Cilantro seeds should be harvested for planting when the plant has fully bolted and the seed heads have dried out completely.
 
Here’s what tells you it’s time to harvest cilantro seeds for planting:
 

1. The Seeds Turn Brown and Dry

The most reliable sign of when to harvest cilantro seeds for planting is color.

When the seeds turn this brown color and feel dry to the touch, that’s your green light for harvesting cilantro seeds for planting.

Once cilantro flowers fade and seeds start forming, the plant naturally begins to turn yellow and brown.
 
The leaves will dry up, and the stems will lose their green color.
 
This die-back is a clear signal that the cilantro seed harvest window is open.
 
If you wait until the plant is mostly brown, you’ll know exactly when to harvest cilantro seeds for planting.
 

3. Seed Heads Rattle When Shaken

Another handy trick to know when to harvest cilantro seeds for planting is to gently shake the seed heads.
 
If you hear a soft rattling sound, the seeds are loose inside and ready to be collected.
 
This rattle means the cilantro seeds have dried enough for planting, and they’ll store well if you harvest them now.
 

4. No More Flowers Are Blooming

Cilantro produces tiny white or pink flowers that eventually turn into seeds.
