Is there anything I can feed Pink Pampas Grass to get more reddish plumes?

Question

Eight plants are in a line spaced about 4′ apart and the flowerbed is rich with chicken manure compost and sphagnum moss which normally grows ANYTHING.

Answer 1

You will not be able to change your pink pampas grass to a red color.

You may see different shades of the original pink plant color, depending on light and growing conditions.
