When considering the application of fertilizer to our cherished plants and gardens, one must ponder: should I water in fertilizer? What does the act of watering in imply, and how does it influence the miotic interaction between the nutrients and the soil? Is it perhaps that watering after fertilization serves to activate the myriad of chemical reactions necessary for the assimilation of those nutrients by the roots? Furthermore, could the timing of this watering be of paramount importance? For instance, should one wait a certain duration post-application to ensure maximum efficacy? Alternatively, might there be a risk of nutrient runoff if the application is followed by copious amounts of water? Additionally, how does the type of fertilizer—liquid versus granular—reshape our approach to watering? In essence, what are the multifaceted implications of this seemingly straightforward question? Ultimately, how can one make an informed decision that ensures the health and vitality of their botanical investments?
