Repotting Day Kit
Updated How we research
Repotting is the one job where being unprepared costs the tree, because exposed roots dry out while you hunt for scissors. Set the bench before you lift anything: mesh cut and wired over the drain holes, anchor wire threaded through, fresh soil sieved, root shears sharpened, and damp sphagnum ready for whatever looks fragile afterwards. The page is split into six sections (Pots for the growing years; Covering the drain holes; Tying the tree in; Cutting roots cleanly; Sifting out the dust; Aftercare for weak roots), followed by every pick ranked by our score so you can compare them in one place.
