How to Start Growing Microgreens Easily at Home

Why Grow Microgreens at Home?

If you’ve ever wanted to grow your own fresh food but felt intimidated by gardening, microgreens are the perfect place to start. These tiny, nutrient-packed plants are incredibly easy to grow, even if you don’t have a lot of space or experience. All you need is a shallow tray, some seeds, and a sunny spot or grow light to get started. In just a week or two, you can have a fresh harvest of vibrant greens ready to brighten your meals and boost your nutrition. Whether you’re looking to add a pop of flavor to your cooking or just want the satisfaction of growing something yourself, microgreens make it easy and rewarding.

What You’ll Need to Get Started

One of the best things about growing microgreens is how simple and accessible it is.

• You don’t need a garden, fancy tools, or a green thumb.
• All that’s required is just a few basic supplies and a little enthusiasm.

Here’s what you’ll need to set yourself up for success:

• Trays or Containers
  You’ll need a shallow tray or container. Recycled food trays, baking pans, or seedling trays all work well. If you’re using something without drainage holes, you’ll need to be extra careful not to overwater. Overwatering is a common problem, but following our guide here, it’s one you won’t face.

• Soil or Growing Medium
  Microgreens can grow in a variety of mediums, but soil is the most common and beginner-friendly. Look for a light, well-draining potting mix. I use Seedling Starter mix., and have been for a few years now. If you prefer a soil-free option, you can try coco coir, peat moss, or even hydroponic mats designed for microgreens. The benefit of going with natural matting is that after harvesting, the mats can be dropped into a composting vessel. You can also grow your microgreen seeds in mason jars that have a vented lid!
• Seeds
  Not all seeds are created equal when it comes to microgreens. Look for seeds specifically labeled for microgreens or sprouting to ensure quality and food safety. Popular options include alfalfa, radish, pea, broccoli, and mustard seeds. My next article goes more in depth regarding selecting the best microgreen seeds with which to get started.

• Light Source
  Microgreens thrive with plenty of light. A sunny windowsill can work. Relying on the sun’s rays can be troubling. Also, seedlings can get a little “leggy” as they try to reach the distant sun’s rays. If you want consistent growth or lack natural light, a simple grow light is a great investment.

• Watering Tools
  A spray bottle is ideal for watering microgreens. It gives you control over moisture levels without over-saturating the soil or disturbing the seeds.
• Optional: A Cover for Germination
  Covering your tray for the first few days helps seeds germinate evenly. You can use another tray, a lid, or purchase some square trays with mated humidity dome covers. Once the seeds sprout, remove the cover to let them grow freely. Remember, all that a seedling needs to produce its first set of leaves is within its seed. It is literally an “Add Water For Life” being!

With these basics, you’re ready to start growing microgreens at home. You don’t need to spend a lot or have any special skills—just a willingness to experiment and enjoy the process!

Step-by-Step Growing Process

Growing microgreens is as straightforward as it gets. It’s perfect for beginners and seasoned gardeners alike. Follow these simple steps, and in just a couple of weeks, you’ll have your own mini garden of vibrant, flavorful, and darn healthy greens.

1. Choose Your Seeds

Start by selecting seeds that are ideal for microgreens. Popular choices like alfalfa, cilantro, pea, and basil are fast-growing and packed with flavor. Look for seeds labeled for microgreens or sprouting to ensure the best results.

2. Prepare Your Tray

Take a shallow tray or container and fill it with about 1–2 inches of soil or your chosen growing medium. Smooth the surface so it’s even, but don’t pack it down too tightly—roots need room to grow. If you’re using soil-free options like coco coir or a grow mat, prepare them according to the package instructions.

And if you’re opting for the Mason jar method, you’ll want to let your seeds soak overnight. The growing process is a little different when growing inside a vented jar.

3. Plant Your Seeds

Sprinkle the seeds evenly across the surface of the soil. They can be close together, but avoid overcrowding to ensure good airflow and healthy growth. Gently press the seeds into the soil to make contact, but there’s no need to bury them.

4. Water the Seeds

Use a spray bottle to mist the seeds until the soil is evenly moist but not waterlogged. If you’re using a container with drainage holes, let any excess water drain away.

5. Cover and Germinate

Cover the tray with another tray, a lid, or a damp paper towel to create a dark, humid environment. This helps the seeds germinate quickly and evenly. Check daily to ensure the soil stays moist—give them a light misting if needed.

6. Expose to Light

After 3–5 days, when you see the seeds sprouting, remove the cover and place the tray in a well-lit area. A sunny windowsill works, but a grow light ensures consistent results. Keep the light source close to the greens for the best growth.

7. Water and Watch Them Grow

Continue to mist your microgreens daily or as needed to keep the soil moist. Be careful not to overwater, as this can lead to mold or root rot. Within a few days, you’ll notice your greens growing taller and more vibrant.

8. Harvest Your Microgreens

When your microgreens are about 1–3 inches tall and have their first set of true leaves (usually 7–14 days after planting), they’re ready to harvest. Use sharp scissors to snip them just above the soil line.

