Whether you’re living in a city apartment or just starting your microgreens journey, arugula microgreens offer the perfect combination of fast growth, exceptional nutrition, and bold flavor that makes home growing both practical and delicious.

Arugula Microgreens Nutrition: A Nutritional Powerhouse

Understanding arugula microgreens nutrition reveals why these tiny greens have become a favorite among health-conscious urban gardeners. Research shows that microgreens can contain 4-40 times higher levels of vital nutrients compared to their mature counterparts, making them an incredibly efficient way to boost your daily nutrition intake.

How to Grow Arugula Microgreens: Step-by-Step Guide

Learning how to grow arugula microgreens is straightforward once you understand the basic principles. This comprehensive guide will take you through each stage of the growing process, from setup to harvest, ensuring you get the best results every time.

Step 1: Gather Your Supplies

Essential Equipment:

• Growing trays (5″ x 5″ minimum)
• Drainage trays or holes
• Growing medium (potting soil or coco coir)
• Arugula microgreen seeds
• Spray bottle for misting
• Blackout cover (plate or tray)
• Clean scissors for harvesting

Step 2: Prepare Your Growing Tray

Start by ensuring your tray has adequate drainage. Pierce 6-8 holes in the bottom if using aluminum trays, or use trays with pre-made drainage holes. Fill the tray with about ½ inch of your chosen growing medium, creating a flat, even surface that’s crucial for uniform growth.

Pro Tip: Lightly press down the growing medium to eliminate air pockets, but don’t compact it too firmly as roots need room to breathe.

Step 3: Sow Arugula Microgreen Seeds

Unlike many other microgreens, arugula microgreens seeds should NOT be soaked before planting. Arugula seeds are mucilaginous, meaning they develop a gel-like coating when wet, which can actually hinder germination if pre-soaked.

Seeding Instructions:

• Use 1-2 teaspoons of seeds per 5″ x 5″ tray
• Sprinkle seeds evenly across the surface
• Gently press seeds into the medium
• Don’t cover seeds with additional soil

Seeding Density Guide

Proper seed density is crucial for healthy growth. Too dense and plants compete for light and nutrients; too sparse and you waste growing space. Aim for seeds to be nearly touching but not overlapping.

Step 4: Initial Watering and Blackout Period

Immediately after sowing, mist the seeds thoroughly with clean water until the growing medium is damp but not waterlogged. The goal is to provide enough moisture for germination without creating soggy conditions that promote mold growth.

Step 5: Light Exposure and Care

When sprouts reach about ½ inch tall (typically day 3-4), remove the blackout cover and introduce them to indirect light. This is when you’ll see the dramatic green-up process as chlorophyll develops in the leaves.

Lighting Requirements:

• Natural Light: Bright, indirect sunlight
• Artificial Light: LED grow lights 12-16 hours daily
• Location: South or east-facing window
• Avoid: Direct sunlight (causes wilting)

Step 6: Watering During Growth Phase

Maintaining proper moisture levels is critical for healthy arugula microgreens. The key is consistency – keeping the growing medium moist but never waterlogged.

Step 7: Harvest Your Arugula Microgreens

After 8-12 days, your arugula microgreens will be ready for harvest. Look for these signs: cotyledons (seed leaves) are fully expanded, plants are about 2 inches tall, and the first true leaves may be appearing.

Harvesting Steps:

1. Stop watering 12 hours before harvest
2. Use clean, sharp scissors
3. Cut just above soil level
4. Rinse gently in cool water
5. Pat dry with paper towel

Frequently Asked Questions

How long does it take to grow arugula microgreens?

Arugula microgreens typically take 8-12 days to grow from seed to harvest. They’re ready when they reach about 2 inches tall with fully developed cotyledons (seed leaves) and possibly the first true leaves appearing. The exact timing can vary based on temperature, light conditions, and growing environment.

Do arugula microgreens need to be soaked before planting?

No, arugula microgreens do not need to be soaked before planting. In fact, soaking is not recommended for arugula seeds because they are mucilaginous, meaning they develop a gel-like coating when wet. This coating can actually hinder germination, so it’s best to plant them directly on moist growing medium.

What do arugula microgreens taste like?

Arugula microgreens have a zesty, peppery, and nutty flavor profile. They offer the characteristic spiciness of mature arugula but are much milder and less bitter. The young leaves provide a fresh, clean taste with subtle earthy undertones that make them perfect for adding a gentle kick to salads, sandwiches, and various dishes.

Are arugula microgreens nutritious?

Yes, arugula microgreens are extremely nutritious and considered a superfood. They contain 8 times more calcium, 5 times more vitamins A, C, and K, and 4 times more iron than iceberg lettuce. They’re also rich in antioxidants, contain 20-25% protein, and provide all essential amino acids, making them one of the most nutrient-dense foods you can grow at home.

How do you harvest arugula microgreens?

Harvest arugula microgreens by cutting them with clean scissors just above the soil level when they’re about 2 inches tall. Stop watering 12 hours before harvest to ensure the greens are dry. After cutting, rinse them gently in cool water, pat dry with paper towels, and use immediately or store in the refrigerator for up to one week.

Can you grow arugula microgreens without soil?

Yes, you can grow arugula microgreens without soil using hydroponic methods. Popular soil alternatives include coconut coir, hemp fiber mats, paper towels, or specialized growing pads. These soilless mediums work well for microgreens because the plants rely on stored seed energy for growth and don’t require the nutrients that soil provides for longer-term plants.

Why are my arugula microgreens growing unevenly?

Uneven growth in arugula microgreens is usually caused by inconsistent seed distribution, uneven watering, or poor light exposure. To fix this, ensure you distribute seeds evenly across the growing surface, level your growing medium, water uniformly, and rotate trays regularly for even light exposure. Proper seed density is also crucial – seeds should be close but not overlapping.
