Q: My water garden doesn’t ice over, but the water gets cold. Can I still use barley extract during the winter?

A: Barley straw is effective stuff. It’s an all-natural, chemical-free option for keeping pond water clear. And the best part? The temperature-tolerant natural pond treatment can be used year-round—even if your pond’s water gets cold.
Ever wonder how this seemingly innocuous bale of dried barley straw works? Read on to learn more.
Though researchers have yet to precisely pinpoint how barley straw works, it’s generally believed that as a barley straw bale breaks down in water, it produces and releases many chemical compounds—and one of them may promote clearer pond water.
It has not been found to harm fish, water fowl or pond inhabitants in any way and, in fact, some studies suggest the straw benefits fish health.
When using barley straw in a water garden or backyard pond, forward-thinking hobbyists originally placed bales of it in their waterfall filter boxes, skimmers or waterfall areas where it would decompose. Things have sure changed! Those unwieldy bales have since been replaced by compressed, easy-to-use pellets and barley extract, which is basically the good stuff in a bottle.
If you’re thinking about using barley straw in your water garden, you have more options than ever. Check out these four popular methods:
- Barley Straw Bales: Typically available loose in a mesh bag, small bales of barley straw can be placed in the pond several months before pond clarity issues are expected to occur (around March or April, depending on your climate) as the straw must start to decompose before it releases it’s special compounds. In a 1,000-gallon pond, 1 pounds of barley straw is needed, but it should be replaced every four to six months. Keep the straw well-aerated, floating it near your waterfall or stream or in shallow water. Don’t leave it in your pond beyond its prime time, however, because it can eventually become a nutrient source for algae.
- Barley Pellets: Compressed into a compact form, Barley Straw Pellets also contain all the beneficial substances found in barley straw without the unsightly look of bales, pillows or pads. The pellets may also buffer pH and control alkalinity in your pond. A 6-pound bag will treat an 800-gallon pond for up to six months; a 12-pound bag will treat a 1,600-gallon pond for up to six months.
- Barley Extract: Offering the benefits of barley straw without the mess or unsightly bale floating in your pond, Barley Straw Extract contains those beneficial substances in liquid form. Because you don’t have to wait for the barley straw to decompose, it goes to work on contact. An 8-ounce container treats up to 4,000 gallons for three months; a 16-ounce bottle treats up to 8,000 gallons for three months.
- Seasonal Defense®: Seasonal Defense® gives you the power of activated barley straw with an additional punch of natural bacteria in one simple treatment. Used when water temperatures drop below 50°F, Seasonal Defense® helps break down muck caused by leaves, scum and sediment.
No matter what form you choose, barley straw extract is a good tool to keep in your water garden tool chest. It’s an effective solution you’ll use all year round.
