Confirming my previous observation I found that in three and a half year old seedling bed growing under the same conditions the size of bulbs varied from 1 to 4 inch diameter.
In your opinion why is it so?
Is it genetic or the weaklings could not compete with others in extracting nourishment from soil?
I think they are genetically weak or just small. I am planning to pull them out and create another bed for further observation.
