Expert Guidance on Planting Candy Onions

Dr. Emily Carter (Horticulturist, The Vegetable Garden Journal). “To successfully plant candy onions, it is crucial to select the right variety suited for your climate. Begin by preparing the soil with organic matter, ensuring it is well-drained and rich in nutrients. Plant the onion sets about one inch deep and six inches apart to allow for optimal growth.”

John Mitchell (Agricultural Extension Agent, Local State University). “Timing is essential when planting candy onions. Ideally, you should plant them in early spring as soon as the soil can be worked. This allows the onions to establish themselves before the heat of summer, which can cause them to bolt.”

Linda Thompson (Organic Farming Specialist, Green Earth Cooperative). “When planting candy onions, consider using a mulch layer to retain moisture and suppress weeds. This practice not only promotes healthy growth but also enhances the sweetness of the onions by providing a stable growing environment.”
