Four years ago we dedicated a raised bed to growing asparagus. Did lots of research, purchased plants, planted them and followed all the rules for weeding, watering and feeding. Sadly, they have not performed and we have decided to get rid of them. A friend has expressed an interest in taking on these plants, so before chucking them on the compost heap we wondered if anyone has ever transplanted the plants/roots? If so, when would be the best time of year to do so?
