All the plants do well in wet meadow conditions, which occur in stormwater ponds during less rainy seasons. The light small rock layer on top of the soil is meant to help the soil layer stay moist during dry seasons. Since the wetland is small and the watershed is small - and water does not necessarily go to the wetland from the roof when it rains - one has to take care of the wetland and water when the weather is hot and dry. (Big wetlands with big watersheds are carefree in this aspect, we did not have a choice of a self-sustaining site). |
