The little gem seed package I have says sow three seeds every 6" but, I do them in rows very close together and thin out to get the 6". The first thinnings go to the chickens then I make salad out of them.
Ah a good restaurant, something I miss cause out here in the boonies there is no such thing. Heck we don't even have a good BBQ joint here which sinful being in Texas. Pretty you have to cook yourself here if you want good food.
The same goes for grocery stores, produce dept. really is pitiful. I have to drive at least a 1/2 hour to the nearest decent grocery store. Austin & San Antonio have great stores, too far for me to drive. Even in Boerne or Kerrville the stores lack much in the way of organic produce.
Daughter that lives here will shop in San Antonio sometimes and says Little Gem lettuce goes for 4-5 bucks a head. When she told me that I thought good thing I grow my own now.
