period minimizes stress and allows the grass to establish quickly after division.
Tools Needed for Division
- Sharp garden spade or shovel
- Garden knife or sickle
- Pruning shears
- Gloves
- Water source for soaking
Step-by-Step Division Process
Follow these steps to divide Andropogon grass successfully:
1. Prepare the Plant
Water the grass thoroughly a day before dividing to soften the soil and reduce stress during removal.
2. Dig Around the Clump
Use a sharp spade or shovel to carefully dig around the base of the clump, creating a wide circle to loosen the root ball.
3. Lift and Divide
Gently lift the entire clump from the ground. Use a garden knife or sickle to divide the root ball into smaller sections, each with healthy roots and shoots.
4. Trim and Prepare Divisions
Trim any damaged roots and leaves to encourage healthy growth. Ensure each division has at least one healthy shoot.
Post-Division Care
After dividing, plant each section at the same depth as the original. Water thoroughly to settle the soil and reduce transplant shock. Mulching around the divisions helps retain moisture and suppress weeds.
Tips for Minimizing Stress
- Avoid dividing during extreme heat or drought conditions.
- Use sharp tools to minimize root damage.
- Ensure proper watering after division.
- Maintain consistent soil moisture during establishment.
By following these best practices, you can successfully divide Andropogon grass without causing undue stress, ensuring healthy growth and vibrant landscapes.