By following these steps, you’ll have fresh, homegrown microgreens in no time. It’s a quick, rewarding process that can fit into any lifestyle—whether you’re growing for nutrition, flavor, or just for the joy of it!

How to Harvest Microgreens

Harvesting microgreens is one of the most satisfying parts of the growing process. With just a few simple steps, you’ll have a fresh batch of greens ready to enjoy. Here’s how to do it while keeping everything clean and fresh for maximum shelf life.

1. When to Harvest

Most microgreens are ready to harvest 7–14 days after planting, depending on the variety. The best time to harvest is when the greens are about 1–3 inches tall and have developed their first set of true leaves. Check your microgreens daily—waiting too long can lead to tougher stems or diminished flavor.

2. Prepare for Harvest

• Harvest in the morning: The greens will be at their freshest and most hydrated.
• Clean tools: Use a sharp pair of scissors or a knife, and make sure they’re sanitized to prevent contamination. Wipe the blades with rubbing alcohol or wash them with hot, soapy water.
• Wash your hands: Always handle microgreens with clean hands to maintain food safety.

3. How to Cut

Hold a small section of the greens upright and use your scissors to snip them just above the soil line. Be gentle to avoid bruising the delicate stems. If you’re using a soil-free medium like a grow mat, cutting is even easier—just trim close to the base.

4. Cleaning Your Microgreens

After harvesting, gently rinse the microgreens in cool water to remove any dirt or debris. Use a salad spinner or lay them out on a clean kitchen towel to remove excess moisture. Keeping them dry helps extend their shelf life.

5. Storing Your Microgreens

To keep your microgreens fresh:

• Place them in an airtight container lined with a paper towel to absorb any remaining moisture.
• Store the container in the crisper drawer of your refrigerator, where they’ll stay fresh for up to 5–7 days.
• Avoid sealing them if they’re still damp, as this can lead to spoilage.

6. Pro Tip for Longevity

If you plan to use your microgreens immediately, they’ll taste their absolute best when freshly cut. For longer storage, consider only harvesting what you need. Leave the rest to continue growing in the tray until you’re ready for more.

By following these steps, you’ll not only enjoy the freshest and most flavorful microgreens but also maximize their shelf life—perfect for sprinkling onto meals throughout the week. Up next, we can dive into troubleshooting common issues to ensure your next crop is even better!

Troubleshooting Common Issues

Growing microgreens is a simple and rewarding process, but even the best setups can encounter hiccups. Don’t worry, most problems have straightforward solutions. Here’s how to address some of the most common challenges growers face:

1. Mold and Mildew

• Symptoms: White, fuzzy patches appear on the soil or around the base of your microgreens.
• Causes: Overwatering, poor air circulation, or overcrowding seeds.
• Solutions:
  • Reduce watering—keep the soil moist but not soaked. Skip a day’s watering.
  • Improve airflow by using a small fan near your trays.
  • Ensure trays aren’t too crowded; thin out seeds if needed.
  • Sprinkle a light dusting of cinnamon on the soil—it’s a natural antifungal!
• If your microgreens are showing white fungal growth, you can use a diluted solution of food-grade hydrogen peroxide to help combat the issue; simply soak the seeds in a 3% hydrogen peroxide solution for a short period before planting to potentially prevent mold growth, or lightly mist the affected areas with a diluted solution if the mold has already appeared.

2. Uneven Growth

• Symptoms: Some greens are taller or healthier than others in the same tray.
• Causes: Uneven seed distribution or inconsistent lighting.
• Solutions:
  • Sow seeds as evenly as possible. A seed shaker can help with this.
  • Rotate trays daily if using natural light to ensure all areas get equal exposure.
  • Consider using a grow light for consistent results.

3. Leggy or Weak Growth

• Symptoms: Microgreens are tall, thin, and floppy.
• Causes: Insufficient light or too much heat.
• Solutions:
  • Provide a stronger light source, like a full-spectrum grow light, and keep it close to the greens (about 2–4 inches away).
  • Avoid placing trays in overly warm areas, as heat encourages rapid, weak growth.

4. Poor Germination

• Symptoms: Seeds don’t sprout or germinate unevenly.
• Causes: Old seeds, improper watering, or incorrect temperatures.
• Solutions:
  • Use fresh, high-quality seeds labeled for microgreens.
  • Maintain consistent moisture during germination (not too dry, not too wet).
  • Keep trays in a warm spot (65–75°F) until the seeds sprout.

5. Yellow or Pale Microgreens

• Symptoms: Greens are light yellow instead of vibrant green.
• Causes: Lack of light after germination.
• Solutions:
  • Once seeds sprout, immediately expose them to bright, indirect light or a grow light.
  • Keep them under light for at least 12–16 hours a day.

