Love to. Garlic is the easiest lazy crop there is. When it sends up the seed scapes in the early summer, don't remove them. They will "flower" and produce a crop of bulbils, which are small bulbs at the top of the scape. Leave these in place until they get quite large. They will get up to 1/2" in diameter. You can then pick them off and plant them where you want your next crop of garlic. (or you can just let them fall to the ground and plant themselves.) I warn you: it will take a while. They will send up a tiny bit of growth the first year, looks like a couple of blades of grass. The following spring, you'll have a single clove from each bulbil. Leave that in place, and the following year, you'll have a typical head of garlic there. Now, depending on how much garlic you use, how much garden space you have, and whether you till or not, you can leave a clump of garlic in place indefinitely. I have clumps of garlic that are about 8 - 10" in diameter at the roots. They consist of MANY heads clumped together. When the leaves die down in mid summer, I harvest enough heads to carry me through the year, and leave the rest of those clumps right where they are. Until this season, garlic was every where in my garden, all stages from recently sown bulbils to 10" clumps. This year, I re-organized my garden, so dug up most of those clumps, and put them in a single row. They are spaced about 1' apart, and the row is about 30' long. I broke up some clumps and took them to a fund raiser plant sale. I sold every pot I took, and could have sold a lot more. Am thinking that garlic plants would be a great spring cash crop. People really became interested when I explained how garlic can be a perennial crop.
For northern gardeners, you want to be sure to grow a stiff necked variety. I am zone 4, and don't do anything to protect my garlic over the winter. But, my soil is sandy loam. Did you know that bulbs have the ability to draw themselves deeper into the soil? They actually use their roots to pull themselves down if they are not planted deep enough. Ever noticed that when you plant tulips or hyacinths, and dig them up several years later, they're deeper than you remember planting them? How awesome is that. Who taught them how to do that????
