Product Information

Barley Straw is the perfect way of controlling blanketweed. Not only is it effective, it's also completely natural. Our bales are the perfect size for a variety of ponds.

Algae can be a real problem left unchecked. Blanket weed can quickly spread over your pond and stop vital light and oxygen from getting through. It can block drainage, ruin the look of the pond and cause unpleasant odours to permeate the garden.

Barley Straw is a cheap and environmentally friendly way to combat algae. As it breaks down, algae busting chemicals are released into the water. Microbes consume the nutrients that algae thrive on too, so it stops any further outbreaks.
