I have heard in the past that one shouldn't plant tomatos in ground until
night time temperatures are 50 and above. I've heard that under 50 temps
stunt the growth of the tomatos the rest of the season. Yet I see nurseries
and places like Home Depot that have their plants outside when temperatures
are still in the 50's or 60's during the day, and well below 50 at night and
they don't seem to have problems. I've always held off until the end of May
here in Syracuse (region 5) to plant my tomatos but as long as it's not near
freezing at night, should it matter?
