That must be it - the clay soil. Soil here is almost all sand. But back in Corpus if I remember right it was clay there too.You're in the wrong part of east TX then! Come over to my house. Last year and this year, we put up GALLONS of them. We just call them black berries though. Some are smaller, but we have some that get as big or larger thn grapes. They grow best in the clay soils between the pines and/or around oil locations. We use them for smoothies. My husband's football boys love those smoothies so much that many times throughout the summer we had a a dozen boys out here helping us pick berries. Fun times.![]()
