Hi NB,
This has been done many times over the years but somehow the strain seem to have lost its vigour. Time to start afresh.
I make a fair amount of potato salad every year and from about 20 clumps I sometimes struggle to find enough chives to cut.
Hi Glallotments,
The seed has come from a garden where the chives have never been cut and the person never grows anything for himself. I suppose nature could sow by the moon

but I would rather put it down to total neglect.
JB.