6. Overwatering or Root Rot

• Symptoms: Soil looks soggy, greens droop, or roots appear slimy.
• Causes: Too much water or poor drainage.
• Solutions:
  • Use trays with drainage holes, or ensure water isn’t pooling at the bottom.
  • Water lightly with a spray bottle instead of pouring water directly onto the soil.
  • Allow the soil surface to dry slightly between waterings.

7. Pests

• Symptoms: Small bugs (like aphids or gnats) on your microgreens.
• Causes: Overwatering or contaminated growing areas.
• Solutions:
  • Keep your growing area clean and free of decaying plant material.
  • Use sticky traps for gnats or gently rinse aphids off with water.
  • For severe infestations, consider natural pest control methods like neem oil (be cautious if consuming the microgreens).

8. Seeds Sticking to Microgreens

• Symptoms: Seed hulls remain attached to the leaves, making it hard to clean.
• Causes: Lack of moisture during germination.
• Solutions:
  • Gently mist the seeds during the germination phase to soften the hulls.
  • If hulls remain, use your fingers or a soft brush to remove them manually.

Storing and Using Your Microgreens

Once you’ve harvested your fresh batch of microgreens, the next step is making sure they stay crisp, vibrant, and delicious until you’re ready to use them. With the right storage methods and a little creativity in the kitchen, your microgreens will be a versatile addition to meals all week long.

How to Store Microgreens

1. Dry Them Properly
   After harvesting and rinsing your microgreens, ensure they’re thoroughly dry to prevent excess moisture, which can lead to spoilage. Use a salad spinner or lay them on a clean kitchen towel to gently pat them dry.
2. Use Airtight Containers
   Place your microgreens in a plastic or glass container lined with a dry paper towel to absorb any lingering moisture. Avoid compressing them too tightly—they need a bit of airflow. I’ve also used sealable plastic bags with a paper towel inside. Works just fine, too.
3. Refrigerate Promptly
   Store the container in the crisper drawer of your refrigerator, where they’ll stay fresh for up to 5–7 days. Keep them away from overly cold spots that can cause wilting or freezing.
4. Harvest on Demand
   If possible, harvest only what you need for the day. Microgreens left in the tray often stay fresher longer than those stored in the fridge.

Enjoying Your Microgreens

Microgreens aren’t just pretty—they’re packed with flavor and nutrition, making them a versatile ingredient in the kitchen. Here are a few creative ways to enjoy them:

• Salads
  My second favorite way to eat my microgreens! Toss a handful of microgreens into a salad for a fresh, flavorful boost. They can act as the base or a garnish for extra texture.
• Sandwiches and Wraps
  My favorite way! Replace or complement lettuce with microgreens for a more vibrant, nutrient-packed layer in your sandwiches, wraps, or burgers. Sliced deli meat, mayo, a little wasabi, and a generous heaping of greens… So Good!
• Soups
  Sprinkle microgreens on top of soups just before serving to add a pop of color and a delicate flavor contrast.
• Smoothies
  Blend mild microgreens like sunflower or pea shoots into your smoothies for an extra dose of vitamins and minerals. I’ve not personally tried this. I’m one of the few people who really like V-8 and V-8 Splash, and I love making my own cold press green juice.
• Garnishes
  Use microgreens as a garnish for almost anything—omelets, pizzas, pasta dishes, or roasted veggies. They elevate the presentation and add a gourmet touch. You’ll find you will need to produce a LOT of microgreens as you begin to add them to all your food.
• Stir-Fries
  Add microgreens at the very end of cooking stir-fries for a burst of freshness that balances the warm, savory flavors.

Top Tips for Success

Growing microgreens is straightforward, but a few extra tips can take your greens from good to amazing. Here are my tried-and-true tricks to make the process even easier and more rewarding:

• Start with Easy Seeds
  If you’re just beginning, stick with fast-growing, reliable seeds like radish, alfalfa, or curated blends. These are forgiving and produce satisfying results quickly.
• Stagger Your Plantings
  To enjoy a continuous harvest, sow a new tray every 3–4 days. This way, you’ll always have fresh microgreens ready to use. If you run out of microgreens, you will be sad.
• Pay Attention to Light
  As their first set of leaves develop, microgreens love light! A sunny windowsill or a small grow light positioned above to the greens will keep them vibrant and healthy. Rotate your tray daily if using natural light to ensure even growth.
• Experiment with Varieties
  Don’t be afraid to try new seeds or mix different varieties in the same tray for a flavorful, colorful blend.
• Keep It Clean
  Sanitize your trays and tools between plantings to avoid mold or pests. A clean setup is essential for healthy microgreens. This is why Mason jars are particularly popular growing vessels, as they can just be washed in the sink easily.
• Hydration is Key
  Use a spray bottle to water evenly, keeping the soil moist (really, just damp) but never soggy. Overwatering is one of the most common mistakes, so keep an eye on moisture levels. If you start to see white moldy growth…
• Harvest with Care
  Use clean, sharp scissors to snip your greens just above the soil line. Handle them gently to avoid bruising their delicate stems and leaves.
