Growing Microgreens Start to Finish: A Comprehensive Guide

HomeGrowingGrowing Microgreens Start to Finish: A Comprehensive Guide

Growing microgreens from start to finish involves several steps. Firstly, seed selection is crucial, as different varieties have different growth requirements. Next, the seeds are planted in a suitable growing medium and kept moist for germination. After germination, the microgreens are provided with light and proper care to promote healthy growth. Finally, the microgreens are harvested when they reach their desired size and flavor.

Seed Selection

You can have the freshest microgreens around by carefully selecting your seeds! Knowing the different seed types and planting mediums is essential to a successful microgreen-growing experience.

Whether you’re growing from packets of seeds or buying them in bulk, it’s important to know what type of seed you are working with so that you can provide the optimal environment for germination and growth.

The most common seed types used for growing microgreens include vegetable, herb, and flower varieties such as arugula, radish, mustard greens, basil, cilantro, kale, chard, beets, carrots and sunflowers.

While some packets may specify which type of soil should be used for each variety of seed—whether it’s potting mix or organic compost—it’s always best to start with a high-quality soil mix designed specifically for microgreens. This ensures that your plants will have adequate drainage and nutrients needed to thrive during their short life cycle.

For easy cleanup after harvesting your greens, consider investing in spray bottles or small trays with holes drilled into the bottom so that excess water can easily drain away from the roots of your plants.

Once you’ve found a good spot in your home to begin sowing your seeds (ideally somewhere bright but out of direct sunlight), simply scatter them over the surface of the soil and lightly press down until they make contact with the dirt below. Once they are all planted, it’s time to give them a light misting of water before covering them up with more soil if desired.

After about one week, you should begin seeing signs of life coming from beneath the soil! As long as your plants get enough light (but not too much) and stay moist but not waterlogged during their growth period, then they should be ready for harvest within 2–3 weeks depending on what variety you chose.

With these tips in mind, you can become an expert at growing delicious microgreens in no time at all!


When it comes to planting microgreens, you’ll need to start by preparing the soil. Ensure that your potting mix is light and well-draining.

Once your soil is ready, place your seeds in the soil. Make sure that they are evenly spread out and not too deep or shallow.

Finally, keep the moisture levels consistent throughout the growing process–you don’t want them too dry or too wet!

Soil Preparation

Prior to planting, you’ll need to prepare the soil by adding a nutrient-rich compost, ensuring it’s lightly damp and aerated for optimal germination.

The type of container you choose will also play an important role in the success of your microgreens. In order to provide optimal nutrition and air flow, it’s best to use a shallow container with drainage holes – such as plastic trays or planter boxes – that are at least two inches deep.

When selecting compost for your microgreen garden, look for one that’s organic and contains plenty of nitrogen and phosphorus essential for plant growth. Make sure to break up any clumps before mixing with your existing soil so that the compost can be evenly distributed throughout the potting medium.

Once combined, lightly water the mix until damp but not soggy in order to ensure proper aeration when planting your seeds.

Seed Placement

Sprinkle your seeds evenly across the damp soil, ensuring they’re spaced out to allow for optimal germination. It’s important to ensure that the seeds are placed in a way that allows for even light exposure and temperature control during their growth process.

If you’re growing multiple varieties of microgreens, it’s best practice to separate them into different sections of the planting tray. Each variety will have its own light and temperature needs. Consider placing taller varieties along the edges of the tray and shorter varieties toward the center, so all the plants receive direct sunlight at some point throughout their growth period.

Be careful not to overcrowd your seeds. Instead, place them with at least an inch or two between each one so they have plenty of room to grow.

Moisture Requirements

Maintaining optimal moisture levels is key to successful microgreen growth, so keep your soil damp like a sponge in order to nourish the tiny sprouts and give them a chance to thrive.

To do this, there are several different watering techniques that can be used. First, it’s important to water lightly but often enough to keep the soil moist but not soaked. Second, you should avoid over-watering as this can cause mold or mildew growth on the plants. Third, avoid wetting the leaves of your microgreens as this may cause disease or pest problems. Lastly, consider investing in an automated irrigation system if possible as this will help ensure proper hydration without over-watering or under-watering your plants.

In addition to moisture needs, light also plays an important role in the growth of microgreens. Generally speaking, most types of microgreens need 8-10 hours of direct sunlight each day for best results. If outdoor conditions make it difficult to provide adequate sunlight all day long, then supplementing with grow lights may be necessary in order to achieve consistent growth and strong yields from your crop.

Additionally, you want to ensure that whatever light source you choose has full spectrum coverage for maximum photosynthesis potential and plant health.


Once your seeds are planted, germination is the process of them sprouting and growing into microgreens. The key to successful germination lies in providing the right environment for your seeds to thrive.

This includes soil nutrition, light exposure, and moisture levels. It’s important to make sure that the soil has adequate levels of nutrients like nitrogen, phosphorus, and potassium so that your microgreens can grow healthy and strong from the start.

