Every year I plant these, on a small mound with the roots splayed out ,as directed by the garden shop. But the shoots emerge for about 3 inches
from the soil, and they then just wither and disappear. It is not slug damage.
Your Eremurus need to be in full, direct sunlight in a spacious area in well-drained soil. When you have purchased them, do the rhizomes still appear fleshy and not dried out?
