Watering your onions with the correct amount is crucial to your onions' development and success. In this edition of "The Onion Patch", we break down how to make sure your onions are receiving just the right amount of water with the "checkbook" method. 

Happy Onion Growing,

Checkbook Method to Watering Onions
Onions are highly sensitive to underwatering and overwatering. Research has shown that a single episode of moderate water stress any time from the four-leaf stage to the eight-leaf stage can result in reduced bulb single-centeredness. With these facts in mind, it is tempting to err on the side of overwatering - however, overwatering can rot the crop, either in the field or on the shelf.

Think of watering your onions like a checkbook. The soil is the bank account and water is either added or taken away. Rain and irrigation are deposits while water used by the crop and water evaporated from the soil through evapotranspiration are withdrawals. The goal is to estimate the amount of water in the crop root zone and prevent the crop from experiencing water stress. Water depletion varies with the soil texture. Silt and clay are fine-textured soils and hold more water than coarse-textured soils such as sand. Sandy soils require more frequent irrigation. The amount of evapotranspiration (ET) is variable depending on the amount of solar radiation, wind, air temperature and humidity. ET data is often available from weather stations in specific production regions. Once you know how much you are losing to ET, you can resupply this loss with either irrigation or rainfall. 

For most areas in the country, the daily forecasted ET range in the 0.35-0.45 range during the summer months (July-August) During the spring (May-June) the ET range will be much smaller in the 0.1-0.3 range. In the winter, the ET range can be extremely low in the 0.01-0.1 range. That is what needs to be replaced by watering. Here's a link to Daily FRET (Forecast Reference EvapoTranspiration). 
Daily FRET

Onions should be watered immediately after planting. During the first month after planting, water demand is fairly low. Onions are developing new roots and most these initial roots are shallow compared to other crops. Most of the roots are within the top 10" of soil. Light, frequent irrigations should be applied.

During the second month of planting the root system of the onion begins to expand in to the top 20" of the soil. As the onion grows, foliage becomes denser and leaf area increases, which leads to more transpiration and increased irrigation needs.

During the bulbing stage, water demand gradually increases to fill the rings with water and complete the bulbing process. In addition, this usually equates to warmer weather when the ET will be at its highest. Frequent, heavy irrigations will be required until the bulbs reach the marketable size and the tops start to fall over. At that time, irrigation should cease to allow the crop to dry in the field and increase shelf life.

From Our Friends
When temperatures drop below freezing, customers with onions in the ground call and ask us how to protect their onions. We recommend adding mulch or hay around them and to be sure to water them in well. 

Robin and her 10 year old son, John, of Bedford, TX shared their method of keeping their onions warm during the super cold temperatures with us. They place PVC pipe over rebar and cover their raised bed with plastic. The temperature was 19°F outside and windy, but in the upper 40°Fs in this hoop house. Here is a photo of their Texas Legend and Leeks.


This is an easy method for our customers that have raised beds and may save your onions from an unexpected late spring freeze!

Thank you for sharing your method with us, Robin and John! We wish you a great 2019 growing season.
