Planting too early in the season can decrease germination rate, and increase germinating seed and seedling mortality. Plants that have been planted in soil that is too cold exhibit symptoms similar to those planted in soil that has poor nutrient value.

More accurate way of planting tender crops like annuals and vegetables than using last frost date alone. This is because planting by the calendar disregards weather variations from year to year. Timing planing based on soil temperature helps assure plants get a good start.

The Soil Thermometer is manufactured by Luster Leaf Products Inc. and provides both Fahrenheit and Celsius readings.
