What Happens If You Don’t Harvest Microgreens? (Solved & Explained!)

If you don’t harvest the microgreens, they will stop growing and die after a while. Since microgreens are different from other large mature plants, they must be harvested after they reach a certain maturity. 

If they are not harvested, they will grow to full size then die.

Can Microgreens Grow to Full Size?

The effect of microgreens on human health and their nutritional benefits are better understood by researchers, and this has led to an increase in interest in microgreens. 

It is true that microgreens grow to full size, but microgreens do not reach large mature plant sizes. They will die shortly after becoming larger and will not grow back again.

Do Microgreens Keep Growing?

Like every living thing, microgreens have a sprouting and growing period. After the microgreens are left in a dark environment from seed to sprouting, they are taken to the sunlight for the growth phase. 

After microgreens reach their required size, their growth will end and they will begin to decline. After planting the microgreens, the seeds will compete with each other for nutrients and this competition will continue during the growth phase. 

This will reflect as stress on the microgreens and they will not have enough energy to grow further. 

Another reason microgreens may struggle to grow is if you don’t prepare enough ground soil for them to grow. 

The seeds are very competitive, and if there is not enough soil to go around they will take nutrients from each other and essentially cancel each other out.


If the microgreens are cut, the roots remain. Likewise, after harvesting a microgreen, it will be very difficult to grow a new plant from the same seed.

Even if you get a new plant, that plant will not fully mature as the used seed has been exhausted from the previous growth and does not have enough energy to complete the new growth cycle.

As a result, microgreens will not continue to grow, after they reach a certain maturity, their energy will run out and they will die.

What if You Give the Microgreens More Soil and Nutrients?

Giving your microgreens extra soil and nutrients won’t change a thing, either for them to grow again after harvesting or to continue growing. 

Because the seeds will not find the energy to achieve continuity again, they will become larger plants. 

They will be under stress as they compete with other plants for nutrients during the growth phase. This stress will not allow them to grow any further. 

If you are thinking of growing your microgreens as large mature plants, you will need to give them enough space and nutrition and grow them in a comfortable environment, which will help the microgreens grow into mature large plants. 

Only in this way can you obtain mature large plants. Microgreens will not continue to grow no matter how good the soil is, no matter how much supplemental food you give them, and they will die after they reach a certain maturity.

How Big Do Microgreens Get?

Microgreens can sometimes be confused with sprouted seeds. Due to this confusion, microgreens that are not yet ripe are harvested too early.

When the microgreens mature, they should be around 2-3 inches in size. Many producers think that the sprouts are mature plants before they reach this size and harvest them early. This will result in immature raw plants that have less nutritional value.

Do You Have to Harvest Microgreens?

Microgreens should be harvested when they reach a certain size. This is because microgreens stop growing after they reach maturity, depending on their space and soil availability.

After the microgreens mature, they stop growing and lose their energy over time. The reason for their death is that the plants in the soil compete for nutrients and get stressed. 

In addition, the inability to maintain the energy in the seeds is another reason why these plants stop growing.

Do Microgreens Keep Growing Back?

Microgreens cannot regrow, or they may regrow once but die very shortly after sprouting. After harvesting, the seeds will likely die because they cannot maintain the energy to grow again. 

But with a wider tray and additional nutrients, you can ensure that the seeds grow more easily. 

Although microgreens are easy plants to grow, you cannot harvest them repeatedly like some plants. 

These plants have very short harvest times and will die or become much worse in quality after the first harvest. Although some microgreens tend to grow back, they will not fully mature.

Can Microgreens Go Bad?

Microgreens are perishable like other plants. They can break down if they are not properly cared for and given enough attention. 

You can easily tell that these plants have been spoiled by their changing colors and bad smells. The stems of plants become softer and tend to break.

You can easily distinguish a spoiled microgreen from a fresh microgreen.

Can You Grow Microgreens Without Soil?

Microgreens are one of the wonderful plant species that you can grow without soil even on windowsills. 

These plants are often confused with sprouts. You can easily grow microgreens, which are the upper part of the soil.

You can grow microgreens successfully in a tray with a nutrient solution, with no soil required.

Can Microgreens Grow to Full Size?

Microgreens do not grow to full size. After a certain growth period, their growth comes to an end and they come to fruition. 

Some growers may aim to produce older plants from microgreens using larger trays and fertile soils. 

This is possible, but not every microgreen can become a mature large plant. When the necessary environment for microgreens is prepared, they can grow. 

What you need to do for this is to provide plenty of fertile soil, sufficient light, and extra nutrients. In this way, the plants will be protected from stress and become more productive.

Are Microgreens Just Baby Plants?

Microgreens are 2-3 week old young plants. These plants are just like baby plants, but baby plants are slightly older than microgreens. 

In general, all microgreens are baby greens. The fact that microgreens are minimal in size and have short harvesting cycles puts them in the category of baby greens.
