As a microgreens farmer, I know just how important it is to store microgreens properly to ensure freshness, flavor, and longevity. After years of trial and error, I’ve perfected my storage methods, which have been essential in keeping my microgreens business running smoothly. If you’re a grower or even just enjoy having microgreens at home, it’s crucial to know the best ways to store them to avoid waste and preserve their nutrients.
In this guide, I’ll share practical tips and methods for storing microgreens—whether you’re harvesting fresh from the soil or picking up a batch from the store.
Why Proper Storage Matters for Microgreens
Microgreens are highly perishable and begin to lose their freshness soon after harvest. If you don’t store them properly, they can wilt, lose nutrients, and even grow mold. Proper storage isn’t just about keeping them crisp; it also helps to maintain their taste, texture, and the vibrant color that makes them so appealing.
Microgreens are packed with vitamins, minerals, and antioxidants. However, improper storage can cause them to lose these beneficial properties, making proper techniques essential for anyone interested in maximizing the health benefits of these little greens.
Why Microgreens Spoil Quickly
Unlike mature greens, microgreens are harvested at a young stage, which means they have more delicate stems and leaves. Their high water content makes them particularly vulnerable to wilting and spoilage. Without the right storage method, you’ll find yourself tossing them out sooner than you’d like. Luckily, there are several ways to extend their shelf life.
How to Store Microgreens After Harvest
The first step to keeping microgreens fresh starts right after harvest. Whether you grow them yourself or purchase them, how you handle them immediately can make all the difference.
Step-by-Step: Harvesting and Storing Microgreens
- Harvest at the Right Time: Harvest your microgreens when they’re around 1-3 inches tall, typically after 7-21 days of growth depending on the variety. Use sharp, clean scissors to snip them just above the soil line.
- Rinse Gently: Once harvested, rinse the microgreens with cool, clean water to remove any dirt or debris. Be gentle; microgreens are fragile and rough handling can damage them, causing quicker spoilage.
- Dry Thoroughly: This step is critical. Moisture is the enemy when it comes to storing microgreens. After rinsing, spread them out on a clean towel or use a salad spinner to remove excess water. Allow them to air dry for a few minutes before moving on to storage.
- Choose the Right Container: Store the dried microgreens in an airtight container. This could be a glass or plastic container with a lid, or even a resealable plastic bag. Add a paper towel inside the container to absorb any excess moisture, which can cause rot or mold.
- Store in the Fridge: Once packed, place the container in the crisper drawer of your fridge. This area tends to have the ideal temperature and humidity levels for leafy greens.
Best Way to Store Microgreens in the Fridge
Storing microgreens in the fridge is the most common and effective way to preserve their freshness. However, there are a few tips to ensure they stay crisp and vibrant.
Ideal Temperature and Humidity
Microgreens should be stored at a temperature between 36°F and 40°F (2°C to 4°C) to slow down the spoilage process. If the temperature is too high, they will wilt and degrade faster. On the flip side, temperatures that are too low could freeze the greens, ruining their texture.
Humidity plays a significant role as well. Too much moisture in the fridge can cause mold growth, while too little can dry out your greens. That’s why the crisper drawer is the best spot, as it helps regulate humidity.
Containers That Work Best for Storing Microgreens in the Fridge
Choosing the right container is crucial for maximizing shelf life. Here are some effective options:
- Glass Containers: These are my personal favorite. Glass containers with tight-fitting lids create a perfect seal that helps maintain freshness while keeping out excess moisture.
- Plastic Containers with Ventilation: If you’re using plastic, ensure it has ventilation holes to allow some airflow. This helps prevent moisture buildup, which can lead to slimy greens.
- Resealable Bags: Another option is to use a resealable plastic bag, but be sure to squeeze out as much air as possible before sealing it. Adding a paper towel to the bag will help absorb any extra moisture.
Eco-Friendly Ways to Store Microgreens
In the world of sustainable farming, eco-friendly practices are key. Whether you’re running a microgreens business or just want to reduce waste at home, there are eco-conscious ways to store your greens without relying on single-use plastics.
