Growing microgreens in jars is an innovative and convenient method for those with limited gardening space or who want to grow their own food year-round. Affectionately known as “vegetable confetti,” microgreens are tiny, edible greens grown from the seeds of vegetables and herbs. They usually range in size from one to two inches long, including the stem and leaves.
Families with children, city-dwellers living in apartments, or those who do not have the luxury of a backyard garden can turn to jar-growing microgreens for a practical solution. As a remarkable source of nutrients, microgreens yield a flavorful and colorful addition to any meal.
In this article, we will comprehensively detail the steps on how to grow microgreens in jars.
Selecting Your Microgreens
Before anything else, it’s crucial to decide what type of microgreens you wish to grow. Some popular types include radish, spinach, kale, chard, beet, and herbs such as basil or cilantro. Your choice may rely on factors like personal preference, the growth speed, and the easy maintenance of certain microgreens.
Choosing Your Jars
When selecting your jars, opt for wide-mouth ones for easy planting and harvesting. Ensure they are transparent to allow ample light for photosynthesis, thereby supporting your microgreens’ growth.
Prepping Your Jars
To start off, thoroughly clean your jars with warm water and soap, ensuring that there are no residues left. This is vital to prevent potential bacteria or fungus that could harm the delicate seedlings.
Soil and Planting
Fill your jars up to two-thirds with potting mix, leaving room for the dividing layer and the seeds. The type of soil matters a lot, so choose well-draining soil, rich in organic matter. Evenly distribute seeds at the surface, basically covering the whole soil area.
The Separating Layer
Here, you’d need a layer of vermiculite or perlite. This separating layer aids in maintaining the appropriate moisture level for your seeds to germinate. It also guards against molds or microorganisms that could interfere with your seedlings’ growth. Pour it atop the seeds until barely visible, but not completely covered.
Watering and Germination
Water your seeds lightly, ideally with a spray bottle for a gentle effect. It’s crucial to keep the soil consistently moist but never oversaturated. Place the jars in a warm, well-lit area but avoid direct sunlight which can dry out the soil quickly. Seeds germination can take anywhere between three days to a week.
The Growth Phase
Once your seeds have germinated, they will need about 12-16 hours of light daily. However, direct sunlight can be too intense, so opt for a north-facing window or simply use grow lights. Keep watering your microgreens lightly but consistently to ensure the soil doesn’t dry out.
Harvesting Microgreens
You can start harvesting your jar-grown microgreens when they reach around two inches in height, usually between 7-14 days. Harvest by snipping the stems just above the soil level with clean scissors, taking care not to pull them out.
Care and Maintenance
Post-harvest, your microgreen jars may have another go. Moisten the soil again and spread a new batch of seeds. Some microgreens can rebloom, but in most cases, it’s best to start fresh for another harvest.
Further Tips
For a continuous supply of microgreens, stagger your planting. Start a new jar every few days. This way, there will always be a jar ready for harvest. Also, ensure your jars are clean always to prevent any disease risk.
Growing microgreens is an excellent step towards sustainable living. The jar method makes it simple for anyone to cultivate their own nutritious greens, regardless of the space.
