Purple moorgrass (Molinia caerulea)
Also known as: Flying bent grass, Purple molinia, Tall purple moor grass, Indian grass
Tufted hairgrass (Deschampsia cespitosa) is a perennial bunchgrass indigenous to Europe, western Asia, and northern Africa. It flourishes in moist, acidic soils and can be found at various elevations. Although it prefers these specific conditions, tufted hairgrass is resilient and can adapt to less optimal environments. Its distinctive tufted appearance makes it easily recognizable.

How to Water Purple moorgrass?
Molinia caerulea prefers a consistently moist but not waterlogged environment. When watering, aim to soak the soil to a depth of about 15 to 20 cm. Ensure the water reaches the root zone but avoid pooling on the surface.

What Is the Ideal Temperature Range for Purple moorgrass?
Molinia caerulea thrives best in temperatures ranging from 60°F to 70°F. This range supports healthy metabolism and growth processes, ensuring vibrant foliage and optimal flowering. Maintaining this temperature range can result in more robust plant health.
What Soil is Best for Purple moorgrass?
Molinia caerulea thrives in nutrient-rich loam soils that provide the perfect balance of drainage and moisture retention. This type of soil supports the plant's growth by ensuring it has a steady supply of essential nutrients for vigorous development and lush foliage. This plant requires soil that retains adequate moisture without becoming waterlogged. The ability to hold moisture promotes consistent hydration, crucial for Molinia caerulea's growth during drier periods. Preferring slightly acidic conditions, Molinia caerulea can absorb nutrients more effectively. This pH range optimizes nutrient availability, promoting healthy root development and a vibrant plant appearance.
How to Fertilize Purple moorgrass?
Molinia caerulea requires a balanced approach to fertilization. During the active growing season, use a liquid fertilizer at a concentration of no more than 1/4 of the recommended dosage. Slowly release fertilizers can be applied sparingly to avoid nutrient burn, ideally around 30 grams per square meter.
How to Prune Purple moorgrass?
Start by cutting back the dead grass clumps to a few inches above ground level. This allows new shoots to get adequate sunlight and encourages healthy regrowth. The best time to prune Molinia caerulea is when the plant is dormant, typically in late winter to early spring. This timing minimizes stress on the plant and encourages vigorous growth in the new season.
How to Propagate Purple moorgrass plant?
1
Ensure the soil is well-draining and enriched with organic matter. This preparation is vital for seed germination and healthy growth, providing the necessary nutrients and moisture retention.
2
Plant the seeds about 1/8 inch deep in moist soil. Cover lightly with soil and keep the surface consistently moist until germination, which typically occurs in a few weeks.
3
Carefully lift established clumps and separate them into smaller sections with a spade. Ensure each section has a healthy root system before replanting immediately.
How to Repot Purple moorgrass plant?
1
Molinia caerulea shows signs of needing repotting when its roots begin to coil around the pot's edges, indicating they need more space. If water drains immediately from the pot, the soil compactness suggests it's time for refreshing.
2
Select a pot that is slightly larger than the current one, with ample drainage holes at the bottom. Terracotta pots are a preferred option due to their breathability, promoting better root health by allowing excess moisture to evaporate.
3
Opt for well-draining loamy soil mixed with some organic matter to provide essential nutrients. This type of soil keeps the roots aerated and prevents waterlogging, a crucial factor in maintaining Molinia caerulea health.
