My Pampas Grass Flowered For About 4 Years (only 4-5 Plumes Per Year) And Has Not Flowered For The Last 2 Years

How do I get it to start flowering again? Will adding phosphorus to soil help How do I increase the number of plumes? The plumes were dirty white in colour. Can I get pink plumes or is that a different species of pampas grass?

The pink plumes are a different variety of pampas grass (Cortaderia selloana 'Rosea'). Adding a high phosphorous fertilizer such as bone meal will help offset too much nitrogen. These articles should help get yours blooming again:
