Additionally, how might the prevailing climate conditions, like humidity and temperature fluctuations, impact the water requirements? Furthermore, what role does the type of soil play in retaining moisture or draining excess water? Are there signs I should meticulously observe, such as yellowing leaves or drooping branches, that could signal either overwatering or underwatering? In juggling these various considerations, how can I arrive at a definitive guideline that caters to my lemon tree’s unique environment and needs?
