Sitting in the garden, lamenting the shortening days and the cooling temperatures of September, I was struck by how healthy the koi pond’s watercress was still looking, in spite of the constant gathering of its leaves for soups, salads and sandwiches. Watercress is well known as one of the top superfoods for humans but also as a top water purifier for keepers of koi and other species of fish that require high grade water quality. Watercress is an all-year-round companion plant that can survive without the aid of any soil, it feeds on nitrates which the root system absorbs directly from the water. Water that remains pure because of the absorption of these nitrates.
It initially cost me £3 to buy the three packs of watercress from the supermarket. Barry rigged up a floating raft of soil-free containers linked together and secured to the edge of the pond, a strategy to prevent the large koi, which become very active in the warmer months, from tossing them around. Within days you could see the progress of the rapid growth. All in all, the experiment has been a great success and the plant has earned its keep to remain in the pond. The watercress is healthy and tasty, the fish are bright-coloured and entertaining and I do declare that we are both in fine fettle and hope to remain so for many years.
Now here’s the thing, if your hubby has been trying hard in persuading you to have a fish pond built in the garden, take heed of the above and maybe you too will have your very own superfood at the snip of a pair of scissors.
