Why do gardeners check soil temperature?

Video · 1:45 · Crafty Clover explains, from A Million Whys Book 29

Seeds sprout best when soil is warm enough, and each plant has its own limit. Peas sprout in cool soil, but beans and corn want it much warmer. A soil thermometer pushed in a few inches shows when it's time. Planting too early in cold soil can make seeds rot. Waiting a week or two for warmth usually gives better results.

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do gardeners check soil temperature?

The Big Idea

Gardeners take the soil's temperature! Just like a doctor checks yours. Why?

Each Plant's Limit

Step one: Each Plant's Limit. Seeds sprout best when soil is warm enough, and each plant has its own limit. Peas sprout in cool soil, but beans and corn want it much warmer.

Measuring

Step two: Measuring. A soil thermometer pushed in a few inches shows when it's time to plant. Soil warms more slowly than air in spring.

Patience

Step three: Patience. Planting too early in cold soil can make seeds rot. Waiting a week or two for warmth usually gives better results.

A Closer Look

Let's take a closer look! Cool is fine. Want warmth. Want warmth. Shows when.

Quick Facts

Quick facts! Soil warms more slowly than air in spring. Peas like cool soil. Corn wants warmth. Cold soil can rot seeds.

Think Like a Scientist

Now, think like a scientist! Push a soil thermometer a few inches into the soil. Check it each morning for a week. Write down each reading. Make a graph. Is the soil warming up?

Outro

Seeds sprout best when soil is warm enough, and each plant has its own limit, so peas like cool soil while beans and corn want warmth. A soil thermometer shows when it's time, because seeds planted in cold soil can rot. Science is amazing! Remember, every big discovery starts with a small question. Keep looking, keep learning, and keep asking why! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
