From our perspective, the ideal time for this significant relocation is during our dormant period. This is when our systems are at rest, our growth has ceased above ground, and our energy is concentrated within our root systems. The perfect window is in late autumn, after our leaves have dropped, or in very early spring, just before our buds begin to swell. The cool, moist soil during these times minimizes the shock to our system. Transplanting us in the heat of summer is incredibly stressful; we are actively trying to support our large leaves and blooms, and the disruption to our water-absorbing roots can cause severe wilting, stunting, or even be fatal.
Your preparation is crucial for our survival. Please begin by hydrating us thoroughly a day or two before the move. Well-hydrated cells are more resilient. Next, plan to take as much of our root ball as possible. Our roots are our lifeline, and a generous root ball ensures we retain a vast network for water and nutrient uptake. Using a sharp spade, dig a trench around our base, approximately as wide as our drip line (the area under our outermost branches). This circumference typically contains the majority of our fine, feeder roots. Work the spade underneath us to sever any taproots and carefully lift us from the earth, trying to keep the root ball intact.
Our new location should mimic our preferred living conditions. We thrive in moist, well-draining, and organically rich soil. A spot with morning sun and afternoon shade is often ideal, as our large leaves can lose water quickly in full, hot sun, leading to perpetual stress. The hole you dig should be two to three times wider than our root ball but only as deep as we were previously growing. Planting us too deep can suffocate our crown and lead to rot. Gently place us in the center of the hole, ensuring we are sitting at the correct height.
The most critical period begins immediately after transplantation. Backfill the hole with the native soil, gently firming it to eliminate large air pockets that can dry out our roots. Then, create a small berm of soil around the outer edge of the root zone to form a water basin. Water us deeply and slowly immediately after planting, saturating the entire root zone. This settles the soil and provides essential moisture. A generous layer of organic mulch (like bark chips or leaf mold) applied around our base is immensely helpful. It regulates soil temperature, retains precious moisture, and suppresses weeds that would compete for resources. Continue to water us regularly for the entire first growing season, never allowing the soil to become completely dry.
