Planting Your Over Winter Spring Onions
Timing is Key
The best time to plant over winter spring onions is in the fall, about 6-8 weeks before the first expected frost. This allows the plants to establish themselves before the cold weather sets in.
Preparing the Soil
Spring onions prefer loose, well-drained soil with a pH between 6.0 and 7.0. Before planting, work in some compost or manure to improve soil fertility.
Planting Depth and Spacing
Plant spring onion seeds about 1/4 inch deep and 2-3 inches apart. If using sets (small bulbs), plant them 1-2 inches deep and 4-6 inches apart.
Overwintering Care
Mulching
Applying a layer of mulch, such as straw or shredded leaves, over the planting bed helps to insulate the soil and protect the plants from harsh weather conditions.
Watering
While winter is generally a drier time, it’s important to keep the soil consistently moist. Water the plants thoroughly when the top inch of soil feels dry.
Protection from Frost
In very cold climates, consider using row covers or other protective measures to shield the plants from extreme frost.
Harvesting Your Over Winter Spring Onions
