Growing Walla Walla onions has been a rewarding experience for me, with their uniquely sweet flavor making them a favorite in my kitchen. Understanding the right time and method to harvest these delicate bulbs is crucial. I typically look for the tell-tale signs that they’re ready to be pulled from the earth, which usually include the yellowing and falling over of the onion tops, signaling that they’ve finished growing. This tends to happen in late summer or early fall, after approximately 90 to 130 days of growth, depending on the conditions.
I’ve learned that the process of harvesting must be done with care to avoid damage to the onions. I gently use a fork or spade to lift them out of the soil rather than tugging on the tops, which can lead to bruising. After I lift them, I lay them out to cure in a sheltered spot that stays cool and is well-ventilated. The curing process, which takes about two weeks, toughens the outer layers and prepares the onions for storage. The cooler temperature helps to prevent spoilage, ensuring that the onions retain their flavor for as long as possible.
In my experience, it’s also important to remember not to wash the bulbs after harvesting—any excess soil is best brushed off dry. Once cured, I trim the roots and cut back the dry foliage before storing the Walla Walla onions in a cool, dry place. With the right harvesting and storage techniques, I always have a taste of summer handy in my kitchen, ready to be added to my meals.

Preparing the Soil and Planting Walla Walla Onions
Getting Walla Walla onions off to a good start begins with selecting the optimal site and prepping the soil just right. I’ll guide you through this process to ensure your onion patch is primed for planting.
Selecting the Right Location and Sunlight Conditions
Walla Walla onions need a bright, sunny location with at least 6-8 hours of direct sunlight daily. I make sure to pick a spot where they can bask in full sun throughout the growing season.
Soil Composition and Drainage
💥 Well-drained soil is a must for Walla Walla onions.
Onions don’t like to sit in waterlogged soil, so I always aim for a location that drains well. A telltale sign of poor drainage is if water tends to puddle after a rain—onions will definitely not appreciate that.
Amending Soil with Organic Matter and Nutrients
I improve my soil by working in plenty of aged compost or manure, which adds nutrients and enhances the soil structure. This organic matter not only feeds the onions but also supports good drainage.
Planting Tips for Seeds and Onion Sets
Walla Walla onions can be started from seeds or sets. I’ve found that onions sets generally make life a little easier—they’re small, dry bulbs that give you a head start on growth.
| Seeds or Sets | Planting Depth | Spacing | Soil Temperature |
|---|---|---|---|
| Seeds | 1/4 inch | 1 inch apart, in rows 12 inches apart | {” “}Around 40°F (early spring) |
| Sets | 1 to 2 inches | 4 to 6 inches apart, in rows 12 inches apart | {” “}Around 40°F (early spring) |
Whether I’m sowing seeds or planting sets, I always aim to get them in the ground in early spring, taking care to keep the soil evenly moist as the onions take root.
Caring for Walla Walla Onions During Growth
Growing Walla Walla onions in my garden requires some TLC to ensure a bountiful harvest. From proper watering and fertilization to combating pesky intruders and weather-related challenges, here’s how I keep my onion patch in top shape.
Watering and Fertilizing Needs
Walla Walla onions crave consistent moisture. I ensure they receive a deep watering weekly, which encourages robust root growth. Overwatering or inconsistent hydration can lead to poor development or disease.
Regarding nutrition, I feed my onions with a balanced fertilizer every 3-4 weeks. It’s like giving them a well-rounded diet that promotes healthy, vigorous plants capable of standing up to Mother Nature’s moods.
Managing Pests and Diseases
Aphids and onion maggots enjoy my onions as much as I do but in the worst way. To fend them off, I maintain a keen eye and respond swiftly with organic fungicides or insecticides when necessary.
Effects of Climate and Weather
💥 Battling the Elements
Walla Walla onions are suited to cooler seasons, yet they relish sunlight. I ensure they get at least 6-8 hours of direct, unfiltered sunlight. In scorching conditions, I may mulch around the plants to keep the soil temperature down and moisture locked in.
Temperature fluctuations or harsh weather can stress the onions, so I’m always on the lookout and ready to protect the plants with covers or additional mulching if a sudden chill is in the forecast. Every so often, the skies will throw a curveball, and it’s my job to keep those onions batting a thousand. 🌱
Harvesting and Storing for Optimal Quality
Harvesting your Walla Walla onions at the perfect moment guarantees you’ll get the best taste and longest shelf life. Once harvested, correct curing and storing practices ensure your onions stay in top-notch condition for your culinary enjoyment.
Determining the Right Time to Harvest
I know it’s time to harvest my Walla Walla onions when they’re mature, typically 90 to 120 days after planting, and the tops begin to fall over and yellow.
Techniques for Harvesting Walla Walla Onions
When the time comes, I use a fork to gently lift the onions from the soil, being careful not to damage the bulbs, which can affect their storage ability. Here’s the scoop—I harvest on a dry day and leave the bulbs on the ground to dry for a moment if the weather is cooperating.
Curing Onions for Longer Shelf Life
Curing is essential for storage. I lay them out in a well-ventilated, dry place, out of direct sunlight. This process can take up to two weeks. The onions are ready when the outer layers are papery and the necks are tight.
Best Practices for Storage
I’ve found that onions like to chill out in a cool, but not cold, dark place for long-term storage. I store my Walla Walla onions in mesh bags or netting to encourage air circulation, which prevents mold and helps maintain their quality. Always keep an eye for any signs of spoilage and use those first to avoid them affecting others.
