I Just Planted Seeds Today For A Vegetable Garden. It’s Supposed To Get Close To 45 Degrees. Are They Safe?

Question

I planted tomatoes,onions, carrots, green peppers, and cucumbers. It has been warm and the ground isn’t cold. Forecast is around 45 degrees.

Answer 1

Forty-five degrees F. should be fine, although, the warmer it gets, the faster your plants will grow. Warm season veggie seeds won't germinate if the soil is too cold. The soil temperature is key. Your university cooperative extension should have soil temperature readings available to the public, or you can take your own.
