The optimal timing for relocating established Rheum rhabarbarum plants centers around periods of dormancy. This typically translates to either early spring, before new growth emerges, or late fall, after foliage has died back completely. Selecting these times minimizes stress on the plant, allowing it to establish itself in its new location before facing the demands of active growth or harsh weather conditions.
Careful timing contributes significantly to the plant’s survival and future productivity. By transplanting during dormancy, the plant can focus its energy on root development in the new site, rather than supporting existing foliage. This approach increases the likelihood of a successful transition and continued yields in subsequent seasons. Historically, gardeners have observed greater success rates when adhering to this dormant-season practice.
