What are Microgreens

Microgreens are tiny but mighty young plants, harvested just as their first leaves emerge.

They’re essentially the seedlings of herbs and vegetables, offering a denser nutrient profile and more intense flavors than their mature counterparts.

Microgreens grow easily and taste delightful, these little greens add a pop of color, texture, and nutrition to any dish. As a master gardener, I see microgreens as a perfect blend of culinary delight and gardening pleasure, all in a miniature package.

Make sure you get your seeds from a reputable seed company.

What’s Needed to Get Started

• Mason jars
• Microgreen seeds (such as alfalfa, broccoli, or radish)
• Cheesecloth or mesh for jar lids
• Rubber bands to secure the cheesecloth/mesh
• Water for soaking and rinsing
• A bowl or tray for initial seed soaking
• A dark, warm place so the seeds germinate
• A light source for growing (natural light or a grow light)

6 Simple Steps to Grow Microgreens Indoors on a Windowsill

Growing microgreens in a mason jar on a windowsill is probably the easiest food that you’ll grow. You don’t need seed starting mix, potting mix, or anything else that you usually need to grow food.

You just need the few items from the list above and in around ten days you’ll be enjoying some fresh greens.

Step 1. Soak the Seeds

Soaking seeds is a vital step in the process of growing microgreens, and it’s surprisingly simple. Start by selecting your preferred microgreen seeds and place them in a mason jar.

This jar doesn’t need to be large, just ensure it can comfortably hold the seeds with some extra space. Next, pour enough water into the jar to completely submerge the seeds.

This soaking process is crucial as it softens the seed coats. Let the seeds soak overnight, usually for about 8-12 hours.

This duration allows the seeds to absorb sufficient water to begin the germination process. In the morning, you’ll find the seeds slightly swollen and ready for the next step to grow microgreens at home.

Here are seven common microgreens to grow indoors:

1. Radish Microgreens
2. Broccoli Microgreens
3. Arugula Microgreens
4. Pea Shoots
5. Sunflower Microgreens
6. Red Cabbage Microgreens
7. Mustard Microgreens

Step 2. Drain and Rinse

To start growing microgreens, soak your seeds in a jar until you see the seed pods begin to pop open slightly.

This indicates they’re absorbing water and starting the germination process. Once you observe this change, it’s time to drain the water.

Cover the jar with cheesecloth or a fine mesh to keep the seeds contained while allowing the water to escape. After draining, rinse the seeds thoroughly with fresh water.

This step is essential to remove any remaining residue and to ensure the seeds are clean and ready for successful germination and growth.

Step 3. Germinate Seeds

The next step in growing microgreens is crucial for successful germination. After soaking and rinsing your seeds, you’ll want to create the right environment for them to begin sprouting.

Here’s how microgreens grow indoors:

• Invert the jar containing the soaked seeds at an angle in a bowl.
• This position helps drain any excess water.
• Ensures proper air circulation.
• Crucial so the seeds germinate.

Step 4. Daily Rinsing

Maintaining the health of your germinating microgreen seeds requires a simple but important routine: daily rinsing. Twice each day, take the time to rinse and drain the young seedlings thoroughly.

This process is crucial for keeping the seeds adequately moist, which is essential for their continued growth and development.

The regular rinsing also plays a vital role in preventing the growth of mold, a common issue in seed germination. By ensuring the seeds are neither too dry nor overly saturated, you create an optimal environment for your organic microgreens to flourish.

Step 5. Place on Windowsill

After your microgreen seeds have sprouted, it’s time to move them to a location where they can receive adequate light for continued growth.

The ideal spot is a sunny windowsill where the jar can get indirect sunlight. Direct sunlight can be too intense for the delicate sprouts, potentially causing them to dry out or burn.

Indirect sunlight, on the other hand, provides the necessary light without the harsh intensity. This gentle exposure to sunlight is essential for the microgreens to perform photosynthesis, leading to healthy, green growth.

The windowsill also offers the added benefit of a stable environment and easy access for your daily watering and care routine.

Step 6. Harvest Microgreens

Once the sprouts in your mason jar have grown a few inches tall and the jar appears full and lush, your microgreens are ready to be harvested.

This typically happens a week or two after placing them on the windowsill. Carefully remove the microgreens from the jar, snipping them at the base with scissors.

This method lets you gather the tender, nutrient-rich greens while leaving the roots intact inside the jar. These fresh microgreens are ideal for adding a fresh, flavorful boost to your dishes.

The beauty of growing in a mason jar is you don’t have to worry about any garden soil or harvesting them at the soil line.

What to Avoid

• Avoid over-soaking seeds: Soak just until seed pods start to open.
• Don’t let seeds dry out: Ensure consistent moisture but avoid waterlogging.
• Avoid direct sunlight: Place jar in indirect sunlight on windowsill.
• Prevent overcrowding: Don’t pack too many seeds in one jar.
• Avoid poor air circulation: Keep the jar inverted at an angle for airflow.
• Don’t skip rinsing: Rinse seeds twice daily to prevent mold.
• Avoid harvesting too early: Wait until sprouts are a few inches tall.
• Be gentle during harvest: Snip carefully to avoid crushing the delicate sprouts.

How to Prevent Common Issues

• Rinse seeds twice daily to maintain cleanliness and moisture.
• Keep temperatures consistent, ideally between 18-24°C (65-75°F).
• Use clean jars and tools to prevent bacterial and fungal growth.
• Be vigilant about pests and treat any infestations promptly with gentle methods.
• Harvest the microgreens when the first true leaves appear, typically within 1-3 weeks.

Managing Pests and Diseases

When it comes to managing pests and diseases in your microgreen cultivation, vigilance is essential. Regularly inspect your plants for signs of common pests like aphids or issues such as mold.

To prevent problems, maintain good hygiene practices by using clean equipment and ensuring the growing environment is free from debris and pests.

Adequate air circulation helps deter mold and other fungal issues, so be mindful of the growing conditions. Avoid overwatering, as excess moisture can create a hospitable environment for both pests and diseases.

By staying proactive and following these preventive measures, you can help keep your microgreens healthy and thriving.
