This hardy microgreen thrives in various conditions, and with proper care, you'll be able to harvest your crop in as little as one to two weeks.
In this article, we'll delve into the process of growing sunflower microgreens from seed to harvest.
We'll guide you through each step, from preparing your growing tray to troubleshooting common issues.
You'll discover that with a few basic supplies and a little bit of patience, you can cultivate your own fresh, organic sunflower microgreens right in the comfort of your home.
Let's get started!
How To Grow Sunflower Microgreens
To successfully grow sunflower microgreens, it's crucial to understand their basic requirements.
Sunflower microgreens prefer a well-draining growing medium and plenty of sunlight. They do well in a room with ambient temperatures of about 70-80°F (21-27°C) and require frequent watering, but be careful not to overwater to prevent the growth of mold.
One important point to note about sunflower microgreens is that they require a bit more space compared to other microgreens. The seeds are larger and need to be spread out to prevent overcrowding, which can result in poor germination and growth.
Sunflower seeds need to be soaked before sowing to soften the hard shell and improve germination rates. Soaking for about 12 hours or overnight is usually sufficient.
To get started with your sunflower microgreens cultivation, you'll need to gather the following materials:
Sunflower Seeds: You should use black oil sunflower seeds, which are the most common for sprouting sunflower microgreens. They are packed with oil, leading to lusher and more nutritious microgreens.
Growing Trays: You'll need two growing trays — one with drainage holes for growing the microgreens and another without holes to serve as a water tray.
Growing Medium: A good organic potting soil, coco coir, or a specific microgreen growing medium works best. The growing medium should be well-draining but capable of retaining some moisture.
Spray Bottle: A spray bottle is necessary for evenly moistening the growing medium and watering the seeds after planting.
Light Source: Sunflower microgreens need plenty of light to grow. A south-facing window with lots of sunlight is great. However, if natural light isn't sufficient, you may need to use a grow light.
Other Tools: You'll need some additional tools like a trowel for spreading the soil, a watering can for hydrating the plants, and a pair of sharp scissors for harvesting.
Once you have gathered all your materials, you're ready to embark on the exciting journey of growing sunflower microgreens. Read on to learn about the step-by-step process.
Step 1. Soak The Seeds ---
Begin by placing the sunflower seeds in a glass or container, then fill it with water.
It's recommended to soak the seeds for a full 24 hours.
Once this period has elapsed, the seeds should be well hydrated and ready to be planted.
Step 2. Prepare The Growing Tray ---
The procedure here may vary depending on the type of growing tray you're using. Some are designed to be "self-watering", while others are standard 10 by 20-inch trays.
For this guide, we'll be using two 10 by 20-inch trays. One will serve as a water reservoir below the other tray, which will contain drainage holes, allowing water to reach the roots of the microgreens. This method helps prevent mold and simplifies the growing process.
Start by filling the tray without drainage holes with coco coir, then smooth out the surface. Mist it thoroughly with a spray bottle. If you lack a spray bottle, sprinkle water over the coco coir until it's uniformly moist.
Step 3. Add The Seeds ---
Next, scatter the seeds atop the moistened coco coir, distributing them evenly across the growing tray with your hands.
Even distribution is crucial to avoid overcrowding, which can lead to various problems. Be careful not to oversow or undersow!
Afterwards, place a 10 by 20-inch tray on top of the seeds, adding weight with a small, heavy object, such as a piece of wood.
Sunflower seeds require a humid, dark environment to germinate successfully. Position your tray in an area where it won't become excessively hot or cold.
The ideal temperature range is 65 to 75 degrees Fahrenheit. This initiates the germination process. Continue to mist the seeds approximately 15 times every 10-12 hours.
Step 4. Uncover and Give Light ---
After another 24 hours, remove the tray from the seeds. You should now see the roots extending into the coco coir.
At this stage, your sunflower microgreens need at least 12 hours of light daily. I highly recommend using LED grow lights, although direct sunlight and fluorescent lights are also suitable.
If your microgreens start leaning towards the light source, rotate the tray periodically. Don't worry if you notice some uneven growth—it's a common occurrence.
Step 5. Check Daily ---
Maintaining the right water balance is crucial from this point until harvest. Now is the time to utilize the bottom tray. Rather than using the spray bottle, fill the bottom tray with water—be cautious not to overfill it.
While it's still possible to water from the top, make sure to avoid wetting the leaves as this could promote mold growth.
Troubleshooting Common Sunflower Microgreens Growing Challenges
Despite your best efforts, you might encounter some difficulties while growing sunflower microgreens. Don't worry—many of these challenges are common and can be easily addressed.
If your sunflower seeds are not germinating well, the issue might lie in the quality of the seeds, incorrect soaking times, or improper growing conditions.
Ensure that your seeds are fresh and sourced from a reputable supplier.
Sunflower seeds typically need to be soaked for 12-24 hours before planting. Also, remember that they thrive in temperatures between 65-75°F.
Mold is a common problem in microgreen cultivation, often due to overwatering, poor air circulation, or high humidity.
If mold appears, it may be necessary to reduce watering, increase air circulation with a fan, or lower humidity levels in your growing environment.
Leggy or Pale Microgreens
If your sunflower microgreens appear leggy (elongated and thin) or pale, they might not be receiving enough light.
Consider positioning them closer to the light source or increasing the duration of light exposure.
Damping off is a fungal disease that causes seedlings to collapse and die. It's usually caused by overwatering or a contaminated growing medium.
To prevent this, ensure your growing medium is sterile, and do not overwater your plants.
If your sunflower microgreens are growing slower than expected, the cause might be inadequate lighting, low temperature, or nutrient deficiency.
Check your growing conditions and make necessary adjustments.
Remember, growing microgreens is a learning process. It's okay to make mistakes.
By troubleshooting these common problems, you'll gain a better understanding of your plants' needs and how to successfully cultivate them.
Enjoy the process and the tasty, nutrient-dense greens it yields!
How To Harvest Sunflower Microgreens
Sunflower microgreens typically reach their prime for harvesting between 7 to 12 days post-sprouting.
To maintain their freshness and prevent wilting, it's advisable to move your trays to a cool, shaded location before harvesting.
Harvesting in cooler temperatures - either late evening or early morning - helps keep the greens crisp and fresh.
Using a pair of scissors or a knife, carefully snip the top three inches of the shoots, ensuring not to damage the growing medium beneath.
Congratulations, you've successfully harvested your sunflower microgreens!
Rinsing and Drying Sunflower Microgreens
Next, thoroughly rinse the harvested microgreens under cold running water using a colander.
Spread the greens on a clean towel or paper towels and allow them to air dry completely.
To expedite the drying process, you may use a fan on a low setting.
Storing Sunflower Microgreens
Although sunflower microgreens are most flavorful when consumed immediately after harvesting and drying, they can be stored in a refrigerator for several days if necessary.
Place the microgreens loosely in a bowl or container and refrigerate. Remember, only completely dry microgreens should be refrigerated to avoid spoilage.
What Sunflower Microgreens Can Be Used For
Sunflower microgreens can add a burst of flavor and nutrition to various dishes, including salads, soups, sandwiches, and even baked goods.
They can also be juiced and added to wheatgrass shots or smoothies for an added nutritional punch.
