How often should I water fruit trees, especially when considering the myriad of variables that can impact their hydration needs? Is it merely contingent upon the species of tree, or could factors such as the age of the tree, soil type, and climatic conditions play a pivotal role? For instance, during the sweltering months of summer, is there a standard frequency that experts recommend to ensure optimal growth and fruit production? Moreover, do the watering requirements differ between young saplings and well-established trees? Can overwatering be just as detrimental as underwatering, leading to issues such as root rot? Additionally, how does one ascertain the moisture level in the soil before deciding to water? Could advanced techniques like soil moisture sensors provide the necessary data, or is a more traditional method of checking the soil’s texture still sufficient? Ultimately, what are the best practices to adopt for maintaining the health and vitality of fruit trees throughout the seasons?
