As a Calla Lily, my existence is a testament to the power of the rhizome. This thick, fleshy stem that lies at the base of my being is not just my anchor and my storehouse of energy; it is the very means by which my lineage continues. When a gardener decides to divide me, they are not harming me but rather assisting in a natural process of renewal and multiplication. From my perspective, this is a vital conversation between us. Here is how I would guide you through the process, step by step, to ensure my offspring thrive.
I will tell you when I am ready. You will notice that my clump has become exceptionally dense. The leaves might seem more crowded than in previous seasons, and the number of my magnificent flowers may have decreased in size or quantity. This is because my rhizomes have multiplied underground, competing for space and nutrients within the confines of the pot or garden bed. I am essentially root-bound. The ideal time for this procedure is after I have finished my main flowering cycle and my leaves have begun to yellow, typically in late summer or early autumn. At this point, I am entering a period of dormancy. My energy has retreated from my foliage and is concentrated in my rhizomes, making this the perfect moment for division with minimal stress to my system.
Please be gentle. Start by carefully watering the soil around me to loosen it. Then, using a garden fork or spade, insert the tool a good distance away from my central clump to avoid slicing through my precious rhizomes. Work your way around me, gently levering me upward until I am free from the earth. Shake off the excess soil and rinse the remaining dirt from my root mass with a gentle spray of water. This will allow you to see the structure of my rhizomes clearly, which is crucial for the next step.
Now, observe my architecture. You will see a network of thick, horizontal stems—these are my rhizomes. Look for natural points of division where smaller rhizomes, each with at least one growing point or "eye" (a small, bud-like protrusion), branch off from the main parent rhizome. Using your hands, you can often gently twist these sections apart. If the connection is too strong, use a sharp, sterile knife to make a clean cut. Sterilizing the blade with rubbing alcohol is essential to prevent introducing pathogens into my fresh wounds. Ensure that each new division has a healthy section of rhizome with one or more eyes and a good portion of roots attached. These are the self-contained units that will grow into new, independent plants.
After the division, it is wise to allow the cut surfaces on my rhizomes to dry and form a protective callus. Place my new divisions in a cool, dry, and shaded location for a day or two. This simple step significantly reduces the risk of rot when I am replanted. It is a moment of rest for me, a chance to seal my wounds before embarking on a new growth cycle.
Finally, it is time to settle my divisions into their new homes. Plant each rhizome about 3-4 inches deep, with the eyes facing upward, in well-draining soil. Whether in a pot or a new garden spot, ensure I have room to grow. Water me in thoroughly after planting to settle the soil around my roots. This initial hydration is vital for signaling that it is time to begin growing again. As the seasons turn, I will draw upon the energy stored in my rhizome to push forth new roots and leaves, eventually producing a new generation of stunning flowers, continuing the cycle of life you have helped facilitate.
