All-Natural Algae Control with Barley Straw Extract – Water Garden Q & A

Barley Straw & Barley Straw Extract

Q: I have heard that barley straw will control algae. Is this true? Also I have noticed a product on the market called barley straw extract. Why can’t I just use a bale of barley straw? – Samantha of California

A: Barley Straw has been known for a long time to help in the control of algae. The concept is that as the straw decays, a chemical is released that will reduce algae growth. The problem with using actual Barley Straw is that it takes up to 8 weeks for the straw to decay and begin to work. It also “decays”, which means it puts nutrients back into the pond that will cause future algae growth.

We strongly recommend using an extract (liquid) such as Barley Straw Extract PLUS. The extract is the by product of rotting barley straw. This starts to work on contact instead of having to wait weeks for the straw to decay. It also will not contribute to the nutrient load and is all-natural and safe.

Another great benefit of using the Barley Straw Extract PLUS product is that it contains muck & sludge reducing bacteria.
