Rubrum – Purple Fountain Grass

Anonymous added on September 22, 2015 | Answered

I have Rubrum in planters in my home. My cats love to eat it. Do I prune it in late winter as if it was outside? Also, do I keep watering it if I do prune it? Thanks for your help.

Clip the foliage down to about 3 inches from the top of the pot and water well. Then refrain from watering except once a month over winter to prevent the plant from becoming too dry. Once warmer temps return in spring, return it outdoors and give it a boost of fertilizer to stimulate new growth.
