As a microgreens farmer, I’ve had the privilege of turning a passion into a thriving business. Microgreens are delicate, vibrant, and packed with nutrients, but knowing when and how to harvest them can make all the difference in quality, yield, and flavor. In this guide, I’ll walk you through everything you need to know about harvesting microgreens, from timing to tools, regrowth, and storage—sharing practical tips based on my experience.

1. Introduction: Why Proper Harvesting Matters

Harvesting microgreens at the right time and using the right techniques is key to maintaining their flavor, freshness, and nutrient content. If you harvest too early, your microgreens might not have developed enough to deliver the punch you’re looking for. Harvest too late, and you risk bitterness or tough stems.

In my early days of growing microgreens, I didn’t realize how much the timing and method of harvesting could affect the final product. But as I grew more experienced, I learned the value of harvesting correctly—not just for taste but also for maximizing yield and shelf life.

Let me take you through everything I’ve learned about harvesting microgreens so you can avoid the mistakes I made early on.

2. When to Harvest Microgreens

The timing of your harvest is critical. While different varieties have their own ideal harvest windows, one general rule I follow is to harvest microgreens once they’ve developed their first set of true leaves (usually 7–14 days after planting, depending on the variety).

Here are the signs to look out for in some of the most common varieties:

Broccoli Microgreens

Broccoli microgreens are among the most popular and nutritious. They’re ready to harvest when they’re about 2–3 inches tall and have developed their first true leaves. Typically, this happens around 7–10 days after germination. Be careful not to wait too long, or they may lose some of their tender flavor.

Sunflower Microgreens

Sunflower microgreens are thicker and more substantial than some other varieties. You’ll know they’re ready to harvest when they’re about 3–4 inches tall, and you can see their first set of leaves. This usually takes around 10–12 days. It’s best to harvest them before they become too woody.

Pea Microgreens

Pea microgreens are a favorite for their sweet, crisp taste. These should be harvested when they’re about 4–5 inches tall, usually around 12–14 days after planting. Waiting too long can lead to tougher stems.

Pro Tip: Always check the specific variety you’re growing for the exact days to harvest, as this can vary slightly depending on your environment and growing method.

3. How to Harvest Microgreens

Once your microgreens are ready to harvest, the method you use will determine the quality of your final product. I’ve tried many different tools and techniques, and here are the best practices that have worked for me.

Best Tools for Harvesting Microgreens

You don’t need expensive equipment to get started, but having the right tools can make the process easier and more efficient. Here are a few tools I recommend:

  • Sharp Scissors or Knife: A clean, sharp tool ensures you get a smooth cut, which helps your microgreens stay fresh longer.
  • Quick Cut Greens Harvester: For larger harvests, this tool is a game changer. It speeds up the process and ensures a consistent cut.
  • Harvest Trays: A shallow tray can help you transport your freshly cut microgreens without damaging them.

Quick Cut Harvesting Methods

The easiest way to harvest is to gently lift the greens with one hand and cut with the other. Cut just above the soil level, leaving behind the roots. Avoid pulling the greens out of the soil, as this can bring unwanted dirt and debris with them.

For those growing microgreens commercially or in larger quantities, using a quick cut greens harvester can save you a lot of time. It allows you to harvest an entire tray in a fraction of the time it would take manually.

Pro Tip: Harvest your microgreens early in the morning or during cooler parts of the day to preserve their freshness and flavor.

4. Post-Harvest: Will Microgreens Regrow?

One of the most common questions I get asked is whether microgreens can regrow after harvest. The short answer is: it depends.

Some varieties, like pea and sunflower microgreens, may give you a second, smaller harvest if you leave part of the stem intact. However, most microgreens do not regrow once cut. Microgreens like broccoli, radish, and arugula typically won’t regenerate after harvesting because the growth energy is focused in the initial shoot.

If you want continuous harvests, I recommend sowing new seeds on a regular schedule so you always have a fresh batch coming up.

Pro Tip: If you’re looking to regrow microgreens, try experimenting with varieties that are known for multiple harvests, like pea shoots. Keep in mind that the second harvest is often less robust than the first.

5. How to Store Microgreens After Harvest

Proper storage is crucial if you want to keep your microgreens fresh and full of nutrients. Here’s how to ensure they stay crisp and flavorful after harvest:

  • Keep Them Dry: Microgreens are sensitive to moisture. After harvesting, gently pat them dry with a paper towel to remove any excess water.
  • Use Airtight Containers: Store your microgreens in an airtight container lined with a dry paper towel. This will absorb any moisture and help them stay fresh longer.
  • Refrigerate Immediately: Microgreens are best stored in the refrigerator at a temperature between 32°F and 40°F. This helps maintain their crispness and prevents wilting.

Stored properly, microgreens can last up to a week in the fridge. However, they’re most nutritious when eaten within a few days of harvest.

Pro Tip: If you notice any wilting or moisture buildup in the container, swap out the paper towel and make sure the greens aren’t packed too tightly.

6. Specialized Equipment for Commercial Harvesting

As your microgreens business grows, you may find that manual harvesting becomes time-consuming. Investing in specialized equipment can help you scale your operations efficiently.

Some equipment I recommend for larger-scale harvesting includes:

  • Farmers Friend Microgreens Harvester: This is a fantastic machine that allows you to harvest trays quickly and efficiently, especially when you’re working with large quantities.
  • Hamill Microgreens Harvester: Another option for commercial growers, this machine makes the harvesting process smoother and ensures a clean cut every time.

When you invest in the right tools, you’ll save time and increase your yield, helping your business grow faster.

7. Conclusion: Maximizing Your Microgreens Yield

Harvesting microgreens might seem simple, but mastering the right timing and technique can drastically improve the quality of your crops. Whether you’re a home gardener or a commercial grower, following these tips will help you get the most out of your microgreens.

Remember, it’s all about patience and precision—waiting for the right moment to harvest and using the best tools to do so. And don’t forget, proper storage is key to keeping your greens fresh and nutritious after harvest.

As a successful microgreens farmer, I can tell you that the extra attention you give during the harvesting process will pay off in better-tasting, longer-lasting microgreens. Happy harvesting!
