Step 1: Selecting the Right Variety of Spring Onions

Before you start growing spring onions, it’s essential to choose the right variety that suits the Singapore climate. Some common varieties that thrive in Singapore include “Evergreen,” “White Lisbon,” and “Red Beard.” Consider factors such as taste preferences, growth habits, and disease resistance when selecting the variety that best suits your needs.

Step 2: Choosing the Ideal Location for Growing Spring Onions

To ensure the successful growth of spring onions, selecting an ideal location is crucial. These vegetables require a sunny spot with at least six hours of direct sunlight daily. Prepare the soil by removing weeds, breaking up clumps, and enriching it with organic matter such as compost.

Step 3: Planting Spring Onions

There are two main methods for planting spring onions: starting from seeds or transplanting seedlings. If you choose to start from seeds, sow them directly into the prepared soil, ensuring a spacing of about 1 inch between each seed. Alternatively, you can start seeds indoors in seed trays and transplant the seedlings when they are around 4 to 6 inches tall.

Step 4: Caring for Spring Onions

Proper care is essential to ensure healthy growth and abundant harvest of spring onions. Water the plants regularly, keeping the soil consistently moist but not waterlogged. Fertilize the plants with a balanced organic fertilizer every four to six weeks to provide them with essential nutrients. Monitor the plants for any signs of pests or diseases and take appropriate measures to control them.

Step 5: Harvesting Spring Onions

Spring onions are typically ready for harvest when their leaves are around 6 to 8 inches long and have a rich green color. To harvest them, gently pull the plants out of the soil, taking care not to damage the roots. Alternatively, you can snip off the green leaves with a sharp pair of scissors, leaving the white bulb in the ground for regrowth.
