How often should I water peppers? Is there a specific frequency that optimizes growth and ensures that the plants flourish without becoming waterlogged or drought-stressed? Considering factors such as the variety of pepper, climate conditions, and soil type, could you delineate a comprehensive watering schedule? Moreover, might it be pertinent to explore the distinctions in moisture requirements during different growth stages, such as germination versus fruiting? In addition to standard irrigation practices, what role does mulch play in moisture retention? Could you elucidate on the signs of both overwatering and underwatering that would indicate a need for adjustment? Furthermore, how might seasonal variations influence watering needs and what should be taken into account when transitioning from one season to another? Ultimately, how can one achieve the delicate balance of keeping the soil sufficiently moist while avoiding detrimental water accumulation? Would this nuanced understanding not lead to a more fruitful pepper harvest?
