Plant Care & Growing Tips

Successful cultivation of Corinthian yellow onion sets requires attention to a few key environmental factors and regular care. Onions thrive in well-prepared soil and require consistent moisture and sunlight to develop large, healthy bulbs. Begin by selecting a site that receives at least 6-8 hours of direct sunlight daily. Good air circulation is also beneficial to prevent fungal issues. Prepare your soil by amending it with compost or well-rotted manure to improve fertility and drainage. Onions prefer a slightly acidic to neutral pH, typically between 6.0 and 7.0.

When planting your fresh seed onions, ensure the soil is loose and friable. Plant the onion sets about 1 inch deep and 4-6 inches apart in rows that are 12-18 inches apart. The top of the onion set should be barely covered with soil. Water thoroughly after planting. Consistent moisture is crucial, especially during the bulbing stage. Aim for about 1 inch of water per week, either from rainfall or irrigation. Avoid overwatering, which can lead to rot, but do not let the soil dry out completely. Fertilize every few weeks with a balanced fertilizer, or one higher in nitrogen early in the season, switching to a more phosphorus and potassium-rich fertilizer as bulbs begin to form.

Weeding is essential as onions do not compete well with weeds for nutrients and water. Hand-weed carefully to avoid disturbing the shallow root system of the onion plants. As the bulbs begin to swell, some gardeners gently pull back the soil from around the top of the bulb to encourage larger growth, though this is optional. Harvest your Corinthian yellow onion sets when the tops begin to yellow and fall over, typically in mid to late summer. Cure the onions in a warm, dry, well-ventilated area for several weeks before storing them in a cool, dark place for long-term enjoyment.
