Planting and Germination

Seed Preparation

Before planting microgreens, seeds must be properly prepared. Start by gathering the necessary tools and materials, such as microgreen seeds, small cups or containers for soaking, and a small colander. Soak the seeds in water for a few hours so that they can easily absorb moisture and germinate. After soaking, drain the seeds using the colander.

Sowing Seeds

To sow the seeds, prepare a growth tray filled with 1 to 2 inches of a suitable growing medium like a seed-starting mix or a combination of potting soil and peat moss. Lightly compress the soil and moisten it until it feels damp but not soggy. Evenly spread the seeds across the soil line, ensuring that they have enough space for growth. It’s essential to maintain a consistent seed density, especially if growing in bulk, as overcrowding can lead to stunted growth and disease.

Watering and Heat

Watering microgreens is crucial for their growth. The best approach is to water from the bottom by pouring water into the tray and allowing absorption into the growing medium. Always ensure that the soil remains damp but not overly saturated. During the germination stage, provide a consistent heat source, such as a heating pad, to maintain optimal temperatures for seedlings to sprout.

Germination Process

Once the seeds are sown, cover the tray with a lid or another tray to create a humid environment suitable for germination. Place the tray under grow lights or a sunny windowsill to ensure the seedlings receive adequate light during their growth. Depending on the variety of microgreens being cultivated, the germination process could take anywhere from 4 to 14 days.

During this stage, it is essential to monitor the water and temperature levels and provide ample light for the seedlings. When the seeds germinate and sprout, remove the lid and the heat source. As the seedlings grow, continue to water from the bottom and adjust lighting as needed to prevent leggy growth or crowding. Soon, your microgreens will mature and be ready for harvest.

Caring for Microgreens

Optimal Temperature and Sunlight

Microgreens thrive in temperatures between 65 and 75 degrees Fahrenheit. To ensure optimal growth, place the growing containers near a sunny windowsill or provide supplemental lighting. Be cautious of placing the microgreens too close to the window, as high heat or cold drafts can negatively affect their growth.

Watering Techniques

Proper watering is essential for microgreen growth. Use bottom-watering techniques by pouring water into the tray and allowing the soilless mix to absorb it. This method helps prevent mold and diseases while keeping the plants properly hydrated. Water the microgreens consistently, ensuring that the growing medium remains damp but not soaked. Overwatering can lead to rot and inhibit growth.

Fertilization

Although most microgreens do not require fertilization, some varieties, such as sunflower microgreens, may benefit from the addition of a diluted liquid fertilizer. When using fertilizer, choose a product with a balanced ratio of nitrogen, phosphorus, and potassium, as well as added iron. Apply the fertilizer to the growing medium after the seeds have germinated and true leaves start to appear.

Recognizing Potential Issues

Monitor your microgreens closely, paying attention to any potential issues:

  • Seed Density: Overcrowding can lead to poor air circulation and increased risk of disease. Ensure that seeds are sown with enough space to allow for proper growth.
  • Mold or Fungus: If mold or fungus appears on the surface of the growing medium, it may be a sign of overwatering and poor ventilation. Reduce watering and increase air circulation to combat this issue.
  • Pest Issues: Although microgreens are relatively pest-free, occasionally aphids or other small insects may infest the plants. Inspect regularly and remove pests promptly with a gentle spray of water or by using an organic insecticide.

By keeping a close eye on temperature, sunlight, water, and potential problems, your microgreens can flourish and be ready for harvest in as little as 14 days.

Harvesting and Storing Microgreens

When to Harvest

Microgreens are typically ready for harvest when they have reached an ideal height of 1-3 inches and have developed their first true leaves. This usually occurs within 7-14 days after planting, depending on the seed type and growing conditions.

Ideal Harvesting Techniques

To ensure that you preserve the flavor, nutrition, and overall quality of your microgreens, follow these harvesting techniques:

  • Use clean, sharp scissors or a knife to snip the microgreens just above the soil level.
  • Harvest right before you plan to use them in order to maintain the highest level of nutrients and freshness.
  • Gently wash the microgreens in fresh water to remove any dirt or debris.

Some popular microgreens varieties to consider growing include red cabbage, spinach, and lettuce.

Storing Microgreens

Proper storage of microgreens is crucial for retaining their flavor, nutrients, and short shelf life. Keep these tips in mind for storing your harvested microgreens:

  • Gently pat the washed microgreens dry with a clean towel or paper towel.
  • Wrap them in paper towels to help absorb any excess moisture.
  • Place the wrapped microgreens in an airtight container or resealable plastic bag.
