Q.Will Seeds Germinate If Only A Few Hours Each Day Are Below Their Minimum Germination Temperature?

Zone 64086 | dlschmitt0911 added on April 25, 2021 | Answered

This is my first year gardening, and I’m eager to start some of my warm season crops like zucchini, watermelon, and pumpkins. I’ve researched that many say 60 degrees is the minimum temperature needed for these plants to germinate. My 14 day forecast shows that I should have temperature highs between 70 and 80 most days and lows averaging around 55. If the soil temperature goes above 60 for a good portion of the day, is it safe for me to plant these crops, or do I need to wait for soil temperatures to never drop below 60? I’ve heard cool temperatures can stunt some plants, but is that true for even small seedlings?

Yes, it will be fine to plant them. These short periods of less than ideal conditions will not be so much that it will prevent germination.

Here are some articles that will offer more information on the care of these warm season crops:
