Title: Grasses for dry bottom detention ponds
Answered by: Nan Hampton

QUESTION:

I am working on a project for my HOA in order to reduce mowing costs and to beautify our neighborhood. We were wondering if you could help us find people knowledgeable about dry bottom detention ponds and grasses that could be used that were slow growing, required little fertilizer but could have a strong enough root structure to maintain the slopes of a detention pond(s). We are located in Pearland, TX

ANSWER:

Please see our National Suppliers Directory for information about Landscape Professionals and Environmental Consultants in your area who might be knowledgeable about dry bottom detention ponds.

Grasses are excellent plants for stabilizing slopes because of their extensive fibrous root systems and native grasses require no, or very little, fertilizer. If the detention pond is in a primarily sunny area, then an excellent choice for a grass is Bouteloua dactyloides (buffalograss) since it grows slowly and doesn't require frequent mowing. However, it will not deal well with standing water which may happen with your detention pond. You would probably be better off with plants that are appropriate to a raingarden situation—plants that tolerate standing in water but can also thrive when the water dries up completely. Sedges (such as Carex blanda (eastern woodland sedge), Carex cherokeensis (Cherokee sedge) or Carex texensis (Texas sedge)) are grasslike, don't grow too tall, and can withstand both wet and dry situations.

You might also consider ornamental grasses that are pleasing to look at without needing to be mowed, for instance:

Andropogon glomeratus (bushy bluestem), Chasmanthium latifolium (Inland sea oats), and Muhlenbergia capillaris (Gulf muhly).
