How Do You Know When Microgreens Are Ready? 3 Essential Visual Cues to Harvest at Peak Flavor

how do you know when microgreens are ready

Have you ever watched a sunrise and wondered exactly when the night turns into day?

Just like that subtle, beautiful transition, knowing when to harvest microgreens is a delicate art. It’s crucial for capturing their full potential.

Generally, microgreens are ready when they are 1-3 inches tall, within 7-14 days after sowing, as they reach the true leaf stage.

But, it’s not just about counting days; it’s about reading nature’s signs.

In my journey with these tiny greens, I’ve learned that each variety whispers its readiness in unique ways. This article will guide you through understanding these visual cues, ensuring you harvest at that perfect moment when flavour, texture, and nutrition are at their peak.

Identifying the Right Time to Harvest

Understanding Microgreens Growth Stages

It’s essential to understand the different growth phases of microgreens to know when they are ready for harvesting. Here’s a general timeline of microgreens growth:

Germination Stage: The journey of a microgreen starts with the germination stage, immediately after sowing the seeds. This initial phase is all about the magic happening beneath the soil’s surface. The seeds, once in contact with water, start absorbing moisture and nutrients, initiating growth. During this stage, the seeds swell, and the outer shell breaks open, allowing the first sign of life—a tiny root—to emerge.

However, microgreens are not ready for harvest at this stage. They are in their infancy, focusing on developing strong roots and a sturdy base for the growth that’s to come. While there’s a certain excitement in seeing those first signs of life, patience is key here.

Cotyledon Stage: Next comes the cotyledon stage. This is when the magic starts to become visible above the soil. The first leaves, known as cotyledons, make their debut. These are not the true leaves of the plant but rather part of the seed’s embryo. They often bear a simple shape and are different from the leaves that follow.

In some cases, microgreens can be harvested at this stage. For certain varieties, the cotyledons offer a tender texture and a mild flavour that’s quite appealing. However, I prefer to wait a bit longer. Allowing the microgreens to grow past the cotyledon stage often enhances their flavours and yields a more abundant harvest.

True Leaf Stage: Finally, we arrive at the true leaf stage. This is when microgreens start to show their true colours—literally. The second set of leaves, known as the true leaves, appear during this phase. These are the leaves specific to the plant variety and are often more intricate, colourful, and flavorful than the cotyledons.

As a home gardener, I would recommend harvesting microgreens at the true leaf stage. The flavours are at their peak, offering a more intense and varied taste experience. The nutritional value is also optimized, with the greens packing a powerful punch of vitamins, minerals, and antioxidants. This is the stage where the unique characteristics of each variety—be it the spicy zing of radish greens or the nutty richness of sunflower microgreens—truly shine.

How Do You Know When Microgreens Are Ready? 3 Visual Cues for Optimal Microgreens Harvest

Let’s dive into how you can tell when your microgreens are shouting, “I’m ready!” It’s all about looking for the right signs. Let’s break it down:

  • Leaf Development

First up, keep an eye on those true leaves. When they fully unfurl and show off their unique shapes, it’s like they’re waving at you, saying they’re good to go. You want those leaves to be vibrant and healthy.

  • Height and Density

Next, let’s talk about height and how close they are with their neighbours. Your microgreens should stand tall, about 1-3 inches, depending on what you’re growing. But it’s not just about how high they reach; it’s also about not being too crowded.

  • Color Intensity

Finally, let’s look at their colour! Most microgreens put on a vivid show when they’re at their best. They should be bright and consistent, really showing off what makes them special. But remember, each type of microgreen has its own unique colour palette.

Picking Your Greens: Harvest Times for Different Microgreens

Each type of microgreens has its own schedule and unique taste. Let’s explore some popular varieties and figure out when they’re ready to join your meals!

Mustard Microgreens For a spicier touch, mustard microgreens are your go-to. They mature in 8-12 days and have a bit more zing than their full-grown counterparts.

Broccoli Microgreens These are super nutritious and easy to grow. Taking about 9-14 days to harvest, they taste somewhat like cabbage and other mild veggies.

Radish Microgreens With a growth pattern similar to broccoli, radish microgreens are ready in under 12 days. They add a peppery punch to any dish.

Garden Cress Microgreens A relative of watercress, this herb is ready in 10-12 days. It’s got a peppery, slightly bitter taste.

Rocket Microgreens These greens bring the same peppery flavour as their full-grown form. Ready in 10-14 days, they’re a quick grower.

Basil Microgreens Taking a bit longer at 16+ days, basil microgreens are worth the wait. They offer a richer taste compared to the adult plant.

Remember, you can grow microgreens from almost any herb or vegetable. Play around with different types to find your favourites. Experimenting with a variety of microgreens that have different harvest times will broaden your flavour spectrum. Trust me, the longer wait for some (like carrot microgreens) is absolutely worth it.

Snip and Savor: Techniques for Perfect Microgreens Harvest

Gathering Harvesting Materials

Before you begin harvesting your microgreens, gather the necessary materials. You’ll need a sharp knife or a pair of scissors, a clean container or a tray, and optionally, a salad spinner for drying the harvested microgreens.

  1. Sharp knife or scissors: These help in cutting the microgreens just above the soil line without damaging them.
  2. Clean container or tray: Used to collect and store the harvested microgreens.
  3. Salad spinner (optional): This can be used to dry the microgreens after washing them.

Proper Technique for Picking Microgreens

To harvest microgreens effectively, follow these steps:

  1. Inspect the microgreens: Before cutting, ensure there are no signs of mould or disease.
  2. Gentle Grip: Carefully hold the stem of the microgreens just above the soil. Remember, they’re delicate, so be gentle. You don’t want to squash those tender leaves.
  3. Cut the microgreens: Using a sharp knife or scissors, gently cut the stems just above the soil line. Be careful not to pull the microgreens, as this might uproot them.
  4. Stems Included: Cut the stems along with the leaves. Why? Because it keeps the leaves together and adds a bit more crunch to your dish.
  5. Harvest as Needed: Only cut what you need for your meal. The rest can keep growing for your next harvest.

Washing and Drying (Optional)

  • Rinse the microgreens: If you’ve grown your microgreens in soil, wash them gently to remove any dirt. However, if you’ve used other growing methods, washing might not be necessary.
  • Dry the microgreens: If you washed the microgreens, use a salad spinner or a clean towel to gently remove excess water

Frequently Asked Questions

What are the signs of mature microgreens?

When microgreens are ready to harvest, they’ll display a few key characteristics. Firstly, they’ll have developed their first set of true leaves, which look different from the initial seed leaves. Additionally, their stems will be sturdy and their leaves a vibrant green colour. Some microgreens also show signs of maturity with the appearance of intense flavours.

How long does it typically take for microgreens to be ready?

The time it takes for microgreens to be ready varies depending on the type. Generally, they can take anywhere from 7 to 21 days from seed to harvest. For example, radish microgreens can be ready in as little as a week, whereas others might take longer. Make sure to keep an eye on your microgreens to ensure they’re progressing well. You can find more information about this in the Microgreens Growing Guide.

What height should microgreens reach before harvesting?

When microgreens are ready for harvesting, they’ll usually be around 2 to 5 cm in height. This height allows for optimal flavour and nutritional value, which is why microgreens are such popular additions to salads and dishes. Check out the BBC Gardeners World Magazine for more details on growing and harvesting microgreens.
