Garlic seed called bulbils produce only one large clove the first year of growth. Planting the clove again three cloves are produced. Planing the third year perfect clones of the parent are produced. Planting successively year after years makes more of the main crop available for use. Another advantage is the bulbils are completely disease free. Garlic is asexual so no new garlic is ever produced only clones of the original.Garlic in my area is planted in October and harvested the following year in early July. It is amongst the easiest vegetables to grow.

Seeds collected, washed in water and allowed to dry.

Very interesting

I tend to "lose" garlic in my garden, and round about this time of year i find the lost garlic sprouting in little clumps of 6 or so

Is it safe/ok to split them now?

it will be fine to dig them up and split them off into individual plants, they will grow away fine
