Garlic needs about 1 inch of water per week during the spring growing season. Keep weeds under control early. Garlic does not compete well with weeds. Harvest after leaf die back begins and there are still five green leaves remaining on the plant sometime in June. Varieties mature at different rates due to genetic make up and weather conditions.
Harvest time is a judgment call.
Do not wait too long or the bulbs will begin to separate in the ground. Dig the garlic carefully, do not pull the stalk or it will separate from the bulb. Gently brush most of the dirt off do not wash. Be careful, do not toss or bang the garlic against a hard object or each other. It will bruise.
