Planting Garlic

This is a description of how we plant our garlic. We understand that our way isn’t the only way to do it, but it has worked for us for over two decades. Every year we improve on it a little. We share our experiences for beginners and veterans alike, hoping you’ll gain something from our story. These photos were taken from July 2009 to April 2010, and show the progression of our garlic planting during a typical year.

Harvest, August 2009
A few weeks after the end of harvesting the scapes, all of the stalks have straightened up and the bulbils have begun to fatten. We now watch the garlic patch closely for the sign of the lower leaves beginning to turn yellow. Since each leaf is a wrapper around the bulb, as the leaves turn yellow, that wrapper layer begins to disintegrate. When there are only five or six green leaves left, the harvest begins.

The Garlic Harvest begins with pulling the garlic stalks and bunching them as we go. After pulling and bunching a row, a loop of bailing twine is used to bundle about twenty stalks at a time. The bundles are then hung in a shed to dry for up to a month before all the bulbs are cut off for cleaning. A few are immediately cut and cleaned for market, but cleaning is much easier after the bulbs have thoroughly dried.

Once the bulbs are removed, the bulbil clusters are left to dry further, and eventually cut or snapped off. The empty stalks are then used to mulch perennials, and the loops of bailing twine are stored away until next year’s harvest.

The first bed of garlic, five rows to a bed, is pulled and laid in bunches, ready to wrap twine around for hanging. The garlic from each bed is removed prior to pulling the next bed to avoid getting too crowded in the field.
Bundles are loaded onto the trailer, using care not to get the garlic tops from different bundles entwined with one another.

Even though we try to plant all of our garlic cloves and rounds with the root end down, we always manage to find a few that were planted upside down. It doesn’t seem to bother the garlic all that much—the garlic adjusts quite well. But it does seem to be asking it to a little more than if it were planted correctly. If you ever see some of your garlic looking like this, that is what happened.

In the fall of 2009, we planted 7,000 row feet of garlic for harvest in August, 2010: seven 250 ft. long beds with four rows per bed. Plant spacing and row spacing were six inches, meaning we planted 14,000 cloves and rounds. This is a significant expansion for us from previous years.

Planting, October 2009
Our technique for mulching garlic consists of mulching the planted beds with shredded leaves or pine needles, then going back and mulching the aisles with whole leaves. In the photo at right you can see the beds in the process of being mulched, and bags of whole leaves in one of the aisles ready to mulch that aisle.

Shredded leaves or pine needles don’t mat down during the winter, so the garlic shoots can emerge right through the mulch come spring. Whole leaves, on the other hand, do tend to mat down, giving any weeds in the aisles a very hard time. You can see in the top photo how few weeds have emerged by early August harvest time. This thick mulch also cuts down on the need to water and adds a huge amount of organic matter to the soil every year.

Right after the garlic is harvested, broccoli seedlings are transplanted through the old mulch, giving us a late October broccoli harvest.

After the garlic beds are mulched with shredded leaves, bags of whole leaves are laid out in the aisles for emptying.

The first step in planting the garlic bulbils is to break up the clusters and winnow out the papery husks. Fortunately this is a breezy time of year, and winnowing can be done outdoors.

The bulbils are planted two rows to a bed. First a furrow is made with a rake, and bulbils liberally sprinkled into the furrow. Then the rake is used to slightly cover the bulbils, and finally a layer of mulch is added. Note the holes in the bed to the left where garlic rounds have been planted.

Once the garden rake makes a furrow and the bulbils sprinkled in, the same rake is used to cover the bulbil row. Two rows to a bed are done this way

Once the furrow has bulbils sprinkled in it, the rake is used to fill the furrow back in, burying the bulbils.

Below are photos from the following April, where the bulbils planted in the above photos are now emerging thru pine needles (left) and thru shredded leaves (right).

About 1/3 of the garlic was planted with rounds, and about 2/3 with cloves. About half a bed was dedicated to softneck garlic for a two week earlier harvest.
We also have two beds of garlic planted in Greenhouse 1 which will allow us to harvest scapes in June and garlic bulbs in July.
