Building a bog garden with the Boiling Spring Lakes Garden Club

So I had the unique opportunity to help the Boiling Spring Lakes Garden Club build a bog garden for carnivorous plants.  The bog garden is situated behind the Boiling Spring Lakes Community Center next to the butterfly garden.  It will give the community the opportunity to see carnivorous plants like the Venus flytrap in a convenient location; no hiking required!

Here is our step by step construction of the bog garden:

First we measured and planned out the shape of the garden and broke ground!  We chose an 8’X5′ kidney bean-shaped garden.

Once the shape and size were planned out we dug the entire garden 2′ deep and lined the entire thing with old carpet to prevent roots from breaking into the garden.

Next we lined the garden with a 12mm pond liner and secured it with some rocks.

Once the liner was secure we filled the garden with 1′ of sand.  We used some of the natural sand that we dug out of the garden initially and mixed it with coarse contractors sand for better water permeability.

A bog garden is designed to hold moisture and be wet, like a natural bog, so after we put the 1′ of sand in the hole we dampened it with well water.  It is very important to use a natural source of water because the chemicals in municipal water are toxic to the bog garden.

The final step is to fill in the remainder of the garden with a peat sand mixture.  We mixed the peat/sand 3:1 and filled in the garden!

Voila!!  We watered the peat with well water until it was squishy and the garden will sit for a couple of days and settle.  The edges of the garden will be finished with a layer of sand, a layer of mulch and the rocks.  In a few weeks we will plant it with Venus flytraps, butterworts, pitcher plants, and native grasses!

The bog garden construction materials were provided by the garden club and the plants will be provided by the North Carolina Botanical Garden.
