Hello, everyone, I've recently moved to the Raleigh area from Florida. I planted some marigold seeds inside in the 1st week of February and the plants are now developing flower buds. I'm just wondering when it will be safe to start hardening them outside and plant them in the ground. I am told the "official" frost-free date is 4/5, but can marigold actually take cool temps or did I really start them way too early?!!
