If you don’t have space for a full-size bog, creating a container bog garden is easily done. Even small potted bog gardens will hold an array of colorful, fascinating plants. Let’s get started.
Creating a Container Bog Garden
To make your bog garden in a container, start with something measuring at least 12 inches (31 cm.) deep and 8 inches (20 cm.) across or larger. Any container that holds water will work, but keep in mind that larger bog garden planters won’t dry out as quickly. If you have space, a pond liner or children’s wading pool works well. (The container should not have a drainage hole.) Create a substrate by filling the bottom one-third of the container with pea gravel or coarse builder’s sand. Make a potting mix consisting of approximately one-part builder’s sand and two parts peat moss. If possible, mix the peat moss with a few handfuls of long-fibered sphagnum moss. Put the potting mix on top of the substrate. The layer of potting mix should be at least 6 to 8 inches (15-20 cm.) deep. Water well to saturate the potting mix. Let the potted bog garden sit for at least a week, which allows the peat to absorb the water, and ensures the pH level of the bog has time to balance. Put your bog garden where it receives the proper amount of light for the plants you have chosen. Most bog plants thrive in an open area with plenty of sunlight. Your bog garden in a pot is ready to plant. Once planted, surround the plants with live moss, which promotes a healthy environment, prevents the bog from drying out quickly, and camouflages the edges of the container. Check the bog garden planter daily and add water if dry. Tap water is fine, but rainwater is even better. Watch for flooding during rainy periods.
