How low of a temperature can nematodes survive in the winter? How cold does the ground get in comparison to the outside air?
Nematodes work as long as the soil is not frozen and the soil is moist. Don’t worry; soil takes a long time to react to air temperatures. If most of your plants survive the winters it is a good indication that the soil does not freeze. Even if a plant is damaged from frost above the roots are often fine as the ground is warmer. Your Beneficial Nematodes are snug and warm and going to work in your soil.
