Rice and Taro are amongst the earliest water plants in cultivation. Around the world people cultivate edible aquatic plants, as well as aquatic animals including fish and crays. The farming of these is called aquaculture or aquafarming. Aquaponics intergrates both aquatic plant farming with the production of fish.
Sustainable gardens
This is a popular trend in gardens that strives to minimise our impacts on the environment, through the demands that we place on available water, as well as the materials and energy we use in the garden. Even small scale environmentally friendly gardens, that support the diverse nature around us, can play an important role in reducing the environmental impacts of large scale commercial food production.
Good to eat and good to look at....
Edible aquatic plants need not only be selected for their crop. At Oz Watergardens we focus on their ornamental appearance as well. Why not have edible aquatic plants that are both beautiful to look at, but also produce healthy food?
Edible aquatic plants are easy to grow If you love growing your own healthy food, but have limited space, aquatic pots are just as easy to maintain as regular edible herbs. Just keep the water topped up.
Miniature water gardens producing edible aquatic plants can be made in almost any container that can hold water, even a sealed window planter box. A bucket kept in a sunny position can produce a kilogram of water chestnuts in one growing season. If you have a little more space consider an old bath tub capable of producing 30-40kg of delicious water chestnuts in a single growing season.
Growing Mix For most edible water garden production, we recommend using approximately 1/3 compost mixed with a clay- loam soil. However, for root -type or tuberous edible aquatic plants, we suggest a sandy-loam soil. Although the plants will grow successfully in other soils, we find that it is easier to wash off the sandy loam than a heavy clay soil.
Growing conditions for edible aquatic plants Most edible aquatic plants come from tropical or sub-tropical climates. Many can be grown in cooler climates, but best results are achieved if you can grow them in warm sheltered positions.
Do not grow edible aquatic plants using untreated grey water. Although they are often excellent water filtering plants, they may also absorb many heavy metals and toxins that may be harmful in your diet.
