Hot water seed treatment is a task that often falls on the list of "should do's" in the winter and early spring, but sometimes falls by the wayside. Treating seeds in a hot water bath can help prevent serious bacterial, fungal, and viral diseases by killing pathogens harbored within the seed. The practice is recommended for both seed collected on the farm and purchased from commercial sources. However, it's sometimes difficult to know which seeds to invest in treating, and whether it's worth the time or cost. In the past, hot water seed treatment at home meant investing in rather costly laboratory hot water baths or taking a chance on less reliable stovetop methods. With the popularity and availability of "sous vide" machines, hot water seed treatment is easier, and more predictable than ever.
