Does anyone know if it would be ok to cut all the leaves of the helebores now, as they are taking a big space in the garden?
Now is not the right time.
By all means cut of dead leaves and old flowering stems... but not the new leaves.
The time to take of the leaves that are there now, is spring 2014 before the flowers open.
Hope this helps.
Ok thank you SS, I will leave them then.
