If you are a beginner to growing microgreens, you’re sure to have a few questions now and then.
Whether microgreens regrow is one of the most common questions that beginners have. Why stop with one batch of harvest if you can get more of it, right?
So, do microgreens regrow after cutting?
Certain types of microgreens regrow after your cut them. Leaving the lowest leaf uncut can help in regrowing the microgreens with the help of photosynthesis. Even after regrowth, the microgreens show shunted growth and are less tasty (and healthy) when compared with the first harvest. Note that majority of microgreens do not regrow.
Whether you can regrow microgreens or not, is it actually a good idea to so? What are the factors that affect regrowth? In this post, we discuss these questions and answer other important questions as well.
Do Microgreens Regrow After Cutting – A Detailed Explanation
Only a few microgreens regrow after you cut them for harvesting. Most of them don’t.
Even if microgreens regrow, you will not see the same level of growth in terms of look and taste. Most second-time growers have exhibited shunted growth which not the desired result.
In addition to shunted growth, the rate at which the microgreens grow is also very slow. So it takes more time to get greens that are not as good as the first batch of microgreens.
Another aspect where you see a big difference is in the taste. If you’re planning to grow microgreens commercially, then it is a good idea to stop with the first harvest.
If you’re going to produce not-as-good tasting second harvest microgreens, people are not going to be big fans of them, and it could negatively impact your business.
How To Regrow Microgreens After Cutting?
You can try regrowing microgreens by leaving the lowest (and healthy) on the stem while harvesting.
This way, the plant will continue doing photosynthesis and try growing from the cut portion.
There are a couple of factors that affect the regrowth of microgreens.
How good the regrowth of the microgreen is completely dependent on its ability to do photosynthesis.
By not cutting the lowest leaf, we are hoping that the leaf would continue doing photosynthesis and help in regrowing the microgreen.
This is also the reason why we don’t harvest all the leaves if you’re planning to regrow. The stem, in most cases, may have reached full growth and might not grow further.
So make sure you give your microgreen the best conditions for photosynthesis if you’re planning to regrow your microgreens.
Fighting Injuries and Infections
Once you cut a microgreen, you’ve done significant damage to the plant.
The original idea is to harvest once and put them aside. Now since you want to regrow them you should understand that the microgreen has to overcome a big injury to start growing again.
Molding is one of the most threatening issues when you’re trying to grow microgreens.
The chances of molding increases when you cut a microgreen. You should take measures to make sure that your harvested microgreen does not grow molds.
One of the best ways to make sure of it is to not water your microgreens to often. Just give your plant enough water and don’t overwater them. Moist conditions are very favorable for the development of molds.
Should You Regrow Microgreens? Is It Worth It?
The simple answer is No.
It is just not worth it.
You might want to regrow your microgreens for a number of reasons.
You might want to experiment a bit and see if you can get more out of the same tray. Or you could simply be doing a botanical experiment for all we know.
The reason why we say regrowing microgreens is not a good idea is because it defeats the purpose of microgreens from different angles.
- You will need to spend more time on regrowths than you would on a fresh batch of microgreens.
- It will not save you any money whatsoever
- It destroys the most enjoyed aspect of microgreens, its taste
- There is also no evidence that you will get the same amount of nutrients in your second batch of regrown microgreens
You will be spending your time and energy on growing shunted plants that take more time to grow and give you a lot less.
You could have spent the same time and energy on a new batch of microgreens, and the results would have been ‘n’ times better.
But hey, as we said, if you want to run an experiment and not doing it for commericial purposes, please do try and let us know your findings. We’d be happy to share the results with the world on your behalf.
Which Microgreens Regrow After Cutting?
We have listed more than 100 microgreens in our ‘types of microgreens‘ post, and we can confidently say that only a fraction of those types regrows.
Some of the know varieties that regrow are
Peas are the easiest ones to regrow. A lot of pea varieties grow well in the post-harvest stage and should be a good starting point if you’re up for experimentation.
Not all the microgreens on our list have been tested with regrowth. So feel free to experiment with different microgreens and see if they can regrow after you cut them.
Another point to note here is to not mistake late sprouting for regrowth. If you had overseeded the tray, then you might get some late bloomers on your tray. Do not mistake them for your second batch.
How To Reuse The Soil After Harvesting Microgreens
Reusing soil is one of the best things you can do after harvest.
The soil is enriched with nutrients, and you simply can’t throw it away. But using them for another batch of microgreens is also not a great idea as it can have microbes that can hinder the next batch’s growth.
So how do you reuse soil after harvest?
There are a couple of ways to do it.
Convert It Into Compost
Turning your reused solid into compost is one of the best things you can do.
This way, you’re not wasting your soil, and you’re turning them into super soil which would be more fertile than when you started with it.
Simply put your reused soil into a compost bin or a worm bag. The worms will take care of the rest. They will consume all the stems, and other microgreen remains on the soil.
The decomposition of the remains will enrich the soil and will make it incredibly fertile.
You can then use this soil for microgreens and would be surprised at how good this soil is after seeing your results.
Moreover, by doing this, you’re promoting organic farming, and that is an excellent way to go about sustainability.
Though this is not as effective as the first method, you can still make good use of this.
Simply turn over the soil after harvest into another tray.
The stems and roots will not be at the bottom of the soil and will provide the nutrients your microgreens need over time.
After turning the soil over, sow your seeds and put some soil on top of it. You can now continue growing your microgreen in your regular fashion.
Be aware that this is not fresh soil, and you will have microbes in it. It can hinder the growth of the microgreens and damage them in the later stages.
There is also a good chance of molding if the environment is too moist.
We prefer the composting method over this as you get super-fertile soil in the end.
How To Get The Best Out Of The First Harvest?
Keeping the experiments aside, one of the reasons people are interested in regrowing microgreens is to get the most of their tray.
But, as we said, regrowing is not a great idea and can result in inferior produce.
Here are some ways to nail the first harvest. This way you would be super happy with your microgreens and won’t even dream of regrowing.
1. Proper Drainage and Aeration
Do not overwater your microgreens.
While water is one of the essential ingredients, overwatering your microgreens can lead to several unnecessary problems.
Water stagnation can lead to a lack of oxygen, and this can help in the development of molds. Sometimes, overwatering can even destroy your microgreens.
One way to combat this is to have a proper drainage system.
You can also improve the aeration by using fans. This could also help in reducing the chances of mold formation.
2. Stop Overseeding
If you sow your seeds too close, then you may end up having fungus and similar headaches.
Be sure to make sure that seeds don’t overlap with each other.
You can also make use of this wonderful tool to find the right seed density for your microgreens.
3. Giving The Right Conditions
Give your microgreens the best chance to grow.
Provide it with the best medium, be it soil or water.
Make sure you water it just enough and provide all the things it needs to grow into a beautiful microgreen.
Also, use the right tools when growing microgreens. Some might be a bit expensive, but if you’re serious about your microgreen business, then it should be worth it.
Regrowing microgreens for commercial purposes is a bad idea.
You can try experimenting with your favorite microgreens and see if you can produce something with the same taste and growth levels. But that’s where it should stop.
Instead of wasting your time and energy on regrowing, you can do much better with a new batch of microgreens.
