Cilantro is prized for its distinctive flavor, but it is not a fast first-tray crop. The seed is actually a dry fruit that can contain more than one embryo, and germination is slower and less uniform than many brassicas.
Choose seed sold for microgreen use
Untreated seed with good germination is important for a crop that already has a longer production cycle.
Understand whole versus split seed
Cilantro seed may be sold whole or mechanically split. Split seed can hydrate and germinate more uniformly, but either form needs consistent moisture.
Use a shallow sowing and good contact
Spread seed evenly over moist media and press gently so the seed remains in contact with the surface.
Expect a longer germination window
Do not discard the tray simply because it lags behind radish or broccoli. Maintain stable moisture and temperature while the seed establishes.
Give the canopy strong, even light
Once emerged, cilantro benefits from good light and gentle airflow so stems do not become weak.
Harvest when aroma and leaf development are right
Cilantro can be harvested at the cotyledon stage or allowed to develop further for more recognizable foliage and flavor, depending on the intended use.
