When the outer five leaves are brown, its ready.I guess I need to check my garlic... How do you tell if it's ready?
I planted a ton last fall and had 55 come up - yikes! I planted a mix of hardneck and softneck varieties. Hardneck produce a scape which is the seed head, but you need to cut the scape, in order to force the plant to put its energy into developing the bulb rather than the flower. When it puts up the scape, it will go up and then curl around. Wait until it has done a full loop and then the scape is ready to be harvested. Cut it with pruners and you can use the scape itself in cooking. It will have a very mild garlic flavor. After you cut the scape, wait a little longer while it develops the bulb and then when the outer 5 leaves are brown, you can dig up the bulb.
I had always heard that hardneck varieties mature later than softneck, but the first two bulbs that were ready to be dug this year were hardnecks. Since then I've dug a mix of hard and soft necks - about 10 in all. Only 45 to go....
