When to plant Pre-Rooted Onions

Pre-rooted onions can be planted outdoors from early spring to late summer, depending on the variety. They establish quickly in the ground, allowing for an earlier and more reliable harvest. For the best results, plant them in well-drained soil once the risk of hard frost has passed.

How to Plant Pre-Rooted Onions

Choose a sunny location with fertile, well-draining soil. Loosen the soil and mix in organic matter or well-rotted compost to improve nutrients. Space the pre-rooted onion sets 10-15cm apart in rows, ensuring the roots are well-covered with soil. Water them well after planting and maintain consistent moisture throughout their growth.

How long do Pre-Rooted Onions take to grow?

Pre-rooted onions mature faster than traditional onion sets, usually taking around 12-16 weeks to reach harvesting size. You can start harvesting young onions for salads earlier, while larger bulbs will be ready later in the season.

Why should I plant Pre-Rooted Onions?

Pre-rooted onions establish quickly and offer a head start compared to traditional onion sets or seeds. They are more resilient to pests and diseases, resulting in a higher success rate for gardeners. Growing your own onions ensures a fresh, chemical-free supply that tastes far superior to store-bought alternatives.

Where can I plant Pre-Rooted Onions?

Pre-rooted onions grow best in open garden beds, raised beds, or large containers. They require a sunny spot with at least six hours of direct sunlight daily. If space is limited, they can be grown in deep pots on patios or balconies.
