A Gardening Tool: Seed Germination Temperature Chart

Soil temp chart

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 you can ensure successful germination is knowing the soil temperature that your seeds prefer! We've put together a handy guide to help you grow.

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.

Here's what you'll need:
