Taming the Mountain Reed: Propagating Merxmuellera macowanii
Merxmuellera macowanii, also known as the Mountain Reed or Cape thatching reed, is a beautiful and versatile grass native to the Drakensberg mountains of South Africa. With its elegant, arching foliage and feathery plumes, it brings a touch of wild grace to gardens and landscapes. But unlike its invasive cousin, pampas grass, this species offers a well-behaved clumping habit that makes it an appealing addition to more restrained planting schemes.
If you’re hoping to introduce this striking grass into your own outdoor space, propagation is key. While Merxmuellera macowanii isn’t commonly found in garden centers, it can be successfully propagated with a bit of patience and the right techniques.
Two Paths to Propagation
1. Division: This method is best suited for established clumps of Merxmuellera macowanii.
* **Timing is Everything:** The ideal time to divide this grass is during its active growing season, which is in spring or early summer. This allows the divided sections ample time to establish themselves before winter dormancy.
* **The Process:** Carefully dig up the entire clump, ensuring you get as much of the root system as possible. Using a sharp, clean spade or knife, divide the clump into smaller sections, each containing a healthy portion of roots and shoots. Replant these divisions at the same depth they were originally growing, water them thoroughly, and mulch around the base to retain moisture.2. Seed: Propagating Merxmuellera macowanii from seed requires a bit more effort, but it can be a rewarding experience, especially if you enjoy the journey from tiny seedling to mature plant.
* **Sourcing Seeds:** These seeds can sometimes be found online from specialist retailers. If you have access to a mature plant, you can also try collecting the seeds yourself once the flowering plumes turn brown and dry.
* **Sowing the Seeds:** These seeds benefit from a period of cold stratification. You can achieve this by either sowing them outdoors in the fall or by mimicking winter conditions in your refrigerator.
* **Outdoor Sowing:** Sow seeds directly into well-drained soil, lightly pressing them into the surface.
* **Refrigerator Stratification:** Wrap the seeds in a damp paper towel, seal them in a plastic bag, and store them in your refrigerator for 4-6 weeks. This simulates the chilling period needed to break their dormancy.
* **After Stratification:** After the cold treatment, plant the seeds in seed trays or pots filled with a well-draining seed-starting mix. Keep the soil consistently moist but not waterlogged. Germination can take anywhere from a few weeks to a couple of months. Essential Care Tips for Successful Propagation
- Well-Drained Soil is Key: Merxmuellera macowanii thrives in soil that drains well. Heavy clay soil can lead to root rot.
- Light Requirements Change: While seedlings benefit from partial shade, established plants prefer full sun to thrive.
- Keep an Eye on Moisture: These grasses are drought-tolerant once established, but consistent watering is crucial for young plants, especially during their first year.
Propagating Merxmuellera macowanii might require a touch of patience, but the process itself is quite straightforward. With a bit of care and attention, you can successfully introduce this captivating grass into your landscape and enjoy its graceful beauty for years to come!
