Plus, these tiny greens boast big health benefits such as high levels of antioxidants and essential vitamins like Vitamin A, C and K.

But what’s the best way to make sure your microgreens are growing strong? Do they require fertilizer? Read on to find out if microgreens really need fertilizing!

Requirements For Growing Microgreens

Growing microgreens requires particular care to ensure successful harvests. The following are the requirements for growing microgreens:

Soil Requirements:

  • Microgreens need soil with a neutral pH and good drainage.
  • Compost or other organic matter can be added to improve the quality of the soil.

Light Requirements:

  • Most microgreens require 12-14 hours of light per day, depending on the variety grown.
  • If using artificial lighting, LED grow lights work best.

Water Requirements:

  • Keeping the soil slightly moist is important when growing microgreens.
  • Too much water will cause them to rot; too little water will prevent growth altogether.

Temperature Requirements:

  • Optimal temperatures for most varieties of microgreens range from 65°F (18°C) during the day to about 68–70°F (20–21°C) at night.

Once all these requirements are met, your microgreen crops should thrive! With proper attention, you’ll soon have fresh greens ready for harvesting and enjoying in salads, smoothies and more.

Natural Sources Of Fertilizer For Microgreens

When growing microgreens, natural fertilizer sources are an ideal choice for providing the necessary nutrients. Organic fertilizers provide a slow release of nitrogen and other essential elements to help promote healthy growth. Compost is one option that contains beneficial microbes that can promote soil health and fertility. Manure is also another great source of organic matter and can easily be added to the planting bed or potting mix. Vermicompost is made from worm castings and provides additional microbial activity while providing key nutrients like phosphorus, potassium, calcium, magnesium, iron, sulfur, boron and zinc.

Synthetic fertilizers may offer a quicker nutrient boost but they lack the long-term benefits of natural sources which build up soil structure over time. Synthetic fertilizers should only be used in combination with natural sources when needed; otherwise it’s best to stick with naturally derived alternatives for healthier plants. Transitioning seamlessly into the next section about synthetic fertilizers for microgreens will illustrate how different types of fertilizers work together to create optimal conditions for successful crop production.

Synthetic Fertilizers For Microgreens

Synthetic fertilizers are an easy and effective way to help microgreens reach their full potential. Many synthetic fertilizers contain a balanced mix of nitrogen, phosphorus, and potassium that can be used to give the plants just what they need when growing in containers or other small spaces. Synthetic fertilizers also last longer than organic options and provide more nutrients quicker.

When using synthetic fertilizer for microgreens, it is important to follow the instructions on the package carefully. Depending on the type of container you’re growing your greens in, you may want to adjust the amount of fertilizer accordingly. For example, if you’re growing microgreens in soil-less media like coco coir or rockwool cubes, then you should use less fertilizer since these types of mediums already have some nutrient content built into them. Additionally, pay attention to how often you apply fertilizer as over-fertilizing can lead to root burn and damage your plants.

Ultimately, finding the right balance between light, water and nutrition is key for successful microgreen production with any kind of fertilizer. With careful monitoring and attention to detail during each step of growth cycle – from germination through harvest – growers can ensure their microgreens will produce high yields without compromising quality. By following best practices for fertilizing microgreens, growers can create consistent harvests all year round while keeping their crop healthy throughout its lifecycle.

Best Practices For Fertilizing Microgreens

Fertilizing microgreens is like a dance; you need to find the right steps and timing so that your plants can flourish. To make sure your microgreens have all the nutrients they need, here are some best practices for fertilizing them properly.

Fertilizer Type Best Practices
Organic Add organic fertilizer every 2-4 weeks depending on plant type
Apply 1/2 teaspoon per square foot of soil surface area
Synthetic Apply synthetic fertilizer once a month or as directed by product label
Water in immediately after applying fertilizer for best absorption rate

When it comes to watering techniques, water when the top few inches of soil feel dry – don’t overwater! Additionally, adding mulch to keep moisture levels consistent will help promote healthy growth with minimal effort. Lastly, monitor your microgreens closely and be mindful of any changes in their appearance over time. With these tips, you should be able to create an environment where your microgreens thrive.


In conclusion, microgreens are a nutrient-packed superfood that can easily be grown in your home. Though they don’t require fertilizer to thrive, many gardeners choose to use it for optimal growth and nutrition of their plants. Natural sources like compost or aged manure provide essential nutrients while synthetic fertilizers offer quicker results. To achieve the best success when growing microgreens, follow modern horticultural practices such as diluting fertilizer solutions properly and monitoring soil pH levels regularly.
