Can I dig up and separate a huge hydrangea? Kilmarnock, VA (zone 7)
Most hydrangeas have a woody main stem that doesn't divide well. (Some types may send up multiple shoots from below ground, so it may be possible to slice through the root ball and separate out one or more of the side shoots.) If it is a well-established plant, the root system will extend well beyond the spread of the branches, so the success rate of transplanting a large plant is often not very good. If you must move the plant, the best time to do so is late winter or early spring before growth begins.
