TOPIC: Small Round Balls On The Roots

Small Round Balls On The Roots 1 year 1 week ago #34995

Hi all
I've had 2 Buddhist Pines (Podocarpus) and the both died really suddenly, I've recently got a larger one but all three have these small balls attached to the roots (see photo) can't see anything online about them, so wondered if anyone on here has come across them before?

Thanks for your help

yeah, they contain nitrogen fixating bacteria. Very normal on roots of specific plant species.

I agree with Leatherback. These balls are called nodules and allow the plant to absorb gaseous nitrogen from the atmosphere. They are caused by a symbiotic relationship with bacteria. I've worked on a research project to develop chemicals that facilitate this relationship in soy plants.
