Planting Onions: Step-by-Step Guide

– Onions can be planted either from seeds or sets (small bulbs). The planting time depends on your climate and the type of onions you’re growing.
– For spring onions, plant sets or seedlings in early spring.
– For overwintering onions (to be harvested the following year), plant sets in autumn.

3. How to Plant Onions from Bulbs

– Choose a sunny location with well-drained soil.
– Prepare the soil by adding compost or organic matter to improve fertility.
– Dig shallow trenches about 1 inch deep and 4-6 inches apart.
– Place onion bulbs (sets) in the trenches with the pointed end facing up.
– Cover the bulbs with soil and lightly firm the soil around them.
– Water thoroughly after planting.

4. How to Plant Onions from Seed

– Start onion seeds indoors 6-8 weeks before the last expected frost date.
– Plant seeds in seed trays filled with seed-starting mix.
– Keep the soil consistently moist and provide adequate light.
– Transplant seedlings outdoors when they are 4-6 inches tall and the soil is workable.
– Plant seedlings in well-prepared soil, spacing them 4-6 inches apart in rows.
– Water regularly to keep the soil evenly moist.

5. How to Plant Onions that Have Sprouted

– If you have onions that have sprouted in your kitchen, you can plant them to grow new onions.
– Cut off the sprouted part, leaving about 1 inch of the onion bulb intact.
– Plant the sprouted onion bulbs in well-drained soil, with the sprouted part facing upwards.
– Keep the soil moist and wait for new green shoots to emerge.

6. Caring for Onions

– Onions require regular watering, especially during dry spells.
– Keep the area around onions free from weeds, which can compete for nutrients.
– Fertilize onions sparingly with a balanced fertilizer once or twice during the growing season.
– Mulch around onion plants to conserve moisture and suppress weeds.
– Monitor for pests and diseases, such as onion thrips and fungal diseases, and take appropriate measures if necessary.

Harvesting Onions

– Onions are ready for harvest when the tops start to yellow and fall over.
– Gently lift onions from the soil using a garden fork.
– Cure harvested onions by drying them in a warm, well-ventilated area for 1-2 weeks.
– Once cured, trim the tops and store the onions in a cool, dry place.

Tips for Success

– Plant onions in raised beds or containers if you have limited garden space.
– Rotate onion crops every year to prevent disease buildup in the soil.
– Consider companion planting with carrots, lettuce, or herbs to maximize space and deter pests.
