I would like to establish a biggish area of wild garlic, what would be
the best thing to do, use plants or bulbs

Do you mean, plant while they're growing or plant while they're dormant?

I've never tried planting them, though I have tried moving a few plants.
My observations are a) they grow very deep, from memory more than 6
inches down b) they're keen self-seeders, so you wouldn't need to plant
them very densely.
