Does your pond water turn green in summer, its surface covered in duckweed and algal growth? In this clip from Gardeners’ World, Monty Don shows you how to clear the water, both by removing the clogging, slimy strands of silkweed and fast-growing duckweed, and by adding oxygenating plants, including goldfish weed (Lagarosiphon major), hornwort (Ceratophyllum dermensum) and spiked water milfoil (Myriophyllum spicatum). Find out how to prepare the plants, how many to add to your pond, and where to buy them.
