Step-by-Step Guide to Growing Sunflower Microgreens

1. Gather Your Supplies

Before starting, make sure you have all the necessary materials:

• Sunflower Seeds: Choose seeds specifically labeled for microgreen production.
• Growing Tray: Shallow trays (at least 1-2 inches deep) work well. Ensure they have drainage holes.
• Growing Medium: High-quality potting soil or coconut coir mixed with compost is ideal.
• Water Spray Bottle: For gentle watering.
• Cover: A dark lid or another tray to block light initially.
• Light Source: Natural sunlight or grow lights.

2. Prepare Your Growing Medium

1. Fill the Tray: Begin by filling your growing tray with about 1 inch of your chosen growing medium.
2. Moisten the Medium: Water the medium until it’s evenly moist but not soggy.
3. Level the Surface: Smooth the surface to ensure even seed distribution.

3. Sow the Seeds

1. Seed Density: Scatter sunflower seeds generously across the surface of the growing medium. Aim for about 2-3 tablespoons per tray, depending on the size.
2. Press Down: Lightly press down on the seeds to ensure good contact with the soil, then cover them with an additional thin layer of soil (about ¼ inch).

4. Water and Cover

1. Water Sparingly: Use your spray bottle to moisten the top layer lightly. Do not saturate the soil at this stage.
2. Cover the Tray: Place another tray on top to create darkness and retain humidity, which aids germination.

5. Germination Phase

1. Light and Warmth: Place the covered tray in a warm, light-seeking area (around 70°F to 75°F or 21°C to 24°C) for 4-5 days.
2. Check Regularly: Remove the cover every day to check moisture levels. Spray the surface if it feels dry.

6. Light Exposure

Once most seeds have germinated and sprouted (about 4-5 days), remove the cover and expose the trays to light. If using grow lights, keep them on for 12-16 hours per day.

7. Caring for the Microgreens

1. Watering: Continue to mist the microgreens daily. Ensure that they’re always moist but never drowned.
2. Air Circulation: Good air circulation prevents mold. You can gently fan the microgreens if needed.

8. Harvesting

1. Timing: Sunflower microgreens are typically ready for harvest in 7-14 days once they reach about 4-6 inches tall and develop their first true leaves.
2. Harvesting Technique: Use clean, sharp scissors to cut the microgreens just above the soil line.
3. Immediate Use: Rinse them lightly and use them fresh. They can last in the refrigerator for about 5-7 days.

Troubleshooting Common Issues

• Mold Growth: This may occur due to excess moisture. Ensure you’re not overwatering and provide good airflow.

• Leggy Growth: This usually happens from insufficient light. Increase light exposure time or intensity.

• Poor Germination: Check the age of your seeds, as older seeds may have reduced germination rates.
