What To Know
- Loosen the soil to a depth of 12-18 inches to create a conducive environment for root growth.
- Place the seedlings in the prepared holes and fill the holes with soil, gently firming it around the base of the plants.
- Spring onions are ready to harvest when the white bulbs are about 1 inch in diameter and the green tops are about 6-8 inches tall.
Spring onions, also known as scallions, are a versatile and flavorful addition to any garden. Transplanting spring onions is a crucial step in their growth cycle, ensuring healthy and productive plants. This comprehensive guide will provide you with step-by-step instructions, tips, and troubleshooting advice to help you successfully transplant spring onions.
Selecting Healthy Spring Onion Seedlings
The foundation of successful transplantation lies in choosing healthy seedlings. Look for seedlings that are:
- Vigorous: Seedlings should be upright, with strong roots and healthy foliage.
- Disease-free: Inspect seedlings for signs of pests or diseases, such as yellowing leaves or wilting.
- Uniform size: Choose seedlings that are similar in size to ensure even growth after transplantation.
Preparing the Soil
Spring onions prefer well-drained soil that is rich in organic matter. Prepare the soil by:
- Amending: Incorporate compost or manure to improve soil structure and fertility.
- Tilling: Loosen the soil to a depth of 12-18 inches to create a conducive environment for root growth.
- pH: Spring onions thrive in slightly acidic soil with a pH between 6.0 and 6.8.
Choosing the Right Location
Select a location that receives plenty of sunlight, as spring onions require at least 6 hours of direct sunlight per day. Avoid areas with heavy shade or waterlogged soil.
Transplanting the Seedlings
1. Dig Holes: Dig holes wide enough to accommodate the root ball of the seedlings and deep enough to allow the white bulb to be covered with soil.
2. Space the Seedlings: Space the seedlings 2-3 inches apart to allow for proper growth and airflow.
3. Remove Seedlings from Trays: Gently remove the seedlings from their trays, taking care not to damage the roots.
4. Planting: Place the seedlings in the prepared holes and fill the holes with soil, gently firming it around the base of the plants.
5. Water: Water the transplanted seedlings thoroughly to settle the soil and provide moisture.
Watering and Fertilizing
- Watering: Water spring onions regularly, especially during hot and dry weather. Avoid overwatering, as it can lead to root rot.
- Fertilizing: Fertilize spring onions every 2-3 weeks with a balanced fertilizer.
Pest and Disease Control
Spring onions are generally resistant to pests and diseases, but they can be susceptible to:
- Onion maggots: Treat with insecticide if necessary.
- Downy mildew: Use fungicides to prevent or control this fungal disease.
Harvesting Spring Onions
Spring onions are ready to harvest when the white bulbs are about 1 inch in diameter and the green tops are about 6-8 inches tall. To harvest, gently pull the onions from the soil.
Troubleshooting
- Leggy seedlings: Provide more sunlight or transplant the seedlings deeper into the soil.
- Yellowing leaves: This can indicate overwatering, nutrient deficiency, or disease. Adjust watering frequency or fertilize the plants.
- Bolting: Spring onions may bolt (produce flowers) during hot weather. Harvest the onions immediately to prevent them from becoming woody.
