How often should I water my pot plants, considering the myriad of factors that influence their hydration needs? Is it merely a function of the plant species, or do environmental conditions such as humidity and temperature play a substantial role? Furthermore, should I take into account the pot size and the type of soil utilized for these plants? Might the watering frequency change depending on the season, with warmer months necessitating more frequent watering than the cooler ones? Additionally, how does the presence of drainage holes in pots affect the overall moisture retention? Could it be that the specific light conditions—whether direct or indirect sunlight—also impact the rate of evaporation? Is there a nuanced difference in the hydration requirements of succulent plants compared to ferns or tropical varieties? Finally, should I rely solely on a calendar, or would it be more prudent to assess the moisture level of the soil prior to determining water needs?
