What’s the Best Fertilizer for Microgreens? A Complete Beginner’s Guide
Microgreens grow fast — and with the right fertilizer, they grow even better. Learn what nutrients microgreens need, when to feed them, and how Easy Harvesting's Microgreen Essential can supercharge your harvest.
Microgreens are small in size but big on nutrition. Whether you’re growing them at home, for a restaurant, or as a hobby — getting the right fertilizer is key to maximizing your harvest.
These tender greens grow quickly, often in just 7–14 days, which means they need the right nutrients available right from the start. This guide will help you choose the best fertilizer for microgreens and introduce you to a simple solution that delivers consistent, healthy growth.
Why Microgreens Need Fertilizer
Even though microgreens grow quickly and don’t require a deep root system, they still need:
Nitrogen (N) – for vibrant green leaves
Potassium (K) – for water balance and overall health
Micronutrients – like calcium, magnesium, and iron for resilience and color
In soil or hydroponics, nutrient depletion happens fast. A good fertilizer helps fill the gap so your plants grow evenly and don’t yellow prematurely.
Choosing the Right Fertilizer Type
There are three main types of fertilizers for microgreens:
Liquid Fertilizers – Easy to apply in water trays or directly to soil
Seed Priming Solutions – Boost germination and early vigor
Hydroponic Nutrient Mixes – Specifically formulated for water-based systems
Pro tip: Avoid using standard houseplant fertilizers. They’re often too strong and may lead to salt buildup or uneven growth.

How to Apply Fertilizer to Microgreens
For Soil-Based Growing:
Mix the recommended amount into water
Water gently from the base
Start from day 3–4 of germination
For Hydroponics:
Add fertilizer directly to the water reservoir
Replace solution every 3–5 days for optimal nutrition
For Seed Priming (optional):
Soak seeds for 4–6 hours in a diluted fertilizer solution
Rinse and plant as usual
