Green Water: How to Treat a Pond with Barley Straw
Barley straw is a cheap and effective way of keeping a pond clear of algae the natural way. Barley straw is completely natural and safe, and will inhibit algae growth without any risk to wildlife or plants.
Treating a pond with Barley Straw bales is simple and easy - all you need to do is throw them into the pond. As the barley straw breaks down and rots, it releases compounds which stop algae and blanket weed growth.
Barley straw will typically break down during the warmer temperatures of spring and summer in around 2 weeks. In colder temperatures throughout autumn and winter, it can take 3-4 weeks. After this time, new algae growth will be prevented and your pond water should start to clear.
Once added, barley straw will continue working for around 3-4 months while it rots. It is recommended that new bales are added around 3 months after the initial batch, to continue to inhibit the growth of algae.
