Water Garden definition

– A pool of water, larger or miniature where aquatic plants are grown for beautification is called a water garden.

– Many beautiful and unusual plants can be grown in a water garden which bloom on the shining surface and add great charm to a garden.

– Water can add greatly to the beauty of most gardens, particularly if it is skillfully employed and used in such a manner as to permit the introduction of aquatic and moisture loving plants.

– Water in a small garden furnishes a cooling, refreshing surface during hot summer days, duplicating and enhancing the beauty of nearby trees, shrubs and flowers.

– At night it will reflect the moon, multiply the stars and create a pulsating feeling of life in the middle of the deadening effect of darkness.

Making a water garden

How to Build a Water Garden with Different Pools


The garden should be located under open sun. Therefore, the pool should be constructed to some distances from tree or hedges so that dead leaves do not fall into the pool and foul the water.


Water gardens are either formal or informal.

– Formal pools look better in conventional surroundings and do not blend with natural features such as wild gardens and rock gardens.

– The vegetation in them is kept low, concentrating on water lilies, submerged and aquatics.

– An informal pool should not disclose its construction. The concrete or other material of which it is made can be hidden by keeping the outer edges below the level of surrounding ground and by the skillful use of bog and marginal aquatics to bridge the gap between the water and dry land.

– The water garden should be smaller than normal ponds. Water level should be maintained artificially by establishing inlets and outlets in the garden.

Types of pools

-There are four types of pool for construction –ac

i) Concrete pool

– These are the most popular pools and may be of any size and shape. If properly constructed, they last for many years.

– A concrete pool need not be the same depth all over. Water lilies and submerged oxygen producers are mainly used here.

ii) Prefabricated pools

– These pools are made of fiberglass and are available in all shapes and sizes ( 2.5 – 3.5m most commonly ). To install, simply excavate a hole into which the pool just fits, level the rim, set the plants and fill with water.

– The edges are usually concealed by turf, creeping plants, rocks etc.

iii) Polythene sheeting

– This is an inexpensive and simple method of preparing a site for growing aquatics.

– But there are two main disadvantages, a) A stab with a fork or similar sharp tools spells disaster and b) If hot sun constantly plays on the material above the water line, it is likely to disintegrate and leak when the pool is full.

iv) Miscellaneous containers

– Tubs, old bath tubs, stone troughs and even galvanized tanks can be used for        water gardens.

– They are just sunk under the ground and all the leaks should be plugged before putting water.

– Such pools are normally very small and contain only a few water plants.

–  Of these four types, well prepared concrete pool is probably the best.

Construction of the pool

– The construction of a small lily pool is well within the scope of any handyman.

– The real secret of success is to work with really fresh cement and to prepare the concrete with just enough but not too much water.

– The exposed rim of the pool looks best if it is 45 – 60cm or 1m wide and made of stone, bricks or blocks of concrete paving.

– The bottom layer of concrete should not be less than 10cm in thickness even in small layers of pools and the sides will have the same thickness as at the base.

– Volumetrically, 3 parts washed gravel, 1 part builder’s sand and 1 part cement will give the right proportion for making the concrete pool.

Depth of a pool

– The pool should not be very deep. Too much depth is disadvantageous and it is preferable to have 1.25 – 1.5m depth.

– According to their types water lilies need 45cm – 1m of water above earth level in the pool.


– Fairly heavy loam or clay loam soil is the best for proper growth and development of the majority of the water plants like water lilies and lotuses.

– Organic materials normally should not be added into the pools. During their break down they will change the water with mineral salts. These will encourage algae to grow, which in turn will discolor the water.

– If too much organic matter is present, putrid gases escape and can suffocate fishes.

Methods of growing water lilies

– There are two methods of growing water lilies in the artificial pools.

– One is to place a 12 – 15cm thick carpet of prepared soil over the bottom of the empty pool and plant corms of water lily directly into this material, later covering the bed with 3 – 6cm of sand or gravel before running in water.

– The second method is to plant water lilies directly into containers with several holes on the side or base. Stones are put on the upper surface of the container and the whole container is then dipped into the water.

– The best time for planting lilies is the spring i.e., late April or May to June when many aquatics just start to grow.

Care and management

– During the period of growth all old and dead leaves and maturing flowers should be removed.

– Algae may be destroyed by scattering copper sulfate over the surface @ 15g to every 125cft of water.

– From time to time, small pools need to be emptied and replanted with fresh soil,  chiefly because the lilies exhaust the soil and the flowers become fewer and smaller.

Recommended plants for water garden

– The following plants may be recommended for planting in the water garden –

  1. a) Water lily, Lotuses, Sweet flag, Water plantain, caltha
  2. b) Floating plants: Water hyacinth, Water lettuce, Water chestnut
  3. c) Plants for bank of the pool: Bamboo, Canna, Ferns, Ground lilies, Flowering grass
