Hi, we have been growing garlic now for 5 years on a pretty small scale, about 1 acre. Have been to field days, read literature & spent too many hours looking on the net. This has to be one of the most frustrating things I have ever been involved with. Some say it is swamp plant & you can't over water, others say to let them dry out a few times as it encourages growth. Heaps of fertilizer, very little fertilizer, sandy soil is best, loam is best etc. etc. Like an earlier post let the bulb tell you, ha ha. But it is true. For our purple garlic plant in March April with mild fertilizer, we use blood & bone. We water as you would any other plant, use a moisture meter or stick you fingers in the soil to see how dry/wet it is. Occasionally top dress with b&b. Pull one out every few weeks & see what it says. One thing that is common to all advice is to not water for the last 3-4 weeks (noted when the leaves start to turn yellow & die off) as this will produce a very slimy skin not easy to work with & hard to stop rot. Again pull one up & have a look at what it's doing, it will let you know same as a citrus, potato or anything else. Just takes time to get to know it. Hope this adds to the confusion, I know I still am.
