The weedy plant we call wild garlic or wild onions around here has round, hollow leaves. The leaves of your hardnecks will be flat. I'd use a dandelion weeder to twist out the wild things.

Right - if the foliage is round it may be garlic chives which is weedy in my garden, since I let it self sow some years ago. Native wild alliums are also round leaved for the most part. Those are not a garlic, rather entirely different species of Allium. You actually have to dig those out if they takes root; they break off and then resprout if you just try to pull them. Anything that self sows to seed on its own in your garden, is almost certainly not going to be garlic, and you should be able to separate the different growth habits when they show up.

If your "wild garlic" is really garlic then you have volunteer of some previous gardeners escapes and they may well be worth saving, but you should also have seen those standing out last summer. They very likely will come up in clumps and bulb out very small, even probably sending up flower scapes, which your first year bulbils should not do.

There really is no such thing as true wild garlic that can be confused with our cultivated varieties anyway, not in this country. There are some ferals of true garlic, but they will never seed; and so are relatively shortlived if you cultivate you garden at all carefully.

Do not trust the color of your rounds to be like the color of the bulbils, or even be the same themselves from year to year.

One more thing, it often pays to plant bulbils in sterilized soil in a large pot the first year. No question then of what you have, provided only that you are careful with the labels. Then you will also have one more year out of the cycle with no contact with soil borne disease.

Excellent points.

Here the "wild garlic" is what people call the wild things. They may not be true garlic, onion, etc. I think they are related to garlic/onion. They are everywhere in my yard (previous farm land). I always pull them when I dig my garden. But my garlic beds are new, so a lot of them are still in the soil. No run-away garlic.

As for growing garlic or bulbils in containers, so many people mention it, but I do not see many folks doing it here. There is so much temperature variations. And garlic is so sensitive to temperatures. The warm/cold can really harm the container garlic.

I see the points in planting new garlic in pots the first year, but not for bulbils. Bulbils do not carry soil borne diseases.

LOL Tell a Minnesotan about changing temperatures! Zone 6 is like tropical to us. One thing you can do quite easily is to drill out drainage holes in the bottom of a 5 gallon pail, add about 2" of pebbles and gravel in the bottom and bury the pail up to about its handles in the ground. Fill the rest of the bucket with sterile potting soil and keep it well watered, you may not even need to water it, actually, depending on what rain you get. Plant in that primarily to keep your new types segregated not so much for disease control.

I have done that sort of thing here in Minnesota with some of my perennials that are not any hardier than garlic. Temperature isn't your enemy for garlic in Zone 6. In fact zone 6 is just about the perfect overlap between northern hardnecks and southern softnecks. You have conditions suitable for success with a much wider variety of garlics than those adapted to our zone 4.

If you are not on pure clay, but instead on a sandy soil, that would provide a very good base to bury the ventilated 5 gallon pails in. Just leave some 4 or 5 inches out above the surrounding soil line and viola! you even have your raised beds.

There will be no danger of any wild alliums growing there, only the garlics you put in them. So you end up with no sorting and very little weeding as a bonus.

As you stated perfectly, your idea of container is a raised bed. And you do not move the pots.

For the folks who have a large property, they can certainly grow new varieties in a separate area of the yard, in raised bed or not.

For bulbils, I just do not see the concerns for soil borne diseases.

I left some round in pots from summer. They now grow to 8" tall now. I'll just take them out for garlic greens....
