The amount of veggies I eat is minimal.
I've been eating my YG taters nearly every day since I dug the first batch and the total 12lbs will last me, I'm guessing another two months.
Sure, I could have bought that much at Wallyworld, or the Amish market up the road for a few $$ instead of digging, watering, weeding, and waiting three months. But I don't use chemical fertilize or pesticide on mine... and no one has touched them but me.
I garden because I enjoy the process.
Now, tomatoes on the other hand, I don't have much luck with and this will probably be my last year trying.
I can buy one nice big fat Purple Cherokee from the Amish that will last me a week.
I'm having great luck with potatoes though.
