Choose the right location and size for your water garden.

Before you start digging, it's important to choose the right location and size for your edible water garden. Look for a spot in your yard that gets at least six hours of sunlight per day and has access to a water source. Consider the size of your garden based on the amount of space you have available and the types of plants you want to grow. Keep in mind that larger gardens will require more maintenance and may be more difficult to manage.

Select the right plants for your water garden.

Water Garlic is a fairly recent addition to the world of pond plants.

4. Vietnamese Water Mint (Polygonium odoratum)

Vietnamese Water Mint (Polygonium odoratum) pot with floating ring

Vietnamese Water Mint also known as Vietnamese coriander is one of the most useful and easy to grow water plants. It is an exceptionally fast grower, and its leaves can be used in drinks, salads and curries. Aside from their edible qualities, the leaves have an almost dark variegated pattern on them, and they are very attractive. Although not a true member of the mint family of plants it carries many of the same traits in how it grows, reproduces, and tastes.  

It can grow up to 30cm in size, but when used on a floating ring on the pond, Vietnamese Water mint tends to spread out rather then grow up right.  It can be propagated from cuttings with the stems of the plant dropping roots in the water as it spills into the pond. A fast grower, Vietnamese Water Mint needs monthly feeding using a pond fertiliser tablet from October through to March.  As well as the leaves being edible, when grown in the floating ring that comes with all of our plants it spreads out and provides shelter for fish and tadpoles.


5. Water parsley (Oenanthe sarmentosa)

Incorporate fish and other aquatic life into your water garden.

The waste produced by your fish will be taken up as nutrient by your edible plants, a classic example of aquaponics in action!

Be sure to research the specific needs of each species and provide appropriate filtration and aeration to keep the water clean and oxygenated. Additionally, consider adding beneficial bacteria to help break down waste and maintain a healthy balance in the water.

Maintain proper water quality and circulation.
