So if you read any Cool Ponds articles, newsletters, postcards, etc. you know that as of July 23, 2016 we have a new "Serenity Garden" here. We've plugged it pretty hard. The photo above shows the bog area of the pond surrounded by water lilies both hardy and tropical. What's great about this bog is not only is it awesome aesthetically and helping to keep the pond clean... it's also now home to two frogs.
They must have moved in almost as soon as the pond was finished. I guess they like the "serenity" of the garden as well. Can you see the bullfrog in the photo above? Check out the close up below:
They love the bog because they can float in among the aquatic plants and be pretty much unnoticeable. Honestly I wouldn't have seen them if Kasey hadn't pointed them out! (There is actually a Leopard Frog behind the boulder sticking out of the water in the top photo it's just not visible.) Plus there's an unlimited supply of little insects for them to eat. We have frogs all over the place here at our shop and we can pretty much attribute that to the heavy plant cover in all our water features.
If you are looking to entice some frogs to live in and enjoy your pond, I recommend creating a bog area. What is a bog? It's a shallow area that's filled with marginal aquatic plants. All of our ponds here at the store have some type of bog area -- some of them multiple bogs. Marginal plants are those that have their roots in the water but the foliage is above the water surface.
It's not difficult to create a bog on an existing pond.
Option 1: Build a little retaining area with boulders inside the pond and fill the area with river rock to 1-2" below the water surface. You might be able to expand an existing shelf, possibly? The key is that it needs to be shallow.
Option 2: (More advanced.) Dig a shallow area next to your pond and attach new liner to create the bog area. Fill the new area with river rock.
For me the critters that live in my pond are what I enjoy most. Anything I can do to make them feel more at home and safe is a project well worth it!
