Aquatic Landscaping: Design, Construction, & Plant Selection for Water Features, Slides of Biology

Bidhan Chandra Krishi Viswavidyalaya Biology

Comprehensive information on aquatic landscaping, covering various aspects such as designing water features, constructing different types of pools, selecting and planting aquatic plants, and maintaining water quality. It offers valuable insights into creating serene and visually appealing water features, from formal to natural designs, and provides tips on positioning, lighting, and materials.

Aquatic landscaping
- Adds serenity or motion
Creating artificial ponds, cascades and waterfalls
Adds visual or auditory impact
Acts as mirror in landscape
Provides habitat for wildlife
Effective for dividing units of landscape
Blue or green lighting makes dramatic effects at night

Designing water features in landscape
- Designs range from formal to natural
- Usually a point of emphasis in landscape
  - Position in low area of landscape where easily viewed
Water gardens need 4-6 hours of light (too much

light will encourage growth of algae)

Or conceal in landscape to create sense of discovery (remainder of landscape must lead viewer to water)
Even-radius curves and straight lines more formal than uneven-radius curves
Cut-stone edges more formal than irregular stone edge

Construction of flexible liner pool
- Liner will snug up against sides of hole when filled
Size, shape and depth determined by hole
Remove rocks and other objects that might puncture lining
Add layer of sand or clay to protect liner
Depth should vary
If including fish, deepest part must >30” or else you’ll make ‘fishsicles’ in winter
Make 9-12” soil benches on perimeter for submerged plants
Cut rocks at edge should also be placed on ‘shelf’

Construction of flexible liner pool
- Size and placement of liner
  - Size formula: 2Depth+Length x 2Depth+Width
  - Liner stretched over hole, keeping taut along bottom
  - Hold liner in place with rocks along edge

Types of aquatic plants
- Submergent
  - Rooted in bottom; leaves remain below the surface of the water
  - Examples: Elodea , Parrot’s feather (invasive)

Types of aquatic plants
- Floating plants
  - Freely float on surface of water
  - Examples: Duckweed, Azolla (fairy moss)

Soil for aquatic plants
- Aquatic plants grow in nutrient-rich soils high in

organic matter

Decomposition of organic matter produce methane-rich substrate (smelly!)
Suggest use of chemical fertilizers
Plants can be rooted into bottom of pond or (more

often) in pots or crates

Use 50-50 mix of garden soil and sand
Plants can be over wintered in cool place inside

Maintaining water quality
- Largest problem with artificial ponds is preventing

algal growth

Incorporate floating plants to shade water surface
Select fish that feed on algae (e.g. grass carp); don’t add too many fish
Use a submerged pump and filter
- Mechanical filters trap debris in mats
- Biological filters use bacteria to breakdown ammonia and organic waste
