Walking onions, also known as “topsetting” onions, are a unique and rewarding vegetable to grow. These perennial plants produce bulbs both at the top of the stalk and at the base of the plant, making them a continual source of delicious, flavorful onions. But knowing how to harvest walking onions is essential to ensure a healthy and productive crop year after year. This guide will walk you through the process of harvesting walking onions, from identifying ripe bulbs to storing them for future use.
Understanding Walking Onion Growth Habits
Before we delve into the specifics of harvesting, let’s understand how walking onions grow. They have a unique growth pattern, producing two types of bulbs:
- Topset Bulbs: These bulbs form at the top of the flowering stalk, resembling a cluster of miniature onions. They are typically harvested when they are about the size of a quarter or larger.
- Base Bulbs: These bulbs are the main root system of the plant, similar to traditional onions. They are harvested in the fall after the plant has gone dormant.
When to Harvest Walking Onions: A Guide to Timing
Timing is crucial when harvesting walking onions to ensure you get the most flavorful and usable bulbs.
Topset Bulbs:
- Harvesting Time: Topset bulbs are ready for harvest when they are firm and about the size of a quarter.
- Harvesting Method: Simply snap off the topset bulb cluster from the stalk. You can often harvest multiple topset clusters from a single stalk throughout the growing season.
Base Bulbs:
- Harvesting Time: Harvest base bulbs in the fall after the plant has gone dormant and the leaves have died back. This typically occurs in late fall or early winter.
- Harvesting Method: Dig up the entire plant, carefully remove the base bulb, and store it for later use.
Harvesting Topset Bulbs: A Step-by-Step Guide
1. Identify Ripe Bulbs: Look for topset bulbs that are firm and about the size of a quarter. They may be green or slightly brown, depending on the variety.
2. Snap Off the Bulbs: Gently snap the topset bulb cluster off the stalk. You may need to use your fingers or a small knife to separate the bulbs.
3. Harvest Throughout the Season: Continue harvesting topset bulbs as they mature throughout the growing season.
Harvesting Base Bulbs: A Comprehensive Guide
1. Prepare for Harvest: In late fall or early winter, after the plant has gone dormant, prepare to harvest the base bulbs.
2. Dig Up the Plant: Use a garden fork or shovel to gently dig up the entire plant. Be careful not to damage the base bulb.
3. Remove the Base Bulb: Carefully remove the base bulb from the plant. You can store it for later use or replant it to start a new colony.
Storing Your Walking Onion Harvest
Proper storage is essential to preserve the freshness and flavor of your walking onion harvest.
Topset Bulbs:
