Common problems with water gardens.

There are several problems that may develop when you install a water garden.  The most common problem is soil composition.  It is important to make sure that the soil is amended properly so that water is able to percolate through the soil.  Clay is a dense material and does not percolate well at all.  Amending your soil with a mixture of sand and compost will help create the perfect soil composition.  It is usually recommended that you use a 50% sand to 50% soil and compost mix.  The more sand content, the quicker that the water is filtered through the water garden.

When installing plant material, it is important choose plants that will thrive in the newly created environment.  Some plants are more sensitive than others.  Make sure that you choose the best plants for the soil conditions as well as the water conditions.  Keep in mind anytime you install a new plant, it will take a time for the plant to adequately root in.  If your water garden experiences heavy rain right after your planting, you may have some of your plants wash away.
