Will Microgreens Regrow? Unlocking the Joy of a Second Harvest (And Why It’s Not Always Possible)

will microgreens regrow

Ever wondered if your freshly snipped microgreens can spring back to life?

As a fellow microgreens enthusiast, I’ve often wondered if microgreens will regrow, surprising us by springing back to life, ready to offer another round of harvest in just a week.

The simple answer is that some microgreens can regrow, but the majority won’t.

When you harvest most microgreens, you’re cutting them right above the soil line, taking the leaves needed for photosynthesis and plant growth.

It’s important to note that there are a few exceptions, such as pea shoots, which have been known to regrow after cutting. The regrowth process, however, might take longer and result in less tender and flavourful greens compared to a fresh batch.

So, let’s delve into this intriguing world of microgreens and discover which ones can offer us more than just a single harvest.

What Are Microgreens? – A Short Reminder

If you’re here, chances are, you’re already somewhat familiar with microgreens. But let’s take a moment to revisit the basics, shall we? Microgreens are essentially the young versions of various vegetables and plants, harvested in their infancy.

Each microgreen consists of a simple structure: roots, a stem, a pair of cotyledons (those first leaves that emerge from the seed), and sometimes, the beginnings of true leaves. These greens might be tiny, but they’re a condensed burst of nutrients and flavours!

What makes microgreens unique is their harvest time. Unlike their fully-grown counterparts, these little wonders are typically ready for harvest shortly after their first leaves make an appearance. The harvesting process is a gentle yet decisive one – snipping the stems just above the soil line.

Understanding the Lifespan of Microgreens

The life of a microgreen is, by nature, fleeting. It begins with a seed, cradled in the soil, awakening to life with the right mix of moisture and warmth. Within just a few days, you’ll witness the first signs of growth – a process known as germination. This is where the magic starts, as tiny roots anchor into the soil while stems reach upwards, eager for light.

As the days progress, usually between the 7th and 14th day, the cotyledons – the first set of leaves – unfurl. These are not the true leaves of the plant, but they’re the first hint of greenery, a promise of what’s to come. In this stage, microgreens are at their peak in terms of flavour and nutrient density.

The growth cycle of microgreens is notably short. In most cases, they are ready for harvest just after these cotyledons have fully developed, and right before the true leaves emerge. This is typically within 1 to 3 weeks from sowing, a stark contrast to their mature counterparts which take several weeks or months to reach harvest.

The Big Question: Will Microgreens Regrow After Cutting?

To understand why most microgreens don’t make a comeback post-harvest, we need to dive into the very essence of their beginnings. Each seed of a microgreen is a tiny vault of energy – just enough to push forth the first set of leaves, the cotyledons. This initial burst of life is crucial for the plant’s early development. But here’s the catch: once these first leaves are harvested, the energy stored in the seed is essentially depleted. There’s nothing left in the tank for a second round of growth.

This means that for the vast majority of microgreens, the journey ends with the first harvest. The likes of Radish, Cress, Broccoli, and Sunflower microgreens, despite their vigorous start, won’t regrow after cutting.

Now, about the exception. A few resilient species like peas do offer a glimmer of hope. They occasionally defy the odds and sprout anew. But let’s be clear – this regrowth is sporadic and not something to rely on. As a seasoned gardener, I’ve observed these rare occurrences, but they’re more of a pleasant surprise rather than a consistent expectation.

Exceptions to the Rule: Microgreens That Can Be Regrown

There are always exceptions to the rule, and this is particularly true when it comes to the potential for regrowth. While most microgreens bid farewell after their first harvest, a select few hold the potential for a second act, challenging the norm and offering a delightful surprise to the persistent gardener.

The standout star among these resilient varieties is the pea microgreen. Pea microgreens, with their robust and vigorous growth, harbour a secret power – the ability to regrow under the right conditions. Unlike their counterparts, peas store a bit more energy in their larger seeds, giving them a fighting chance to sprout new shoots even after being harvested.

But why peas? The key lies in their natural growth habit and the structure of their seeds. Pea seeds are relatively large and packed with nutrients, providing enough energy reservoir to potentially fuel a second growth spurt. When you harvest pea microgreens, if done carefully, you leave behind a portion of the stem with nodes that have the potential to sprout new shoots.

However, it’s important to temper expectations. The regrowth of pea microgreens is not guaranteed, and even when it does happen, the second crop might not be as robust or flavorful as the first. The new shoots tend to be more spindly, and the leaves may not develop the same tender quality. But for those of us who revel in the miracles of gardening, the chance to see new life emerging from a harvested tray is a joy in itself.

Successfully Regrowing Pea Microgreens: A Detailed Guide

Regrowing pea microgreens might seem like a bit of a gardening magic trick, but with the right know-how, you can coax these resilient little plants into a second round of growth. Here’s how to do it:

Careful Harvesting is Key

When it’s time to harvest your pea microgreens, remember that precision is everything. You need to make a strategic cut – just above the first little leaf that emerges from the stem near the root. This leaf is essential; it’s going to help absorb sunlight and convert it into energy for new growth. So, grab those sharp scissors and snip carefully.

