Coriander After 16 Days

Coriander roots are now about 3.5 cm (1.5 inches) long. They have done well to make so much growth in 4 days at such low temperature.

This is a tap root system; it will be forming lateral roots soon. Since coriander comes from a hot dry climate, a taproot system is ideal to access deep water and nutrients.

Things are starting moving on top, now. The hooked hypocotyls have turned green and the cotyledons (seed leaves) are about to emerge from the seeds.


WHAT'S THE POINT?
The point I want to make by showing you all this is that seed development is deceiving. Were it not for the fact that we can see the roots, we would never believe they had developed to the extent they have. This is why novice growers over-water seeds: As the compost dries on the surface, they believe the roots are still too short to access water deeper in the compost. They are not.
