From our perspective, the optimal time for this significant event is in the early autumn, after our vibrant flower spikes have faded but while the soil still retains the sun's warmth. Alternatively, a very early spring division, just as our new growth begins to peek from the crown, is acceptable. These periods align with our natural dormancy or slow-growth phases. The intense heat of summer places too much stress on our systems, demanding excessive water and energy to recover from both bloom exhaustion and root trauma simultaneously. A fall division allows our entire being to focus on re-establishing a strong root system in the cool, moist soil before winter's rest, giving us a head start for a vigorous spring display.
To begin, please water the soil around our base thoroughly a day before the procedure. This hydrates our tissues and makes the soil more manageable, reducing root shock. Using a sharp, clean spade, dig a wide circle around the central crown, taking care to preserve as much of the taproot and its lateral feeder roots as possible. Gently lift the entire clump from the ground. You will notice that our mature form consists of a central, older woody crown surrounded by younger, more vigorous offshoots. Your goal is to carefully tease these younger sections apart, each with its own portion of healthy roots and several growing points (or "eyes"). You may need to use two garden forks back-to-back to pry stubborn sections apart or a clean, sharp knife to make precise cuts, minimizing crushing damage to our root tissues.
Our success in a new location is entirely dependent on the preparation of our new home. We thrive in well-draining soil and a position that receives full sun to partial shade. Before our arrival, please amend the planting hole with compost to ensure fertility and good drainage, as our roots are highly susceptible to rot in waterlogged conditions. The hole should be wide and deep enough to accommodate our root system without bending or crowding the taproot. Create a small mound of soil in the center of the hole upon which to rest our crown; this allows our roots to drape naturally downwards, encouraging outward growth.
Place one of our divisions into the prepared hole, ensuring the crown—where our stems meet our roots—is level with the surrounding soil surface. Burying it too deep invites crown rot, while planting too high exposes our sensitive root tissue. Backfill the hole gently, firming the soil around our roots to eliminate air pockets. Water us in deeply and immediately to settle the soil and provide essential hydration. Apply a layer of mulch around our base to conserve moisture and regulate soil temperature, but ensure it is not piled against our crown. Consistent moisture is critical in the following weeks as we establish ourselves, but the soil must never become soggy. With this careful approach, we will channel our energy into rebuilding our root community and prepare for a spectacular return in the coming season.
