So yesterday I was working at some condominiums I maintain as a landscaper in Pacific Beach San Diego. Im weeding around a street planter when I see them. Coralloid roots with the nearest Cycad a Cycas Revoluta at least 7 feet away! The crazy thing is it had to go underneath a curb and sidewalk to pull it off😳Is this normal? Here is a pic of the roots and the Sago in the distance.

    Yes, while surprising, I find coralloid roots all over my garden at a similar distance from any Cycads.  Some are isolated by paver walkways about 3 feet wide from the closest Cycad.

    I have drip irrigation and find coralloid roots near the emitters of palms and other non Cycad plants.   If you search for posts with "coralloid" in the title, you will find a string I started a few years back with some examples of stray coralloid clumps.

    Good question, only a true grower would ask that question!
