garlic chive is almost care-free, once it started growth. and under most climates it won't die during the winter, just take a break. cut and grow again, just like lawn grass.
the only tricky issue is difficulty on starting from seeds, because they have short expiration time, seeds stored after more than 1 year are as good as nothing.
the best way is getting some roots from friends who already grow a lot.
