What You'll Learn
Gather Materials
Gather the necessary materials–seeds, medium, water, and light–to start growing your watercress microgreens. Choosing the right seeds is a key step in growing healthy microgreens. Look for organic heirloom varieties of watercress seeds that are specifically labeled for microgreen production.
You’ll need enough to fill whatever size container you’ve chosen to grow your crop in. The medium should be a lightweight soil mixture specifically designed for seed germination—you may also choose a certified organic mix if preferred. Soil preparation is an important factor when it comes to successful microgreen harvests; the soil should be moist but not soggy before planting your seeds and watered regularly afterwards.
Lastly, ample lighting (natural or artificial) is essential for optimal growth as watercress requires 14-18 hours of light per day. If you don’t have access to natural sunlight, you can use fluorescent or LED lights at least 6 inches above the plants and adjust them accordingly.
Now that you have all the materials needed to begin growing your own watercress microgreens, it’s time to get started!
Sow Seeds
Start by scattering your seeds onto the nutrient-rich soil to begin the process of growing watercress microgreens. Choose a soil that’s light and airy, such as a compost-based growing medium. The quality of your seed is also important; buy certified organic or untreated watercress seeds for best results.
Once you’ve scattered the seeds on top of the soil, cover them lightly with more medium and press down gently but firmly. Next, make sure to keep the soil evenly moist at all times while your watercress microgreens are germinating—about 7 days in total—by misting it regularly with a spray bottle. Make sure not to submerge your tray in water, as this can lead to fungal growth and rot.
In order for these tiny greens to grow strong and healthy, they need plenty of sunlight or artificial lighting; depending on where you are located, this can range from 8-12 hours per day. It’s important to remember that overcrowding will cause poor air flow between plants which can lead to wilting and disease—so be mindful when sowing your seeds!
Keep an eye out for any weeds that may sprout up during this time too. Remove them promptly so they don’t compete with your watercress plants for nutrients and sunlight. Harvest time should occur about 2 weeks after initial planting.
Check that the leaves are tall enough (at least 1 inch) before clipping them off near their base using scissors or kitchen shears – then enjoy!
Keep Seeds Moist
Keep your seeds hydrated by misting them regularly with a spray bottle, so they can thrive and develop into healthy watercress microgreens. To maintain the right amount of moisture in the soil, you can use mulching methods such as covering the soil with organic matter like wood chips or straw. This will help reduce evaporation from the soil.
It’s important to monitor how much moisture is in your growing medium; too much or too little can have a negative effect on your watercress seedlings. You can check the moisture content using a soil thermometer or hygrometer, which measure both temperature and humidity levels. These tools will tell you when it’s time to mist again.
You should also keep an eye on air circulation around your seedlings. If there isn’t enough airflow, it could cause mold growth or even root rot due to high humidity levels. Make sure to space out plants and provide adequate ventilation between them for maximum air flow. Additionally, place trays filled with pebbles under potted plants to increase air circulation while keeping soils moist for longer periods of time.
When it comes to watering your watercress microgreens, avoid overwatering at all costs! Too much water can suffocate roots and lead to soggy stems that are more prone to disease and pests. Instead of pouring large amounts of water onto your plants directly, try using a watering wand or other device that helps distribute water evenly throughout the container without over-saturating any area specifically.
The key is finding just the right balance between not enough moisture and too much. Your goal should be achieving a consistently moist growing environment for optimal health and growth results! Monitor this closely during germination stage until seedlings are established; then periodically check for adequate moisture levels once they reach maturity so you can enjoy delicious watercress microgreens all season long!
Provide Ample Light
Provide your watercress microgreens with bright light and plenty of sunshine to ensure they thrive and reach their full potential. One of the most important aspects of successfully growing watercress microgreens is making sure they get enough light – ideally, natural sunlight from outdoors. If you’re unable to place your plants outside, then you should use a grow light setup or fluorescent bulbs that mimic natural lighting. Aim for 12-14 hours of bright light per day, ensuring that plants are gathering sunlight throughout the day so they can photosynthesize and produce all the necessary energy for healthy growth.
