Last year, I was careless with the garlic I grew, leaving it lying around in the garden for a long time, then hanging up in the eaves of the pergola. Consequently, some of the bulbs were eaten by maggoty things and became unsightly. I think one reason for my carelessness was that I couldn't imagine needing so much garlic anyway.
However, as it turns out, the amount I made last year was just enough to see us through a whole year, and now as the last lot is coming to an end, the new lot is ready. This year I produced a bit more than last year, and I intend to be more careful with it, so there may be enough to bottle in miso as a tasty, breath-enhancing complement to fried rice and other dishes.
If you eat garlic and fancy trying your hand at producing veg, garlic is a good thing to start with. Just plant bulbs a few inches apart around October, mulch the ground very heavily, and forget about them until May. That's it.
