Pink pampas grass is an ornamental grass with an upright, fountain-like appearance. This grass is perennial in U.S. Department of Agriculture plant hardiness zones 5 to 11. Pink pampas grass reaches 8 to 10 feet in height and width. The large pink feathery plumes on the female pampas plants can reach 20 feet tall in the summer and fall. Pink pampas grass is grown as a specimen plant, and as barriers, windbreaks, borders and for cut flowers.
Work the soil with a shovel in an area that is partially in the shade. Dig a hole as deep as the pampas grass root ball and place the plant in the soil. Firm the soil around the plant and water well. Plant other pink pampas grass 36 to 60 inches apart.
Water each week when there is no rainfall. Pink pampas grass is tolerant of arid conditions. Run water on the ground around the plant for 10 to 15 minutes each time you water.
Cut the pink pampas grass back in the late winter (February to March) to the height of 1 foot. This removes last year’s foliage and makes room for next season’s new growth, according to University of Georgia Extension. Prune the pink pampas grass with sharp hedge shears.
Sprinkle 8-8-8 or 10-10-10 (nitrogen-phosphorus-potassium) slow-release fertilizer around the pink pampas grass at the rate of 1 to 2 pounds per 100 square feet of planting area. Scratch the fertilizer in with a rake and water the area to stimulate new growth.
Harvest the pink flower plumes right after they fully emerge, but before they start shedding. Once the harvested plumes are dry, University of Georgia Extension recommends spraying them with hair spray to prevent the loss of the feathery blossoms.
Split off sections of the outside edge of the mother pink pampas grass with a shovel in the fall when you want more plants. Leave the mother plant in the original spot and replant the small clumps in a new site or in containers. If the center of the pink pampas grass dies, slit off the outer plants and replace the mother plant with a younger plant.
