Aquatic Information

Information Sheets!

A water garden, whether it be a water-proof container on the patio, a half-barrel with a fountain or an in-ground pond, can bring the sights and sounds usually found near lakes or streams right into your own backyard.  Deneweth's Garden Center carries a selection of Aquatic Plants to fit your Water Garden needs.  

Living in the heart of the city, we often miss out on the simple pleasures that come from living near water.

Where to put a water garden?

 Choose the site carefully, using this checklist:

1. Sun/Shade – Most water lilies need full sun to bloom well.

2. Leaves/Litter – Leaves and other organic matter decay into sludge in a pond.

3. Drainage – Choose a level or raised site, not a low-lying area.

4. Utilities – A spigot for filling, and an outdoor electrical outlet.

5. Fountains or Waterfalls – Provides much needed aeration.

6. Fish – Fish can be wonderful pets in a good-sized pond.

 Plants for Ponds

 Water Lilies – Water Lilies come in many colors and styles.  The flowers are usually double, often fragrant, from 2 to 10 inches wide.

 Floating Plants – Water Lettuce (Pistia stratiotes) forms rosettes of ribbed leaves.  Water hyacinth (Eichhornia crassipes) bears spikes of showy violet flowers.  Both plants float on the surface and do not need to be potted.  Floating plants are not hardy to Zone 5.

 Oxygenating Plants – Also called submerged plants, these grow underwater, although their leaves may float to the surface.  They filter and clear the water, release oxygen, and provide food and shelter for fish.

 Marginal Plants – Marginal, or emergent plants live in the wet soil or shallow water around the edge of a pool.  This group of plants can include hardy and tropical perennials, grasses and ferns.

 Fish

Ornamental Fish –  The most common ornamental fish are goldfish and koi; both have long histories of being bred for their exotic features and beautiful vibrant colors.  Koi can withstand a wide range of temperatures.  Koi can survive under the ice in extreme cold as long as the water does not freeze solid.
