The selection of appropriate containers is a crucial aspect of successfully growing microgreens with organic fertilizer. Well-draining containers facilitate proper water management and aeration, which are essential for the healthy development of microgreens.

Organic fertilizers, such as compost or manure, provide a nutrient-rich environment for microgreens. However, these fertilizers can retain moisture, making well-draining containers necessary to prevent waterlogging. Excess water can lead to root rot and other issues that can hinder microgreen growth.

Furthermore, microgreens have relatively shallow root systems, so it is important to choose containers that are not too deep. Shallow containers allow for proper root development and prevent the roots from becoming waterlogged.

The size of the container should also be considered. Microgreens require enough space to spread their roots and access nutrients. Overcrowding can lead to stunted growth and competition for resources.

By selecting well-draining containers that are large enough to accommodate the root system of the microgreens, growers can create an optimal environment for microgreen growth when using organic fertilizer.


Water is essential for microgreen growth and development, but it is important to strike a balance between providing enough water and avoiding overwatering. Overwatering can lead to waterlogged soil, which can promote root rot and other diseases. It can also leach nutrients from the soil, making them unavailable to the microgreens.

When watering microgreens, it is best to use a gentle stream of water and avoid directly spraying the plants. This will help to prevent damage to the delicate seedlings. It is also important to water the soil evenly, avoiding pockets of dry or waterlogged soil.

The frequency of watering will vary depending on the climate and the type of microgreens being grown. As a general rule, microgreens should be watered daily, or more often in hot, dry climates. It is important to check the soil moisture before watering, and only water when the top inch of soil is dry to the touch.

By following these tips, you can ensure that your microgreens receive the water they need to thrive without overwatering.


Light is essential for photosynthesis, the process by which plants convert sunlight into energy. Microgreens require plenty of light to grow and develop properly. Without adequate light, microgreens will become leggy and weak, and their leaves will be pale and underdeveloped.

The best source of light for microgreens is natural sunlight. However, if you are growing microgreens indoors, you will need to provide them with artificial light. Artificial lights can be placed on a timer to ensure that the microgreens receive the light they need.

The amount of light that microgreens need will vary depending on the variety of microgreens being grown. Some microgreens, such as broccoli and radish, require more light than others, such as peas and sunflowers.

By providing your microgreens with plenty of light, you will help them to grow healthy and strong. This will result in a higher yield of microgreens that are full of nutrients and flavor.

In addition to providing light for photosynthesis, light also helps to regulate the growth of microgreens. Light signals to the plant that it is time to start producing leaves and stems. Without light, microgreens will not be able to grow properly.


Harvesting microgreens at the proper time is crucial in the process of growing microgreens with organic fertilizer. Harvesting too early or too late can affect the quality and nutritional value of the microgreens.

When microgreens are harvested at the desired height, typically 1-2 inches, they are at their peak of nutrient content and flavor. Harvesting at the correct height ensures that the microgreens have developed their full potential and have not become overgrown or bitter.

To harvest microgreens, use a sharp knife or scissors to cut the stems just above the soil line. Be careful not to damage the roots, as this can prevent the microgreens from regrowing. After harvesting, rinse the microgreens thoroughly in cold water and pat them dry.

Microgreens can be harvested multiple times, as they will continue to regrow after being cut. By harvesting at the desired height and following proper harvesting techniques, you can enjoy fresh, nutrient-rich microgreens all year round.


Storing microgreens properly is an essential aspect of growing microgreens with organic fertilizer. Understanding the significance of storage techniques helps preserve the freshness, nutritional value, and quality of the microgreens for optimal consumption and utilization.

  • Preservation of Nutrients: Refrigeration slows down the enzymatic reactions that degrade nutrients, thereby preserving the vitamin, mineral, and antioxidant content of the microgreens.
  • Inhibition of Microbial Growth: Cold temperatures inhibit the growth of bacteria and mold, preventing spoilage and extending the shelf life of the microgreens.
  • Maintenance of Freshness: Refrigeration helps maintain the crisp texture and vibrant color of the microgreens, ensuring they remain visually appealing and palatable.
  • Convenience and Accessibility: Storing microgreens in the refrigerator allows for convenient access and easy incorporation into meals and recipes, promoting regular consumption of these nutrient-rich greens.

Proper storage techniques, such as refrigeration, complement the efforts put into growing microgreens with organic fertilizer. By preserving the freshness and nutritional integrity of the microgreens, storage practices contribute to the overall success and sustainability of microgreen cultivation.
