Vegetable Seed Germinating Temperatures
Below are guidelines to minimum temperatures required for reasonable germination. In general, seeds should be sown at the beginning of the season, when outdoor temperatures are likely to rise rather than fall. However, you are advised to read the notes on the seed packet for your particular country.
N.B. Most vegetable and herb seeds will germinate well/more quickly at higher temperatures.
