Microgreens are known for their short harvesting cycles. Some microgreens such as pea sprouts and fenugreek can be harvested 3-4 times on average.
You can also re-grow microgreens.
To do this you have to take the roots and soil out of the pot and start with fresh soil and seeds instead.
Is Microgreen Regrowth Worth It?
Regrowing microgreens is not worth doing in terms of time and input. You can get microgreens from your pot a second time, but these will be late-sprouting seeds rather than vigorous regrowth plants.
Regrowing microgreens can be a huge waste of time and you may not get the result you expect. Regrown microgreens are of lesser quality and taste and take around the same length of time as growing from new.
This will reflect back to you both as a waste of time and as a financial expense. Instead of doing this, the roots should be removed from the soil and planting should be continued with new soil and seeds.
The time and effort you put into tending to regrown plants could be put to better use by replanting the microgreen entirely and creating a new plant community.
What Affects Microgreen Regrowth?
Although few harvests are made of microgreens, these plants are very difficult to regrow from the same seed. One of the main reasons for this is that the regrown seed does not have the necessary energy for the second and third growths.
Even if the soil is nutritious, the plant must perform photosynthesis in order to take in these minerals.
If you aim to regrow microgreens, you must leave a cluster of leaves on your microgreens. If you want to grow the microgreens again, you will have to do the previous harvests earlier.
This will give you the problem of dealing with baby greenery. If you want your microgreens to regrow, plant them in large pots.
In this way, the root structure will be of higher quality and will play an important role in the re-growth of microgreens.
Detailed Factors That the Regrowth of Microgreens
Photosynthesis and Cell Regeneration
If you leave the bottom leaf when cutting microgreens, you can facilitate photosynthesis in re-growth.
The plant can survive for a long time as the lowest leaves activate cell renewal, which ensures the continuation of growth.
Cut Healing And Defense
For the growth of microgreens, the cells must be constantly renewed. These plants, like other living things, have the capacity to heal themselves.
They have scar tissue that renews itself when they receive a wound. As a result of random cutting of microgreens, it is very difficult for those plants to renew themselves, so cutting must be done precisely.
Young plants are quite vulnerable to all kinds of infections. If they cannot renew themselves, they are at risk of dying. So timing when you cut is crucial.
It is very important to grow microgreens in sterile environments. It is very important that the environment is hygienic, especially in terms of protecting young plants from various infections.
How Long Do Microgreens Take To Grow?
Microgreens are very fast-growing micro plants. The growth period of these plants varies between 2-3 weeks on average.
Some microgreens, such as radishes and mustard, can grow more quickly. Some microgreens may take more than 1 month to grow.
The rapid growth of microgreens and the short time in harvesting cycles make this business very profitable. Many growers attempt this because of the fast harvesting trends.
What Happens If You Don’t Harvest Microgreens?
If you don’t harvest the microgreens, they will continue to grow and become large plants. The important point here is that they can find the necessary light and food for continuation into adulthood.
If the necessary conditions are met, they will become large mature plants. Microgreen seeds are used for the rapid growth of seedlings.
Therefore, if you do not harvest a microgreen community, the plant will become fully grown. If you grow microgreens to their full growth potential, you may not get the yield you want.
If microgreens do not have enough light, nutrients, and water, their growth will stop and after a while, they will die. In small pots, however, some microgreens may become dominant and deprive others of light and nutrients.
Therefore, seeds should be planted in a way that allowed each microgreen to grow well in every pot. When the excess seeds grow, they can cause each other to disappear and you will get a smaller harvest.
How Long Do Harvested Microgreens Last?
It is not possible for microgreens to last very long after being cut. The storage time of the microgreens you see in the markets is 1 week on average.
After this time, the microgreens begin to deteriorate. It takes a few days after the harvest for microgreens to take their place on supermarkets shelves and a few days more before they are purchased and eaten by the consumer.
But if you grow your own microgreens, they can stay intact for an average of 2 weeks after harvest.
How Long Can You Harvest Microgreens?
You can harvest microgreens for two weeks after growth. The shelf vertebrae of microgreens vary according to the type of microgreens.
Generally, microgreens in the markets should be delivered to the consumer within an average of 5-7 days.
If you are going to store microgreens at home, you can store them in the refrigerator. The maximum storage time in the refrigerator is 2 weeks. After this period, the microgreens begin to deteriorate.
Does it Pay off to Re-grow Microgreens?
Although regrowing microgreens may seem like a profitable business at first glance, you may not be able to get the quality plants you want because the seeds suffer from a lack of energy in the second growth.
This may mean that the effort you put in is wasted. This could result in you having to throw away these plants, which are not sufficient in terms of taste and consistency.
Even though you avoid the cost of new soil and seeds by reproducing microgreens, not getting the expected yield can incur more damage to you.
In addition, waiting for the seeds to sprout and mature again will waste your time. Re-growing microgreens is not a very profitable business when both time and effort are considered.
