We used to hold back the best for the next crop's plating, but I always disliked putting my best back into the ground rather than eating them.
Around a decade ago now, I decided to explore other options. If you have the room and a little patience, you might want to consider this method.
The scapes eventually ripen into a bulbil packing sphere. I leave around a half dozen to do this each year now. These are this years still in the ground to finish ripening:
Eventually they will look like this and are close to harvest time:
I cure these in mesh bags, then hang for the winter in our cold room.
In the spring the individual bulbils get separated and planted into planters' boxes. They grow quickly over the summer:
These produce singular small clones - most will not be sectioned cloves, rather singular and about the size of a marble.

It is a Hybrid developed specifically for the Island.
Based on a blend of Russian Red Hardneck and a similar variety produced by Gabriola John (famous garlic producer).

Including much of BC and some in Saskatchewan and Alberta.
