Cotyledon Leaves

Noun | kädəˈlēdn lēvz/

The first leaves that appear from a cannabis seedling as it emerges from the soil. Also known as “seed leaves,” cotyledon leaves grow in pairs, although some plant varities may have three cotyledon leaves. As the plant matures, the leaves will fall off to make room for the other parts of the plant to continue growing.


The cotyledon leaves are the first leaves to show after the initial germination process takes place.

Don’t remove the cotyledon leaves from the cannabis plant; they’ll fall off on their own as the plant matures.