If you have limited space indoors, it’s best to hang your grow lights as close as possible to the plants without burning them – about 1 inch away is ideal. Make sure you adjust the height every few weeks as your plants grow in order to keep them at an even distance from the lights. You may also need to rotate or move trays around if some areas receive more direct sunlight than others. All these steps will help your watercress microgreens get enough natural lighting for optimal growth and development.
It’s important not to forget about providing adequate darkness as well – just like humans require a certain amount of sleep each night, so do plants! Aim for 8-10 hours of pure darkness during which no artificial or natural light source is present in order to give them time to rest and regenerate before another round of photosynthesis begins again in the morning.
By following these tips on providing ample light for your watercress microgreens, you can guarantee that they’ll be able to take full advantage of this essential resource while avoiding any stunted growth due to inadequate lighting conditions. With patience and dedication, you’ll soon be rewarded with lush crops bursting with flavor!
Thin Out Seedlings
Once your watercress microgreens have sprouted, you’ll need to thin them out to ensure they have enough room and resources to grow. The best way to do this is by hand, using tweezers or scissors.
Pull weeds as soon as they appear to control the growth of unwanted plants and maintain soil quality.
Thin out seedlings so that there are two inches between each one. This will give them plenty of room for their roots to spread and absorb nutrients from the soil. It will also help prevent overcrowding, which could cause some seedlings to not get enough sunlight or water due to competition from other plants nearby.
When thinning out your seedlings, take care not to damage or disturb the roots of nearby plants. Try snipping off any excess shoots at their base instead of pulling them up by their stems.
If you’re going with a scissors approach, make sure you only remove a few leaves per cut so your remaining greens can still receive adequate light and nutrition from the sun and soil nutrients respectively.
By taking these precautions when thinning out your watercress microgreens, you can ensure they get all the right conditions needed for healthy growth and development over time.
Be mindful of how much fertilizer you use when growing watercress microgreens. Too much can lead to an excessive build-up of salts in the soil, which can be damaging for young root systems. Instead, opt for organic fertilizers that provide balanced levels of nitrogen, phosphorus, potassium, and other trace elements needed for optimal plant health without compromising on weed control or soil quality over time.
Finally, remember that regular maintenance is key when it comes to keeping your watercress microgreens healthy and vibrant. This includes thinning out new seedlings every few weeks, as well as monitoring moisture levels to avoid over-watering or underwatering them at any given time. With proper care and attention paid towards these details throughout its life cycle, your crop should thrive beautifully!
Harvest Watercress Microgreens
Harvesting your watercress microgreens is easy! Cut them above the soil level with a pair of scissors or knife.
Then rinse them in cold water for a few minutes and you’re done! You’ll be rewarded with a delicious, nutritious snack that’s packed full of flavor.
Cut above soil level
When you’re ready to harvest your watercress microgreens, cut them above soil level for the best results – it’s a piece of cake!
Proper soil preparation is necessary to ensure that your microgreens get the right balance of nutrients they need. Make sure the soil is moist and rich in organic matter before sowing your watercress seeds. You can also add some additional nutrient sources like compost, aged manure or fish emulsion for an extra boost.
Once you’ve cut the microgreens above soil level, rinse them gently with fresh water before serving or storing. This will remove any dirt particles that may have been clinging to them during harvest.

Rinse with cold water
Gently rinse your freshly-harvested microgreens with cold water to remove any dirt particles that may have been clinging to them during harvest. Using cold water is important; warm water can cause the delicate leaves and stems of the microgreen to wilt, reducing their nutritional value. Cold water also helps preserve the soil nutrition that has been absorbed by the plant during its growth period.
Make sure to keep a steady temperature when rinsing – too hot or too cold can be damaging. After rinsing, pat dry with a paper towel and enjoy your fresh and nutritious microgreens!