Furthermore, you need to ensure that your plants get enough sunlight or artificial lighting during their growth period as it helps stimulate photosynthesis in plants which aids in their development. Lastly, proper moisture should be maintained throughout this stage as too much or too little water can both lead to stunted growth or death of your microgreens.

To achieve a good germination rate with your microgreens, it’s important to pay attention to the temperature and humidity requirements for specific varieties. For example, some varieties may require temperatures between 65-80°F while others may prefer cooler temperatures closer to 50-70°F depending on the type of seed being used.

The same goes for humidity; some types may prefer higher humidity levels while others do better with lower ones so knowing what type of seed you’re working with will help you determine what range you need to maintain during this stage of growth.

Additionally, providing adequate air circulation around your plants is essential as stagnant air can result in mold or fungus developing on them which could damage or even kill them off completely if left unchecked. You also want to avoid overcrowding when planting multiple types of microgreens together as they will compete for resources like light exposure and nutrient availability which could lead to slower growth overall.

Finally, once all these conditions have been met during germination, it’s time to move onto the next step: growth! Here you’ll be focusing on ensuring that all environmental factors remain consistent while actively monitoring plant health over time so any issues can be addressed quickly before they become major problems down the line.


To help your microgreens reach their full potential, you’ll need to focus on nurturing them through the growth stage. During this stage, your microgreens will need plenty of light and nutrients in order to thrive. To ensure that they get the best possible care:

  1. Make sure the area where you’re growing your microgreens is adequately lit. They should be receiving direct or indirect sunlight for at least 6 hours a day.
  2. Feed your plants with nutrient-rich soil and water regularly. You can also use a liquid fertilizer mix to supplement their diet once a week if desired.
  3. Monitor the temperature of your plants’ environment and adjust as needed. Most microgreens prefer temperatures between 60°F – 70°F (15°C – 21°C).

In addition, it’s important to thin out any overcrowded seedlings when they start to sprout up. Each plant should receive enough space to grow properly, as well as adequate air circulation throughout its leaves and stems. With these key factors taken into consideration, you can ensure that your microgreens have an optimal chance of thriving through the growth stage!


When it comes time for harvesting, you’ll want to ensure that your microgreens are ready to be cut and eaten. Knowing when to harvest is key for getting the most flavor out of your crop, so pay close attention to the development of your plants.

Generally speaking, you should wait until at least two sets of true leaves have grown before cutting them near the base. It’s also important to note that some species may require a longer wait time than others; if in doubt, look up what specific variety you’re growing and follow its guidelines.

Once it’s time to start harvesting, having a few basic cleaning tools on hand can make the process easier and less messy. Start by preparing your work area with newspaper or plastic sheeting, which can help protect surfaces from any residual dirt or soil that might come off during the cutting process.

You will also need something like scissors or garden shears for trimming the greens as close as possible to their root systems without damaging them too much. Lastly, gather a bowl or container for collecting the harvested greens; this will make them easier to transport and clean later on.

It’s important not to leave freshly cut microgreens lying around too long after they’ve been harvested; their taste and texture can change quickly once exposed to air and light. To avoid this problem, try washing them immediately after they’ve been cut using cold water and gentle soap (if necessary).

This will help keep them fresh while removing any additional dirt or debris that might have collected on their surface during harvesting. Finally, spread out the washed greens onto paper towels or cloth napkins so they can dry before storage – just make sure they don’t stay wet for too long!

Once they’re completely dry, put your microgreens into an airtight container such as a mason jar or ziplock bag before storing in either the refrigerator or freezer (depending on how soon you plan on eating them). Doing this will help preserve their flavor and texture so that they remain fresh-tasting even after being frozen!

Storage and Preservation

Now that your microgreens have been harvested, you’ll want to store and preserve them properly so their flavor and texture lasts as long as possible! The best way to do this is by selecting the right packaging method.

For most microgreens, pre-packaged plastic bags or airtight containers are a good option. They will keep your greens fresh for longer and help prevent spoilage due to moisture or oxygen exposure. It’s also important to make sure that any containers used are clean and free of debris or dirt before storing the microgreens.

When it comes to shelf life, the type of green you grow will determine how long they can last in storage. Most varieties will remain fresh for up to two weeks when stored in an airtight container at a temperature between 32°F (0°C) and 41°F (5°C). If you need them to last longer than two weeks, freezing is a great option – just make sure you don’t put them directly into the freezer without some sort of protection from freezer burn!

It’s also important to consider how much moisture is present in your storage area – too much moisture can create condensation which could lead to mold formation on the greens, so make sure there’s enough ventilation in whatever space you’re using for storage. Additionally, if storing multiple types of microgreens together, it’s important to ensure that none of them are touching each other since contact between different varieties may cause cross contamination.

Finally, remember that light levels can also affect shelf life – try not to expose your stored microgreens to direct sunlight or bright lights as this could accelerate spoilage. Be sure to follow these tips when storing and preserving your freshly harvested microgreens so they stay crisp and flavorful for longer!
