I want to move 1, maybe 2, established Eremurus robustus because they are too close to where I want to establish a path. I assume it is best done in late summer, when they are normally on sale. At present they are in growth but only ~6 cms tall and single shoots.
I have planted 5 crowns over the last 4 years. The first group of 3 have stayed as single shoots while the others planted later have multiplied into 5 or 6 shoots each. I have 5-6 flower stems in total each year. They are in apparently identical positions in full sun, just 3 metres apart, but behave quite differently.
