Winterizing Water Gardens
Naturalized water gardens that may include a waterfall, stream and/or pond, add such an incredible creative touch to your landscaping. Working in harmony with nature they offer a sanctuary for your senses. Astonishingly, they require little maintenance. Periodic cleaning out the skimmer of leaves and adding beneficial bacteria is essentially the extent of regular care. It is important to maintain clear, clean water and to do this without the use of unsightly and costly filtration systems and chemicals. Water gardens should be naturally self-regulating ecosystems requiring significantly less maintenance than if the area were planted in grass. However, like most everything you need to prepare your special sanctuary for the winter.
The cool weather of autumn brings on noticeable changes in a water garden. As long as fish feed, they will continue to produce waste. Dying aquatic vegetation that is not removed from the pond adds to the organic load. The fact that aquatic plants are entering dormancy allows for increased nitrate availability. This means an increased growth of filamentous, string algae, that slimy stuff. No need to be alarmed. The ecosystem is still healthy. This is considered normal transition. Where the sunlight penetration is high on your water garden in shallow streams and pools, the algae will increase the most. This is to be expected. Cold doesn’t bother the algae. (more…)
