How often should I water lilies, considering the various factors that might influence their hydration needs? Are there specific conditions under which these elegant plants thrive better, perhaps related to the type of soil, the climate, or even the season? Would the frequency of watering differ between varieties, such as Calla lilies or other types, and how might their growth stages alter their demands for moisture? Should I be particularly attentive during hotter months or after a heavy rain, adjusting my watering routine accordingly? What role do the size of the pots play, and should I consider the drainage capabilities of the soil? Could the health of the plant itself offer clues, perhaps through its foliage or the vitality of its blooms? How do these factors intertwine to create an optimal environment for my cherished lilies, ensuring they remain lush and vibrant throughout their growing season?
