Hello, I am taking a botany course and had some trouble with some of my seeds. The class was given the task of planting different seeds that we would later examine, and I had peas. The instructors note was to plant your seeds in the soil about two times their diameter down As I had large peas, I planted the seeds about a centimeter or so below the surface. All of my classmates who used peas did the same thing. Their seeds germinated, mine did not. I cannot figure out why this happened. We used the same soil, same light, and the same amount of water for each of the pea plants. Would there be any other factor that would single out my plants? Any information would be appreciated.
