When to Plant Garlic in Seattle: A Guide for Pacific Northwest Gardeners
Planting garlic in Seattle requires timing it just right to ensure a bountiful harvest. The ideal planting window for garlic in the Seattle area falls between mid-October and mid-November, allowing the bulbs to establish roots before the ground freezes.
This timeframe takes advantage of the cool, moist conditions that are conducive to root development, setting the stage for robust growth come spring.
Why Fall Planting is Key in Seattle
Garlic needs a period of cold dormancy to properly develop its bulb. Seattle’s mild winters, while not as harsh as other regions, still provide enough chilling hours for garlic to thrive. Planting in the fall gives the garlic cloves ample time to establish a strong root system before winter sets in. This early root development is crucial for absorbing nutrients and moisture come spring, leading to larger, healthier bulbs at harvest time.
Types of Garlic to Grow in Seattle
Seattle gardeners have several garlic varieties to choose from. Generally, hardneck and softneck types both perform well. Hardneck varieties, such as ‘Spanish Roja’ and ‘German Extra Hardy,’ are known for their robust flavor and the production of scapes (edible flower stalks). Softneck varieties, like ‘Silverskin’ and ‘California Early,’ are better suited for braiding and tend to store longer. Experiment with different varieties to see which performs best in your specific microclimate and soil conditions.
Planting Garlic: A Step-by-Step Guide
Here’s a brief guide to planting garlic successfully:
- Choose a Sunny Location: Garlic needs at least six hours of sunlight per day.
- Prepare the Soil: Amend the soil with compost or well-rotted manure to improve drainage and fertility.
- Separate the Cloves: Carefully separate the cloves from the bulb just before planting.
- Plant the Cloves: Plant the cloves pointy-end up, about 2 inches deep and 6 inches apart.
- Water Well: Water the planting area thoroughly after planting.
- Mulch: Apply a layer of mulch, such as straw or leaves, to help retain moisture, suppress weeds, and protect the soil from temperature fluctuations.
Caring for Your Garlic Through the Winter
During the winter months, keep an eye on the soil moisture. If the soil becomes excessively dry, water lightly. The mulch layer will help to insulate the soil and prevent it from freezing and thawing repeatedly, which can damage the developing roots. As spring approaches, you may need to remove some of the mulch to allow the soil to warm up more quickly. Consider checking the Wikipedia article on garlic for more information.
Harvesting Your Garlic
Garlic is typically ready to harvest in late June or early July. The leaves will begin to turn yellow and brown, signaling that the bulbs are maturing. Dig up a test bulb to check its size and development. Once the bulbs are large and well-formed, carefully dig them up, being careful not to damage them. Cure the harvested garlic in a dry, well-ventilated place for several weeks before storing.

Summary
The best time to plant garlic in Seattle is from mid-October to mid-November. Fall planting allows the garlic to establish roots over the winter and produce larger, healthier bulbs in the summer. Choose a sunny location, prepare the soil well, and select garlic varieties suited to the Pacific Northwest climate for a successful harvest.
