About half my young dierama plants (grown from seed) died right back over
the winter, and there is still no sign of them. I dug one up, and there
does seem to be a small but healthy corm there - but it's doing nothing!

The ones that stayed green over the winter are putting out new leaves and
look very healthy.

Are the died back corms likely to recover, or should I chuck the ones in
pots and overplant the places where the ones in the ground were ?

There seems to be no relation between position/planting/compost and plants
that vanished over the winter.
