Learn how to create a bog garden in containers with this gardening tutorial. There are some lovely plants for growing in damp, boggy conditions, but if your soil is well drained and dries out quickly these bog plants will struggle to grow. A simple way of growing bog plants is in a large container such as a half barrel that has no drainage holes in the base. The barrel when wet will seal and hold water very well keeping the compost moist at all times. What you may need to do if the barrel is completely water tight is drill a few small holes through the sides half way up the barrel to allow excess water to drain out slowly.
