The Importance of Timing
Harvesting microgreens at the right time is crucial for ensuring their taste, texture, and nutritional content are at their best. Unlike their mature counterparts, microgreens have a short growing cycle, typically ranging from 7 to 21 days, depending on the variety. Harvesting too early or too late can result in less flavor, diminished nutrients, or even a bitter taste.
Determining Readiness
1. True Leaves Stage: The first step in harvesting microgreens is to determine when they've reached the "true leaves" stage. After the initial cotyledon (seed leaves) have sprouted, the true leaves will emerge. These leaves will have a shape and appearance specific to the microgreen variety you're growing.
2. Size Matters: Microgreens should generally be harvested when they are about 1 to 2 inches tall. Some varieties, like basil or cilantro, may be slightly larger at harvest, but it's crucial to avoid waiting too long, as they can become tough or lose flavor.
3. Intense Flavor: A good indicator of readiness is the flavor profile. Taste a few leaves to ensure they have developed their characteristic taste. The flavor should be concentrated and intense but not overpowering.
4. Color Check: Examine the color of your microgreens. They should have vibrant, uniform coloration, which varies depending on the variety. Avoid harvesting if they appear pale or yellowish, as they may not have fully developed their flavor and nutrients.
The Right Tools for the Job
Once you've determined that your microgreens are ready for harvest, it's essential to use the right tools to ensure a clean and efficient process.
Clean Scissors or Shears
1. Scissors or Shears: Invest in a pair of clean, sharp scissors or garden shears specifically designated for harvesting microgreens. Dull blades can bruise the delicate leaves, affecting their quality.
2. Sanitization: Before you start, ensure that your scissors or shears are clean and sanitized. A quick rinse with isopropyl alcohol or hydrogen peroxide will help prevent contamination and potential disease transfer to your plants.
3. Precision Cutting: Position your scissors or shears just above the soil surface and make a clean, swift cut. Avoid tearing or pulling the plants, as this can damage the roots and soil structure.
Harvesting Techniques
Now that you have the right tools, let's explore some harvesting techniques that will help you maximize the quality of your microgreens.
Selective Harvest
1. Leaf by Leaf: If you prefer, you can selectively harvest individual leaves rather than the entire plant. This method allows you to enjoy a prolonged harvest from each planting.
2. Cut and Come Again: Some microgreen varieties, like lettuce or arugula, are well-suited for the "cut and come again" technique. Simply cut the greens just above the soil line, leaving a bit of the plant intact. They will regrow, allowing for multiple harvests.
3. Continuous Harvest: To enjoy a continuous supply of microgreens, stagger your plantings by a few days or weeks. This way, you can harvest a batch while the next is still growing.
Bulk Harvest
1. Full Harvest: If you prefer to harvest your entire tray or container of microgreens at once, follow these steps:
a. Use your clean scissors or shears to cut all the plants at the same height, just above the soil surface.
b. Gather the harvested microgreens in a bowl or container.
c. Sort and discard any damaged or discolored leaves.
d. Store the harvested microgreens in a cool, dry place until you're ready to use them.
Post-Harvest Care
Proper post-harvest care is vital to maintain the freshness and quality of your microgreens.
Rinsing
1. Gentle Rinse: It's a good practice to give your harvested microgreens a gentle rinse to remove any residual soil or debris. Use a fine-mesh strainer or place them in a bowl of cold water and swish them around.
2. Drain Excess Water: After rinsing, allow the microgreens to drain thoroughly. Excess moisture can lead to spoilage, so make sure they are almost dry before storing them.
Drying
1. Pat Dry: Gently pat the rinsed microgreens with a clean paper towel or kitchen towel to remove any remaining water droplets. Be careful not to crush or bruise the delicate leaves.
2. Air Drying: Alternatively, you can let them air dry by spreading them out on a clean, dry kitchen towel or paper towels. Ensure they are evenly distributed for efficient drying.
Storing Your Harvest
To prolong the freshness and shelf life of your harvested microgreens, proper storage is crucial.
Refrigeration
1. Refrigerator Storage: Place your dried microgreens in a clean, airtight container or a resealable plastic bag. Squeeze out excess air to minimize moisture and seal the container.
2. Temperature and Humidity: Store the container in the refrigerator at a temperature of around 32°F to 36°F (0°C to 2°C). This will help slow down the degradation process and maintain their quality.
3. Use Quickly: Microgreens are best enjoyed within a few days of harvest for peak flavor and nutrition. While they may stay fresh for up to a week when properly stored, their quality may decline over time.
Creative Ways to Enjoy Microgreens
Now that you've mastered the art of harvesting microgreens, it's time to put your fresh harvest to good use. Microgreens are incredibly versatile and can enhance the flavor and visual appeal of various dishes.

3. Garnishes: Use microgreens as garnishes for soups, omelets, and savory dishes. Their vibrant colors will make your plates look restaurant-worthy.
4. Smoothies: Add a handful of microgreens to your morning smoothie for an extra nutrient boost without altering the taste significantly.
