How to Plant & Grow Garlic in Oregon


Garlic has been grown in the home garden for use as a food and medicine and for religious purposes for thousands of years. Most commercially grown garlic is a soft-neck variety, but home gardeners experimenting with hard-neck varieties will discover many variations of flavor. Some of these varieties produce a topset that appears to be a miniature garlic head. These topsets can be eaten for a more subtle garlic flavor. Italian Silver Skin and Rocambole garlic are hard-neck varieties that do well in Oregon. Commercially grown Silver, California Early and California Late also thrive in Oregon gardens.

Step 1

Plant garlic in the fall. October is the best planting month in most parts of Oregon. Separate the cloves into individual bulbs one or two days before planting.

Step 2

Prepare a location with well-drained soil. Dig or till the soil with a trowel to loosen it. Most locations in Oregon have acidic soil and need lime added to adjust the pH to 6.5 to 7.0. Mix in 1 to 2 lbs. of 10-10-10 fertilizer per 100 feet of row.

Step 3

Plant the bulbs 2 inches deep, pointed end up, approximately 4 to 6 inches apart. Cover the row with a 3- to 4-inch layer of organic mulch. Pull or hoe weeds as soon as they appear.

Step 4

Water the bulbs regularly beginning in the spring. Stop watering two weeks before harvest. Give approximately 1/2 inch of water twice a week.

Step 5

Fertilize again three to four weeks after the plants sprout. Apply 1 lb. of 10-10-10 fertilizer about 4 inches to the side of a 100-foot row.

Step 6

Check the bulbs for maturity beginning in late June in Oregon. Harvest cloves when the head contains fully developed cloves covered in a dry, papery skin. Cloves left in the ground too long will split and be hard to harvest.

Step 7

Harvest bulbs by digging them up, slicing the roots below each bulb with the trowel or a sharp knife. Garlic roots grow deep, making it difficult to pull up the bulbs.

Step 8

Dry the bulbs in a warm, dry area. Remove the roots and trim the tops or braid the bulbs.
