Furrow irrigation is sometimes referred to as flood irrigation. This is where we get the term “flood the beds”. Many customers ask us which is the preferred method of irrigating onions, and we usually recommend this method. Read on to learn more about furrow irrigating your onion beds. 

When to Furrow Irrigate

You will want to water occasionally but thoroughly, applying about one inch of water each time. We recommend using the “knuckle rule” to tell when it’s time to water. Stick your finger into the ground near the plants; if you can’t feel moisture up to your first knuckle, it’s time to water. In a typical 12 week growing season, we recommend irrigating with one inch of water once or twice a week depending on the amount of rainfall received. 

How to Furrow Irrigate

The furrow irrigation method encompasses “flooding the beds” in the furrows and allowing the plants to soak up water slowly and thoroughly. As a general rule, when the top of the bed is totally darkened by moisture, you have provided enough water to your onions. Furrow irrigation is the main method of watering used on our farm.
