HomeGrowingHow to Grow Arugula Microgreens? Cultivation Instructions

Arugula microgreens thrive in well-draining soil with consistent moisture and adequate light. Start by evenly sowing the seeds onto the growing medium, lightly covering them with a thin layer of soil, and misting with water. Maintain moisture throughout the growing process, ensuring the soil doesn’t dry out. Adequate light, either from natural sunlight or grow lights, is crucial for healthy arugula microgreen growth.

Select the Right Soil

When it comes to growing arugula microgreens, you’ll want to select soil that is well-draining and has a balanced moisture level – not too wet, not too dry. If the soil is too wet or not draining properly, the roots of the microgreen will be deprived of oxygen and can become susceptible to diseases.

Additionally, make sure the soil has enough nutrition for your arugula microgreens; a good source of nutrients includes compost or aged manure. The pH level should also be considered when selecting your soil as the optimal pH range for growing arugula microgreens is 6-7. If your soil falls outside this range, consider adding lime or sulfur to help balance out the pH.

To ensure your arugula microgreens have all they need to grow healthily and successfully, test the drainage rate and nutrient availability in your chosen soil prior to planting them. Drainage rate testing can be done by filling up a container with about four inches of water and allowing it to sit for an hour before measuring how much water has drained into a bucket below it after an hour’s time; if more than 1 inch remains in the container then additional drainage may be needed in order for successful growth of your arugula microgreens.

For nutrient availability testing, you can purchase kits from gardening stores that provide detailed information on nutrient levels present in your soil so you know what kind of amendments (if any) are necessary prior to planting day.

Once you’ve selected appropriate soil for growing arugula microgreens, make sure it is evenly moist so as not to drown any root systems while still supplying adequate oxygenation levels – watering lightly several times per week should do just fine! Finally, remember that light plays an important role during germination; without enough light (at least 3 hours direct sunlight each day), seedlings may become weak and spindly which could reduce yields significantly.

Taking these simple steps will help ensure successful growth of delicious and nutritious arugula microgreens!

Prepare the Soil

Get your soil ready for planting by ensuring it’s well-draining and has a consistent moisture level – this’ll give your microgreens the best chance of success!

To do this, you need to add mulching soil and some soil amendments. Mulching will increase the water retention of the soil while also helping to keep weeds down. Soil amendments, such as compost, provide essential nutrients that are necessary for optimal growth. Mix them into the top few inches of your soil before planting to make sure your microgreens get off to a healthy start.

When adding these materials to the soil, be sure not to overdo it; too much can lead to drainage problems or nutrient imbalances that could stunt growth or cause other issues. You should also check the pH levels of your soil and adjust accordingly if necessary; arugula prefers slightly acidic soils between 6-7 on the pH scale.

Finally, make sure you prevent compaction in the area where you’ll be planting by loosening up any hard or compacted areas with a garden fork before adding more layers of mulch or other amendments.

With all these steps complete, you can now move onto actually planting your arugula microgreens! As long as you’ve taken care in preparing the right kind of environment for them – with plenty of well-draining organic matter and consistent moisture – they should thrive and reward you with tasty greens in no time at all!

Plant the Microgreens Seeds

Once your soil’s ready, it’s time to plant the microgreens seeds. To ensure their viability, make sure the soil temperature is between 65-75°F.

Sprinkle the arugula microgreen seeds over the surface of your pot or tray and lightly cover them with a thin layer of soil. You don’t have to press down too hard on the soil; just enough pressure to make sure that the seeds are in contact with the soil.

Then, water your arugula microgreen seeds using a spray bottle set at a fine mist setting and keep them consistently moist throughout their growth period.

You’ll also want to provide adequate light for your arugula microgreens when they start sprouting. The best way to do this is by placing them in an area with bright but indirect sunlight, such as near a window or outside in dappled shade if possible.

Make sure you rotate your trays regularly so that all sides of your plants get equal amounts of light each day.

It’s important not to overwater your arugula microgreens as this can cause them to rot and die off before they reach maturity. Check on them daily and only water as needed; once every two days should suffice if there isn’t much rain or humidity in the air.

Additionally, try not to disturb their roots while watering as this can also damage their delicate root systems and stunt their growth.

Harvesting time! After about 14 days, you should see small leaves emerging from beneath the soil—this is when you know it’s time for harvesting! Use scissors or kitchen shears snip off at least 2 inches above ground level and enjoy!

Arugula microgreens are known for having a spicy flavor, which makes them perfect for salads, sandwiches, soups, or garnishing dishes.

Water the Soil

Sprinkle some water on your soil to keep it moist and ensure your microgreens get the hydration they need. Applying a layer of mulch will help maintain moisture in the soil and reduce watering frequency.

When watering, make sure you use tepid or room temperature water, as cold water can shock the plants’ delicate roots. Be careful not to overwater, as this can cause root rot and other issues that could hurt your microgreens’ growth. Aim for light and consistent moisture levels instead of soaking the soil too much at once.

If you’re unsure about how wet your soil is, stick your finger into it up to the second knuckle – if it’s damp then the microgreens are likely getting enough water. Additionally, be sure not to let standing water accumulate in trays or containers for long periods of time as this could lead to fungus-like diseases in your arugula microgreens.

With proper moisture levels and mulch usage, you’ll be able to give your arugula microgreens just enough hydration so that they thrive!

Provide Adequate Light

Providing adequate light is essential for healthy microgreen growth. Studies have shown that microgreens can grow up to three times faster with the right amount of light. The best way to ensure your arugula microgreens receive enough light is by providing them with a combination of natural sunlight and indoor lighting.

When using natural sunlight, be sure to place the container in an area that gets bright but indirect sunlight throughout the day. If you don’t have access to natural sunlight, you can use fluorescent or LED lights indoors instead. For optimal growth, position the lights about 3-6 inches away from the top of the soil surface and leave them on for 14-16 hours each day. If possible, try using both natural sunlight and indoor lighting together as this will provide your arugula microgreens with a balanced source of light and help them grow even faster!

It’s also important to monitor the temperature when growing arugula microgreens indoors. If it gets too hot near the lights (over 80 degrees Fahrenheit), your plants may become stressed out and their growth may slow down significantly. To prevent this from happening, make sure there is sufficient air circulation around your containers so that they stay cool at all times. Additionally, keep an eye out for any signs of discoloration or wilting leaves which could indicate that either too much or too little light is being provided.

When growing arugula microgreens outdoors, be mindful of how much direct sunlight they are receiving. Too much direct sun can cause them to become dried out and wilted very quickly! Always make sure there is some shade available during peak hours so that they don’t get over-exposed to harsh conditions. And lastly – monitor your plants regularly throughout their growth cycle so you can catch any issues early on before they become serious problems later down the line!

No matter what type of lighting you decide to use for your arugula microgreens, it’s important that you provide them with consistent moisture levels throughout their entire life cycle. Otherwise, their growth rate will suffer greatly and they won’t reach harvest size as quickly as desired! Be sure to check in on them every few days and adjust accordingly depending on how wet or dry their soil feels at each inspection period. With these simple steps in place, you’ll be well on your way towards successfully harvesting delicious batches of freshly grown arugula microgreens in no time!
