Garlic starts life as one small clove taken from a mature bulb. When planted in the right conditions it slowly turns into a full new bulb made of several cloves. The whole process usually takes seven to nine months.
Planting the clove and early root growth
Gardeners break a healthy bulb into separate cloves and plant each one with the pointed tip facing up. The flat base sits about five to eight centimetres deep in loose, well-drained soil. Roots begin to grow from the base within days or weeks. This early root system anchors the plant and takes in water and nutrients while the clove uses its stored energy.
In cooler climates the clove is usually planted in autumn so the roots can establish before winter. A period of cold weather helps the plant prepare for proper bulb formation later.
Green shoots and leaf growth above ground
As the soil warms in late winter or early spring the first green shoots push through the surface. The plant then focuses on growing long, flat leaves. Each new leaf helps build the future protective layers around the bulb. Strong, healthy leaves mean the plant is collecting energy from sunlight that will later feed the developing bulb underground.
During this stage the plant needs steady moisture and light. Weeds should be kept clear so the young garlic can grow without competition.
The switch to bulb formation underground
When days grow longer in late spring the plant changes direction. Energy that was going into new leaves now moves down into the base of the stem. The single planted clove begins to swell and divide into several new cloves. This happens out of sight beneath the soil. From above the plant still looks like a cluster of green leaves, but the real work is happening below.
Hardneck types may also send up a curly flower stalk called a scape at this time. Softneck types usually stay focused on the bulb.
Filling out the bulb and signs of maturity
Over the next weeks the new cloves grow larger and firmer. The outer leaves start to turn yellow and dry from the bottom upward. This is the signal that the bulb is nearly ready. When about half the leaves have yellowed while the top ones are still green, the garlic is mature.
Pulling the bulbs too early gives small or soft cloves. Leaving them too long can cause the skins to split and reduce storage life.
Harvesting and the final step of curing
The mature plants are carefully lifted from the soil so the bulbs stay intact. They are then laid out or hung in a warm, dry, airy place for two to four weeks. This curing process dries the outer skins and necks, sealing the bulbs so they keep well for months.
Once cured the bulbs can be cleaned, sorted and stored. The largest, healthiest ones are often kept to plant again the following season, continuing the cycle from one tiny clove to the next full bulb.
Growing garlic rewards patience. From a single clove buried in cool soil to a complete bulb ready for the kitchen, the process follows a clear and reliable path driven by temperature, day length and steady care.
