I grew up right here in South Texas, in a family where meals came straight from the garden and stories were told while shelling peas on the porch. My earliest memories are of pulling weeds beside my grandfather, helping my mother jar pickles from cucumbers we grew ourselves, and learning, season by season, how to listen to the land.

Here at BrownsvilleFarmersMarket.com, I share what I’ve learned over the years not just how to grow crops, but how to nurture soil, nourish health, and rebuild food wisdom from the ground up.
