We recommend using a thermometer, especially in the spring, to keep a check on when different pest will be active and also when you can start to effectively use biological controls.

Minimum soil temperatures needed for nematode application is 5°C but some pests are not active until the temperature reached around 12°C

The temperature of the soil is also very important for plant growth. The suns rays warm the soil, and the plants use that warmth to drive the chemical reactions that keep them alive and drive the cells to multiply. In fact in spring the average soil temperature will be even more important than the average air temperature, as a trigger for growth. A good rule of thumb is that grass will not grow unless their roots are above 6 degrees.

Soil temperature also influences which soil pests are around and active - when the soil is very hot or very cold then grubs such as leatherjackets and vine weevil tend to bury themselves deep and not feed too much.

Finally soil temperature also influences the activity of the predators and parasites we use to control pests. Nematodes, for example, are inactive below 5 degrees, and most effective at 10 degrees and above.

For all these reasons a good soil thermometer is an essential part of soil monitoring. Our probe thermometer is the tool the professionals use. It has a strong probe which allows the heat from the soil to contact the thermometer bulb effectively.