Sustainable Storage Solutions
- Beeswax Wraps: These reusable wraps are a great alternative to plastic wrap or plastic bags. They keep microgreens fresh while reducing plastic waste. Wrap your microgreens in beeswax wraps and store them in the fridge.
- Silicone Food Storage Bags: These reusable, eco-friendly bags are perfect for keeping microgreens fresh. They’re airtight, washable, and can be used repeatedly, making them an excellent alternative to single-use plastic bags.
- Compostable Containers: Some companies now offer compostable storage containers made from biodegradable materials. These are a sustainable choice that doesn’t compromise on keeping your microgreens fresh.
- Cloth Bags: For short-term storage, you can use organic cotton or linen bags, especially for dry greens like pea shoots or sunflower greens. These bags allow for airflow while keeping your microgreens dry.
Storing Microgreens in Soil: Is It Possible?
Some people wonder whether they can store microgreens directly in the soil to extend their freshness. While it’s possible to keep microgreens in soil until you’re ready to harvest, it’s not the most practical long-term solution for most people. Here’s why:
The Pros and Cons of Storing Microgreens in Soil
- Pros:
- Microgreens in soil can continue to grow, allowing you to harvest fresh as needed.
- The soil can keep the roots hydrated, which may prolong the greens’ life.
- Cons:
- Soil storage requires more space and constant monitoring for water levels.
- Soil-grown microgreens are more prone to developing mold if overwatered.
- You’ll still need to rinse and dry them after cutting, which means they won’t necessarily last longer than if you harvested them all at once and stored them properly in the fridge.
If you prefer to harvest microgreens as you need them, storing them in soil can work for small-scale home growers. Just be aware that this method requires more care and attention.
How to Store Microgreens Seeds for Future Use
If you’re serious about growing microgreens long-term, you’ll want to store seeds properly to ensure they remain viable for future planting. Like microgreens themselves, seeds require the right conditions to stay fresh.
Best Practices for Storing Microgreens Seeds
- Choose the Right Container: Store your seeds in airtight containers to protect them from moisture. Glass jars with tight-fitting lids work well, or you can use vacuum-sealed bags.
- Keep Them in a Cool, Dark Place: Seeds should be stored in a cool, dry, and dark environment, such as a pantry, cupboard, or even the fridge. Ideal temperatures range between 32°F and 41°F (0°C to 5°C). Avoid areas with fluctuating temperatures, such as a garage or basement.
- Avoid Humidity: Moisture is the number one enemy of seeds. If seeds are exposed to humidity, they can sprout prematurely or develop mold. Including a silica gel packet in the storage container can help absorb excess moisture.
- Label Your Seeds: Always label your seeds with the date of purchase and the type of microgreens. This will help you track when you need to use them and ensure you’re planting the freshest seeds.
Properly stored, microgreens seeds can last for up to five years, depending on the variety.
How Long Can You Store Microgreens?
Now that we’ve covered all the different ways to store microgreens, how long can you actually keep them fresh? Here’s a quick breakdown based on the storage method:
- Fridge Storage: If stored properly in an airtight container with a paper towel to absorb moisture, microgreens can last anywhere from 7 to 10 days in the fridge.
- In Soil: If you opt to leave your microgreens growing in soil and harvest them as needed, they can last up to 2-3 weeks, but the flavor and texture may decline over time.
- Freezing: Though not ideal, some people freeze microgreens to extend their shelf life. However, this can affect the texture and taste. If you do choose to freeze them, they’ll last up to 6 months but are best used in smoothies or soups where texture is less of an issue.
Final Thoughts: Keep Your Microgreens Fresh and Tasty
Storing microgreens properly can make a world of difference in keeping them fresh, flavorful, and nutritious. Whether you’re running a microgreens business or just enjoy having them on hand at home, following the right storage methods can help you reduce waste and extend the life of your greens.
Remember, freshness starts at harvest, and it’s all about finding the right balance of temperature, humidity, and airflow. Whether you’re using eco-friendly storage solutions, keeping them in the fridge, or even experimenting with soil, proper storage ensures that you enjoy the maximum benefits of these tiny, nutrient-packed plants.
So go ahead, harvest those microgreens, store them well, and enjoy their freshness for days to come!
