How to Grow Alfalfa Microgreens in Soil?

Below are ten valuable instructions for Microgreen growers to keep in mind while growing Alfalfa Microgreens. Your home-grown microgreens will be fresh, delicious and, nutritious.

Step 1: Quantity of Soil in The Container

Firstly, choose an appropriate container, tray, or pot in which you intend to grow your Alfalfa Microgreens, then fill it with 3-4 inches of soil. This quantity of soil is enough for the roots of the microgreens as they are only small.

Step 2: Sowing Seeds

After filling the container with soil, you sow the seed. You just need to sprinkle the seeds on the surface of the soil, an uneven sprinkling works just fine. The soil just needs to catch and absorb the seed, and it will do the rest of the job itself.

Step 3: Covering the Seeds with Soil

A thin layer of soil is enough to cover the seed you have sprinkled on the soil in the container. A gentle stroke on the soil with the palm of your hand is good enough to settle the seeds in the soil.

Step 4: Watering the Soil

The soil needs good moisture but be careful to avoid excessive watering. The water should not overflow from the container. Sprinkling water is enough. It does not need heavy pouring pressure.

Step 5: Temperature

For the growth of microgreens to be successful they need to be kept at a moderate temperature. The temperature should be no less than room temperature until the process of germination starts. Once the germination process has begun, it is better to keep the microgreens in the sun where they can get the necessary amount of sunlight of 3-4 hours a day.

Step 6: Watering Microgreens After 3-4 Days

A regular sprinkling of water twice a day is required for the successful growth of the alfalfa microgreens. You will notice small leaves appearing on the surface of the soil, as well as tiny buds within 3 to 4 days.

Step 7: Be Patient

You will need to wait a week for your microgreens to grown. Once it has been a week you will see the container full of alfalfa microgreens plants. Now, you can either cut them right away or wait a few more days to let them grow taller.

Step 8: Avoid Jumping into Harvesting

Your hasty cutting of microgreens can destroy them. The delicate microgreens need to be harvested carefully. You can cut them with a pair of scissors or a sharp knife. Ensure you hold them at the roots when you cut them. Another way of harvesting your microgreens is to pluck them out with the roots intact carefully although this could damage them if not completed with care.

Step 9: Washing Microgreens

If you have reached this step your microgreen growing process is complete. Now, you can wash them with clean and cold water thoroughly. You should leave them out for them to dry. To store them you can wrap them up in some kitchen paper and preserve them in the fridge.

Step 10:  Alfalfa Microgreens are Ready to be Enjoyed

The whole process from sowing to harvesting microgreens is straightforward and pleasing. This makes the homegrown vegetables enjoyable, nutritious and healthy.

How to Grow Alfalfa Microgreens on Grow Mats?

Step 2: Filling the Grow Mat

Firstly, pour water over the grow mat and ensure it floats. It may take time to settle fully so be patient. The mat will become darker in colour when it gets saturated. You will not need to use any nutrients or rooting solutions.

Step 3: Spread the Seeds Proportionately on the Mat

This step does not have to be perfect but you need to aim to cover the mat in seeds. The closer together the seeds are, the better. Also, remember not to cover your seeds as it will prevent the sunlight from reaching in. The more exposed to sunlight the better it is.

Step 4: Watering the Seeds

Seeds need a lot of humidity to ensure their growth is successful—watering seeds by misting or spraying thoroughly once a day can fulfil this requirement. Grow mats have enough capacity to absorb water, and the air movement around the seeds promotes root growth as well as protecting them from diseases. Something that you should be careful about is that your grow mats do not float in water!

Step 5: Keep Observing the Microgreens Growing Process

You will need to observe the white fibres that might grow from the roots. Fibres growing from the seed itself is mould. But mould itself is not a problem if quick action is taken to resolve it.

To avoid the mould growing you will need to increase the air circulation, you can do this by moving the grow tray to an airy spot or using a fan. Remember the mat should be moist and it should not float in water.

Once the seeds have developed buds, they must have access to a lot of light. Move the tray to the sunny window or under a grow light. If you see tiny green tips appearing it will because the plants have not had enough light so they will grow tall, leggy, and floppy. If this happens your plants cannot be recovered.

Step 6: It’s Time to Harvest

After 8 to 15 days pass, you’ll notice that your plants have grown 2-3 leaves. This is the perfect time to harvest because you’ll get the best-flavoured microgreens. If you wait too long the taste of microgreens can become bitter.

Step 7: Storing Microgreens

However, microgreens can retain their delicious and crispy flavour for more than a week when they are stored with proper care. It is not hard to do. You just put them in the fridge and keep them dry.

What Pests/Diseases can Damage Microgreens and how to Stop Them?

Below are some essential points to have in mind to keep your microgreens healthy and save them from deadly diseases.


Botrytis is a type of fungus that causes a grey mould on the leaves which damages them. Cold and wet conditions are the factors behind this.

If you notice this happening, remove the affected spot immediately to save the remaining part of the plant. Do not water your microgreens at night. You can water on the side of the tray instead of sprinkling directly on the plant. You should ensure there is a good circulation of fresh air as it will prevent fungi from growing.

Root Rots

Pathogens are the causes of root deterioration on seeding. If you come to notice root deterioration, you must pull out the infected plant and make sure that the soil has got good drainage.


Damping-off is a common problem when starting. It looks healthful, but soon it droops and eventually dies. The fungus is the reason that grows vigorously in moisture. It means that the soil is excessively wet, therefore water less often.

Malnutrition Microgreens

If yellow foliage occurs, it means your microgreens have not had proper light. It can also come from an issue of overcrowding and not enough nutrients.

To solve this issue, you need to move the tray to a better place to get enough light and air. You can add a suitable amount of fertilizer as nutrients, and always stay alert about the pests. 


Sclerotinia is also known as white mould. It is a spider-like fungus that grows on the surface of the medium. It climbs on the plants and infects them causing them to die. To avoid this you need to decrease the amount of humidity around the plant. Good air circulation is required for the growth of the plant and avoid piling up seeds in the spreading process.


 Aphids remain hidden beneath the leaves and the disease spreads. They are different colors such as green, black, peach, and red. Aphids leave residues of the plants, which attracts ants.

The solution is that you must look for natural resistance for beetles and wasps that live on Aphids. Otherwise, you can spray strong insecticides.

Fear of Your Crops Being Eaten Up

If you grow your microgreens outdoors, you may face the problem of deer who might eat your crop. You will have to barricade your crops to protect them from wildlife entering the area in which you are growing your microgreens.

Beware of The Flea Beetles

Flea Beetles eat up foliage. Saving your crops from flea Beetles is possible through the rotation of the crops with other plants. Otherwise, you could use a floating row to protect the plants from damage.

Danger of Slugs

Slugs create holes in the foliage of plants by eating them. They usually do this at night and appear when the weather is wet.

Slugs can be picked off at night. You could attract them to traps by making holes in the ground and putting a cup or bowl in the holes and fill them with beer.

Rabbit Attacks

To some extent, Rabbits are also a threat to your crops. But their attack is less intense in comparison with Deer, who are extremely violent in their attack on the crops. The solution is to use repellents to try and save your crops or grow them indoors.
