Last frost date - how to find out?
I am waiting for the "last frost date" to do a lot of things in my garden as a lot of the plants I have in pots come with instructions on waiting until the last frost date to do anything with them and my covered patio is getting very crowded now with newly purchased plants in nursery pots.
But, a quick google search on my city name and frost date comes up with different dates. So, who officially determines when the last day of frost is? TIA for your help.
