The Lawn Whisperer’s Secret: Propagating Carpetgrass (Axonopus capillaris)
Carpetgrass (Axonopus capillaris), with its fine texture and rapid growth, is a popular choice for lawns, particularly in warmer climates. While you can establish a new carpetgrass lawn with sod, propagating it yourself can be a cost-effective and rewarding alternative.
This guide explores the different methods to propagate carpetgrass, empowering you to cultivate a lush and vibrant lawn without breaking the bank:
1. Propagation by Seed:
- Timing is Key: Sow carpetgrass seeds in late spring or early summer when the soil temperature is consistently warm (around 70°F or 21°C).
- Prepare the Stage: Loosen the top few inches of soil and remove any existing weeds. Carpetgrass thrives in slightly acidic soil, so amending with compost can enhance its growth.
- Sowing the Seeds: Scatter the seeds evenly over the prepared area, aiming for a rate of 5-8 pounds per 1000 square feet. Lightly rake the seeds into the soil, ensuring good contact.
- Patience, Young Grasshopper: Keep the soil consistently moist but not waterlogged. Germination typically takes 10-21 days.
- First Mowing Matters: Wait until the grass reaches about 3 inches tall before the first mowing.
2. Propagation by Plugs:
- Plugs: The Instant Gratification Option: Plugs are small squares of established grass, offering quicker coverage than seeds.
- Spacing and Planting: Plant plugs 6-12 inches apart in a grid pattern. Ensure the top of the plug is level with the soil surface.
- Water Wisely: Water the plugs thoroughly after planting and keep the soil consistently moist until they are well-established.
3. Propagation by Sprigging:
- Sprigging: A Less Common, But Effective Method: Sprigging involves planting sections of stolons (horizontal stems) or rhizomes (underground stems) to establish new plants.
- Selection is Crucial: Choose healthy, mature stolons or rhizomes from an existing carpetgrass lawn.
- Planting Technique: Plant the sprigs 6-12 inches apart, ensuring at least one node (where roots emerge) is below the soil surface.
- Patience is Key: Keep the area consistently moist. It may take several weeks for the sprigs to root and new growth to appear.
Tips for Successful Carpetgrass Propagation:
- Sun Worshipper: Carpetgrass prefers full sun to partial shade (at least 4 hours of direct sunlight daily).
- Mowing Maintenance: Mow your carpetgrass lawn regularly, maintaining a height of 1.5-2.5 inches.
- Nutrition is Key: Fertilize your carpetgrass lawn in spring and early summer with a balanced fertilizer to support healthy growth.
Conclusion:
Propagating carpetgrass might seem daunting at first, but with patience and the right approach, you can achieve a lush and beautiful lawn. Whether you choose seeds, plugs, or sprigs, the satisfaction of cultivating your own lawn is truly rewarding. Now, put on your gardening gloves and get ready to grow a carpetgrass lawn that’s the envy of the neighborhood!
