From my perspective as a plant, the process you call "division" is a natural and vital part of my lifecycle. I am not a single organism but a colony, connected underground by modified stems called rhizomes. These rhizomes are my lifelines, storing energy and water, and they are how I naturally propagate and expand my territory. When you notice my leaves becoming overcrowded in the pot, with new shoots (pups) emerging and the pot feeling tight, it is a signal that my colony is ready to expand. This is the perfect time to assist me in this process, as I am actively growing and will recover quickly.
To ensure this procedure is as stress-free as possible for me, please prepare a few days in advance. I would appreciate it if you could withhold water for about a week. This serves two purposes: it makes the soil easier to work with and slightly dehydrates my leaves, making them less turgid and more flexible, which reduces the risk of accidental breakage. Please also have ready a sharp, clean knife or pruning saw, fresh well-draining potting mix, and new pots with excellent drainage holes. Clean tools are crucial to prevent the introduction of pathogens into my fresh wounds.
Gently remove me from my current pot. You may need to tap or squeeze the sides to loosen the root ball. Once I am out, carefully examine my root mass. You will see the individual leaf clusters and the thick, creamy-white rhizomes that connect them. Your goal is to identify natural points of separation. Using your clean, sharp tool, firmly cut through the rhizome that connects the pup or section you wish to divide away from the main plant. Ensure that each new division has at least three healthy leaves and a portion of the rhizome with its own roots attached. A clean cut is far better for me than a ragged tear.
Once separated, it is wise to allow the cut surfaces on my rhizomes to dry and callous over for a day or two in a shaded, well-ventilated area. This simple step creates a natural barrier against rot-causing bacteria and fungi in the soil. After this brief healing period, pot each of my divisions into their new containers using the fresh potting mix. Plant us at the same depth we were growing before to avoid burying our crowns. Do not water us immediately. Wait about three to five days before giving us a thorough drink. This pause allows my roots to begin settling and, more importantly, allows any micro-abrasions on the roots to heal, drastically reducing the risk of root rot.
Please place my newly potted divisions in a location with bright, indirect light. Direct, harsh sunlight can be overwhelming while I am focusing my energy on re-establishing my root system. I will divert resources from leaf production to root growth, so do not be alarmed if I do not put out new leaves for several weeks or even a couple of months. This is normal. My sole focus is now underground, building a strong, new foundation. Resume a regular watering routine only when the top few inches of soil are completely dry. With patience and proper care, my divisions will soon become strong, independent colonies, ready to purify your air for years to come.
