How important is soil temperature when it comes to planting my seeds in the spring?

Answer 1

Not that important, even if the soil is warm, you should be watering it annually so it will cool it down. But an even more important element of the soil you have is the PH levels, this can make some plants thrive and others suffer in the same soil. You will also have to consider this when choosing the right type of fertilizer.

Answer 2

This is probably the most important factor in planting, and the main reason for germination failure in spring planting. While cool weather crops such as chard, lettuce, peas etc. can germinate when the soil temperature is only 40 degrees F, warm weather plants such as beans, squash, melons, cucumbers, etc. need a soil temperature near 70 degrees to germinate properly. Even tomato and pepper plants (which need to be started inside) benefit from an artificial heat source for the soil to achieve proper seed germination. Another factor to consider is the various beneficial microorganisms in the soil. Most do not become active until the soil temperature has reached 45 degrees F., and do not reach the height of their activity until the soil temperature reaches into the 70's. Remember, just because you experience a few warm days in the spring does not mean that it's time to plant all the vegetable varieties in your garden. Check the soil temperature first!

Answer 3

It is important. But so is the acidity and moisture of the soil.
