A Gardening Tool: Seed Germination Temperature Chart
Soil temp chartSoil Temperature plays a major role in whether seeds sprout quickly, slowly, or not at all. Every type of seed has an ideal soil temperature range for germination, and planting too early in cold soil can lead to poor germination rates or rotting seeds. In this guide, we’ll share a helpful seed germination temperature chart so you can determine the best planting time for vegetables, herbs, and flowers. You’ll also learn how to measure soil temperature accurately and use it as a simple gardening tool to improve seed starting success.
Have you ever wondered exactly when you can plant your seeds outside? With varying weather every year, picking a set date can be hard, but an easy way to ensure successful germination is knowing the soil temperature that your seeds prefer!
Grab a soil thermometer and our seed germination temperature chart to see if your soil is ready for planting!

How to Measure Soil Temperature
Soil temperature plays an important part in successful seed germination. Nutrient and water uptake cannot take place without the proper soil temperature. Each type of seed has different requirements when it comes to this, so it's a good idea to know a little bit about what the seeds you're planting might need!
The good news is that measuring your soil temperature is super easy! Once you get your soil temperature probe (which you can easily find online or at a local garden center), you'll just need to stick it into the soil in the area that you are planning to plant in. The end should be about 3 to 4 inches deep - an analog thermometer should give you a reading pretty quickly and a digital thermometer may take a few seconds before providing a reading.
- Place the soil thermometer 3 to 4 inches into the soil. For a digital thermometer, turn it on first and then place it in the soil.
- Allow time for the thermometer to register the soil temperature. It should just take a second or a minute.
Beyond Temperature: Optimizing Soil pH and Texture

Sue – Thank you for pointing this out to us. We love hearing from our customers and appreciate your feedback. We’ve included a black-and-white version of the temperature chart that will use much less ink. We hope this helps.
Do you realize how much ink it takes to print a page like your white on green germination Temperature chart??? Looks nice, but, OH, my!
