marantaceae question

honugirlhawaiiOctober 31, 2011

I have a bed of stromanthe tri-color, marantaceae. After four years of hardy growth, the stems of the leaves are no longer erect and the center of the plant is exposed. I'm thinking that I may need to dig them up and replant them. Is there an easier way to bring them back to full foliage?

Do Stromanthes grow fast in Hawaii?

Other than repotting, you can prune stems; they should regrow compact. Toni

I think I'm reading you to say these are in the ground. It's common for clump growers to lose vitality at the center of the clump to the point where the center dies out entirely. Grasses do this as well. It's your signal that they need dividing. The reason is the root mass in the center of the clump is soo congested the plants growing there are unable to take up water or nutrients.

Dig up the clump. Chop it apart with a sharp spade, ax, adz ....., and replant. Use plants from the outer edges of the clump as they will be most vigorous.

Aloha Al and Toni,
Oops. I realized after submitting my question, that I was in the wrong forum.
My plants are in the ground and not potted. Al, you've given me an explanation for the condition of my stromanthe. I will divide and replant this weekend. Your information saved my plants!
Mahalo,
Sharon
