Title: Retention pond from Hendersonville NC
Answered by: Barbara Medford
QUESTION:
We have a retention pond that has recently been cleaned and we would like to plant perennial native plant and grass seeds that will enhance the appearance and contribute to the natural process of filtration, hold the soil when water is rushing by and permit pollutants in the water to be filtered out. What time of the year should the seed be planted and able to stand generally wet feet?ANSWER:
From the EPA, here is an article on National Pollutant Discharge Elimination System, which is about retention ponds.
With that in mind, we have two very similar questions in our queue; one is yours from North Carolina and another is from Michigan. We suggest you read the Michigan answers for some background information:
We found a previous Mr. Smarty Plants question originating from Virginia which we think might have some information of use to you. There are some more links to further information in that, and instructions on using our Native Plant Database. Since we don't know if you want all grasses, how moist your soils are, how much sunlight they will get, etc, we think it would be better if you made your own plant list. Native grasses are certainly the best choice as their long fibrous roots will definitely help to hold the soil. As for the time the seeds should be planted (or plants if you are putting in some shrubs) is dependant on the part of the country. In Texas, we recommend planting grass seeds in mid-April, and hoping for gentle consistent rains, which we seldom get. If you go down the webpage on each plant you are investigating to the bottom you will see a list of Additional Resources. Click on "Search Google for ______ (plant name). Sometimes the webpage will have specific Propagation Instructions on it.