Maintain the Perfect Environment

Pea microgreens are a bit picky about their growing conditions, especially if you’re aiming for round two. After harvesting, leave the roots undisturbed in their cosy soil. They need stability to regrow.

Moisture and Air: Balancing Act

Now, ensure the soil remains moist, but not overly wet. Think of maintaining a nice, humid environment without making it soggy. And here’s a pro tip: good air circulation is crucial. It helps prevent mould, which can be a real party pooper in the microgreen world.

Sunlight: The Natural Energy Drink

Sunlight is to pea microgreens what coffee is to some of us – an absolute must. After the first harvest, place them in a spot where they can soak up gentle sunlight or bright, indirect light. This is their charging station.

Patience Pays Off

Here’s where your patience really counts. Give your microgreens time to do their thing. Keep an eye on the soil and the light, and soon enough, you might start seeing new shoots making their way up.

To Fertilize or Not?

Normally, pea microgreens don’t beg for fertilizer, but if you want to give them a little extra boost, a light mist at the start can work wonders. Just remember, it’s not essential for the regrowth process.

Is Microgreen Regrowth Worth It?

The idea of regrowing microgreens can be tempting. It’s all about getting the most out of every tray, right? While you might find yourself successful in coaxing a few extra greens to life, it’s important to note that these are often late sprouters, not a second crop from the original plants.

Fresh Starts Over Second Chances

Both at home and commercially, the most efficient approach usually involves starting anew. After a harvest, the old roots and soil are cleared out, making way for fresh seeds and a new beginning. This cycle ensures a steady supply of vibrant, nutrient-rich microgreens without the uncertainty and diminished returns of regrowth.

The Bottom Line

In essence, while the idea of regrowing microgreens is appealing, it’s generally more productive and rewarding to channel your efforts into nurturing a new batch. This approach not only saves time and resources but also guarantees the high quality and abundance that microgreens are cherished for.

What If You Let Microgreens Keep Growing?

Curious about what happens if you don’t harvest your microgreens right away? Well, it’s like watching a mini-drama unfold. Let’s explore what happens when you let these tiny greens grow up a bit.

The Transformation Journey

When you let microgreens grow past their salad days, they start to mature into something quite different. They stretch out, grow true leaves (the real deal, not just the baby ones), and get stronger stems.

Taste and Texture Makeover

As they grow, their whole vibe changes. The flavor? It gets bolder, sometimes even a bit too bold for some tastes. And the texture? They lose that delicate, tender quality and get a bit tougher. It’s like biting into a young, tender spinach leaf and then trying a mature leaf – same plant, but a whole different experience.

Colours Fade, Nutrients Shift

Remember those colours that made your microgreens look so vibrant? As they grow, these colours tend to fade, like a photograph left in the sun. Also, the nutrient profile changes. They are still good for you, but in a different way than those young microgreens.

Baby Greens vs. Microgreens

Some folks like to let their microgreens grow into baby greens or young plants. It’s totally fine, and I would actually encourage you to try and see which stage is your favourite!

Space: The Final Frontier

Here’s a heads-up though: microgreens are usually sown close together, cosy like a crowded beach. But if you want to let them grow, they’ll need more elbow room – bigger stems, more root space. I usually notice a point at which they start yellowing and wilting because they are becoming overcrowded and competing for resources.

Know Your Greens

If you’re thinking of letting your microgreens grow up, do a bit of homework first. Each variety is different. Understanding their full-grown flavour and best harvesting time can make a big difference. You want to catch them at their peak – for the best taste, texture, and nutrients.

Frequently Asked Questions

Can you harvest microgreens multiple times?

Most microgreens can only be harvested once. When you cut them just above the soil, you remove most of the leaves, which are necessary for photosynthesis. This makes it difficult for them to regrow.

What is the regrowth rate of microgreens?

The regrowth rate for the majority of microgreens is quite low. A few varieties may regenerate, but overall, it’s not a common trait among microgreens. As previously mentioned, cutting the leaves for harvest hinders their ability to undergo photosynthesis and grow back.

Do all varieties of microgreens regrow?

No, not all microgreens regrow after harvesting. Some microgreens may regrow, but most won’t.

How to encourage regrowth in microgreens?

While most microgreens don’t regrow, you can follow specific practices to increase the chances of regrowth. These might include water and nutrient management, adequate spacing, and appropriate harvesting methods. However, it’s essential to remember that regrowth is not guaranteed.

What factors affect microgreens’ ability to regrow?

Factors affecting microgreens’ regrowth include the plant variety, how it is harvested, and the general growing conditions such as light, temperature, and nutrients provided. Harvesting methods that preserve more of the plant’s foliage could potentially improve the chance of regrowth.

Are there specific microgreens that can be harvested more than once?

Yes, there are some varieties of microgreens that may be able to be harvested more than once. The main example is pea microgreens. However, it is crucial to remember that it’s not very common among microgreens.
