If I might share a rookie mistake with ya'll.... I had read about companion planting, and thought, wow what a great way to maximize our limited space this year! Well I didn't do enough research. I planted my carrots under the tomato and bell pepper plants. Now I don't know if they didnt get enough sun, or if the bigger plants are taking all the nutrients, but, I have 3-5ft tops, on 3in carrots! I don't remember my gramma's carrots ever having tops that tall. And she had nice long, plump carrots every year.
