Planting Guide for Evergreen Hardy Onions

Materials Needed:

• Evergreen hardy onion seeds
• Seed trays or small pots
• Seed starting mix
• Plastic wrap or humidity dome
• Grow lights or a sunny windowsill
• Watering can or spray bottle
• Plant labels

Step-by-Step Planting Guide:

1. Prepare Containers:
   • Fill seed trays or small pots with a high-quality, well-draining seed starting mix. This will provide the best environment for seed germination.
2. Sow the Seeds:
   • Sow evergreen hardy onion seeds about 1/4 inch deep in the soil. Space the seeds 1 inch apart in seed trays or sow a few seeds per small pot. Label your containers with the planting date and variety.
3. Watering:
   • Gently water the soil using a spray bottle or a watering can with a fine nozzle. Keep the soil consistently moist but not waterlogged.
4. Create a Humid Environment:
   • Cover the seed trays or pots with plastic wrap or a humidity dome to retain moisture and warmth. This helps speed up germination.
5. Light and Temperature:
   • Place the covered containers in a warm location with temperatures around 65-75°F (18-24°C). Evergreen hardy onions need plenty of light to grow well. Place them under grow lights or in a sunny windowsill where they can receive at least 6-8 hours of light daily.
6. Germination:
   • Evergreen hardy onion seeds typically germinate within 7-14 days. Once seedlings appear, remove the plastic cover or humidity dome.
7. Thinning:
   • When the seedlings are about 2 inches tall, thin them to ensure proper spacing. Leave the strongest seedlings and space them about 2 inches apart in the tray or pot.
8. Continued Care:
   • Continue to provide ample light, water regularly, and maintain a temperature of around 65-70°F (18-21°C). Rotate pots if using a windowsill to ensure even light exposure.

Soil Tips for Growing Evergreen Hardy Onions Indoors

1. Soil Texture:
   • Use a well-draining seed starting mix to prevent waterlogging, which can lead to root rot. Avoid heavy or compacted soils.
2. Nutrient Management:
   • Evergreen hardy onions benefit from balanced soil nutrition. Use a high-quality seed starting mix that includes a slow-release fertilizer or supplement with a diluted liquid fertilizer every 4-6 weeks.
3. Moisture Management:
   • Keep the soil consistently moist, but not soggy. Overwatering can cause root rot and other fungal issues. Use a watering can with a fine spout to control the amount of water.
4. Container Size:
   • As the onions grow, consider transplanting them into larger pots or containers to allow more space for root development. Choose containers with good drainage holes to prevent water accumulation.
5. pH Level:
   • Evergreen hardy onions prefer slightly acidic to neutral soil (pH 6.0-7.0). Use a soil pH test kit to check your soil and adjust if necessary. Adding compost or organic matter can help maintain the right pH balance.

Harvesting Evergreen Hardy Onions

1. Timing:
   • Begin harvesting evergreen hardy onions when they reach about 6-8 inches in height. Regular harvesting encourages continuous growth.
2. Harvesting Method:
   • Use clean scissors or garden shears to cut the green tops about 1 inch above the soil line. This method allows the onions to continue growing and producing more greens.
3. Continuous Harvest:
   • Evergreen hardy onions can be harvested multiple times. As long as the growing conditions are maintained, you can enjoy a fresh supply of onion greens throughout the year.

By following these planting and soil tips, you’ll enjoy a steady supply of fresh, flavorful evergreen hardy onions grown indoors. Happy gardening!
