The bags of barley simply float on the top of your pond. If you have a pump, you may want to tie a weight to it so it doesn't move around too much.

As the barley straw begins to decompose, it releases chemicals which stop algae from growing. It does not kill the existing algae, or any other plants. In fact, in some cases, aquatic plant growth has increased after barley straw applications because algae are no longer present to compete with the aquatic plants.

How much Barley Straw?

We recommend about 10 to 25 grams of straw per square meter of pond area. 

When should I apply the Barley Straw to my pond?

You can add barley straw to your pond all year round, but the most important factor is the temperature, in the summer months when the temperature of the water is above 20°C the process is faster compared to the winter months when the water temperature is below 10°C. Once the straw starts to decompose and release its natural chemicals, you should replace it in around 8 weeks.

3 small sacks of barley straw approx 150g in each sack for a pond 6-10m²

3 large sacks of app 500g in each sack for a pond 20-50m²
