I began pulling garlic today, starting with the red Russian. Russian is the smaller, more pungent variety of hard-neck garlic that I grow. It has many more cloves/bulb than the larger German garlic, though, so it is much easier to propagate starting with a few bulbs, and ending up a couple of years later with a LARGE crop. I have mention many times that when the scapes emerge from the tops, you should snap them off and use them in salads, stir-fries, etc. If you don't like the "garlic-y green onion" taste of the scapes, you still have to snap them off, and here's why. The garlic on the left spent all its extra energy developing the flowering head and seed pod, and robbed the bulb of most of its potential.
How did this scape "escape" my attention? I inadvertently planted the clove upside-down, so that the emerging shoot had to take a lot of time finding the way up to the surface. For this reason, the scape emerged after I had already snapped most of the others, and I missed it.
Really, I know better, but when you plant as much garlic as I do, you are going to screw up here and there. Hard-neck garlics are wonderful in cold climates, and they can take a lot of harsh temperature extremes, but you have to follow the rules. Plant the cloves with the base (root end) down, and snap off the scapes as soon as the bulge in the stalk emerges from the foliage, so the bulbs get all the rest of the nutrients that the vegetative fronds can supply, for best growth.
The garlic is especially good this year, with wonderful flavor, and the cloves have the crispy consistency of water-chestnuts.
