Ahhh garlic! my latest passion
It is getting close to the time to harvest garlic here in zone 7...like in the next 7 days. Harvest is done when the plant is 60% green and 40% brown/yellow and when the scape is completely unfurlled (hardnecks). And you harvest by putting a pitchfork in the ground and wiggleing (sp?) it back and forth. Once the dirt has loosened around the bulb, put the fork tines under the bulb and push the bulbs out of the ground. Don't pull the garlic plant out of the dirt like an onion, you will risk breaking off some of the cloves to be lost in the dirt or snapping the neck and affecting the bulbs storage life.
There are basically 2 kinds of garlic: softneck and hardneck. Hardnecks send up a scape (flower stalk) that can be eaten. I don't know about eating the other leaves of the garlic plant...they are looking a little chewy right about now
Softneck garlic generally does not send up a scape...they will scape if there has been a drought and for preservation reasons are striving to survive for the next season by making seed.
Attila the Honey, if you leave the bulbs/cloves in the ground, you run the risk of them being over-watered in the summer-time and rotting away to nothing (this happens to tulips too) or being underwatered and shrivelling away to nothing or being eaten by pest worms (again, tulips too). But they can also be left in the ground and come up fine in the fall. For the rest of the summer though, they will die back (like tulips). Were you given plants or cloves to plant? Do tulips thrive in your area/zone (come back year after year?). If tulips do well, then leave them be, you might loose a few...This is the time of year that they go dorment...so do not be surprised when they turn brown and "die." This is a tough call...I would be tempted to dig them back out and cure them. Its only been since Saturday. Assuming that you were given plants, what is the ratio of green to brown leaves?
The planting and harvesting of garlic is a regional/zonal one. Garlic growers in zones farther south than me have already harvested their crop. But the growers further north of me still have a few weeks to go until harvest time. Same applies to planting...autumn happens at different times for each zone. The time that you plant your grass seed is also the time you plant your garlic (tulips too).
