First of all, welcome to the board. Secondly, good luck in your seng hunting. I do not know the growing schedule for Georgia but, someone else will chime in who is familiar with it, I am sure. Is the family farm ground posted to keep others out?
Don't get discouraged if you don't find tons of seng. I have some growing on my place but, not great amounts. Just knowing it will grow here has been an encouragement and I have planted some each year the last three/ four years. Some of my first plantings have actually started to produce a few seeds this year. I am excited about it. But, if you do find lots, good for you and have fun. Keep us posted.
