Break up garlic sprouts?

So it seems I lost track of some garlic and forgot to harvest it. I found a bunch of sprouts today all near each other. Should I dig them up and space them out?

Yes. I've lost track of loads too and have been doing that for two years now. Almost self sustainable in garlic now.
I plant them in small rows or patches when the volunteers pop up, so i'll miss less next year. I kind of will know where to look for them. But still a fourth or something i do miss, they wilt early or late or unnoticed. But that is just great in fact.
Very easy quick replanting. If you use a long thin trowel you can plant most of the longer roots deeply without disturbing other volunteers.
Putting them at different places in your garden makes full use of their deterring capabilities for bad insect and bad fungi, if i remember well.
Can plant some in shady spots that will lead to fresh garlic at a later time.
Nothing but advantages being a bit sloppy, finally!
I've had some of them flower as well and then they leave a lot of tiny bulbils in the top. Planted those and they came up, planted them out, but it's a fiddly job that. Timewise splitting bulbils and replanting is so much quicker that i'll just eat those small bulbils next time.
Happy planting!

What Hugo said, but it depends whether you've got plenty elsewhere for harvesting ripe next summer - I pull the forgotten bunches and use them green.
