How to grow it: Kang Kong is a terrifically hardy perennial that will grow anywhere at anytime it’s growing conditions are met – that is, when it’s hot & wet. It grows like mad in these conditions, and will meander or die back when it’s cold and/or dry. Seems just as happy in sun or shade

In the tropics, it will grow all year if it has regular water, but is best planted as the wet season begins and will require no maintenance. If there’s a problem with it, it can get out of control – a great reason to harvest it regularly.
In cooler areas, it will die back in winter and reshoot in spring. In cold areas it’s growing season might be quite short.

Given it’s water requirements, it does best in a boggy area or on the edges of ponds. It’s just as happy in shallow water as it is in wet mud. It does well in a shadehouse or hothouse and it’s growing period might be extended due to the extra warmth.
Kang Kong will certainly benefit from the addition of manure, compost, worm juice or seaweed, but will also do pretty well without any maintenance at all. Once I put a cutting in a vase of water to root, and it grew & produced leaves for months without any help at all – quite amazing!

I’ve had great success growing Kang Kong in closed containers – simply fill any closed container (20 litre bucket, pots with no drainage, styrofoam boxes etc) with soil leaving 5-10 cms from the top. Fill with water to a level just above the soil, and put your cuttings or seeds in. As soon as the plants start growing you can start harvesting. This growing method can be very productive and is great for drier climates – just add a bit a bit of water when needed – the foliage will reduce much of the water loss.
