How often should I water a cactus plant, considering the myriad factors that could influence its hydration needs? Is there a one-size-fits-all answer, or does the frequency vary depending on the specific species of cactus and its environmental conditions? For example, how do factors such as the size of the pot, soil composition, and even the season play into the equation? When it comes to this hardy succulence, could overwatering be just as detrimental as underwatering? As someone who appreciates the beauty and resilience of cacti, isn’t it crucial to ascertain the ideal balance in moisture levels to support their growth? Additionally, what role does local humidity and temperature serve in determining the watering schedule? Should I be observing the plant’s physical cues, such as the firmness of the pads or the color of the soil, to gauge its water requirements more accurately?
