Measure the soil temperature a few inches down. Below 5 Celsius and
you are wasting your time. Above 10 Celsius, and you should have
planted earlier, but they will grow faster and so you have lost little.

Thanks Nick That is tucked away in my notes. Is that true for all
plants? How about my tubs?

No, but it is true for many of the frost sensitive plants that we
grow. Only ones adapted to the far north start growing when the soil
is cold. The same rule applies to tubs.
