How many seeds should I plant per hole, and what considerations should I take into account to arrive at an optimal figure? Is there a universally accepted number that applies irrespective of the seed type or the environmental conditions? When contemplating this question, one must consider variables such as the specific crop being cultivated, the intended density of the plants, and the overall health of the soil. Additionally, how does the size of the seeds influence the number that can be planted without causing competition among seedlings? Could factors such as moisture retention, sunlight exposure, and soil nutrients also play critical roles in determining the ideal quantity? Furthermore, what about the potential consequences of overcrowding versus underplanting? How can gardeners and agriculturalists strike a balance that maximizes yield while ensuring the vitality of each individual plant? In short, what empirical guidelines exist to navigate this intricate dilemma?
