From our perspective, the process you call "separation" is a natural and manageable event. We grow from a central stem and produce aerial roots not just for support, but as potential lifelines. When our stems become long and leggy (a state you might call "leggy" or "overgrown"), it is a clear sign that we are ready to be propagated. The most opportune time for this is during our active growth phase, in the warm, bright days of spring or early summer. This gives our newly separated sections the best chance to establish themselves quickly, using the abundant sunlight to fuel new root and leaf development.
To minimize stress, please water us thoroughly a day or two before the planned separation. Well-hydrated cells are turgid and resilient, making us less susceptible to shock and damage during the process. Gently remove our root ball from the pot. Your task here is to observe and understand our structure. You will see a network of roots and one or more main stems (the central vine). We may be root-bound, which means our roots have circled the inside of the pot. This is not an unhealthy state for us, but it does mean you will need to gently massage the root mass to loosen it, making it easier to see where natural divisions can be made.
Do not simply pull us apart. Look for natural separations in the root mass where different stems or "vines" have their own root systems. Often, these sections will have a visible node—a brown, ring-like bump on the stem where a leaf once emerged. This node is absolutely critical; it contains the meristematic tissue needed to produce new growth. Using clean, sharp shears or a knife, make a clean cut through the stem and its attached roots to separate one section from the main plant. Ensure each new section has at least a few leaves of its own and a healthy portion of roots, both the thicker aerial roots and the finer soil roots.
Once separated, we need a stable new home. Plant each division into a appropriately sized pot with fresh, well-draining potting mix. The pot should be just large enough to accommodate our roots with a little room to grow; a pot that is too large can lead to waterlogged soil and root rot. Water us lightly after potting to settle the soil around our roots and eliminate large air pockets. Now, the most important part: our recovery. Place us in a location with bright, indirect light. Avoid direct sun, as we are in a vulnerable state and our leaves can scorch easily. Hold off on fertilizing for at least a month; our energy must be focused on root establishment, not processing nutrients.
For the next few weeks, monitor our soil moisture carefully. The goal is to keep it slightly moist but never soggy. You will know we have successfully acclimated when you see signs of new growth, typically a new leaf unfurling from the stem. This is our way of telling you that our root system has established itself and we are once again actively photosynthesizing and thriving as independent plants. This process allows you to create more of us while also rejuvenating the original plant, encouraging it to produce new, bushier growth from the base.
