I recently cleared out several bayberry trees and plan to replace them with figs, but I noted some of the roots of the bay berries had golf ball size tumors caused by nematodes. Are figs resistant or do I have to treat the soil?

Figs are very susceptible to nematode infestation. It may be best to grow them in pots of your soil is infected. __________________ California Central Coast Zone 9 Wish List: Figo Preto/Black Madeira, I-258, Genovese Nero

Plant an indicator species like Okra or something and see if it gets infested. The galls should be pea sized so it does not even sound like RKN. __________________ 7a, DE

Thanks for the info. From the size of the knots I am hoping it is a disease ofm the bayberries. I have a few weeks before the area is cleared and I'll have the county agent take a look at them.

Actinorhizal plants such as alder and bayberry can also form nitrogen-fixing nodules, thanks to a symbiotic association with Frankia bacteria. https://en.wikipedia.org/wiki/Root_nodule Do they look like this? http://web.uconn.edu/mcbstaff/benson/Frankia/EcologyMyricaceae.htm These are normal, nitrogen fixing nodules and are not from nematodes or disease. __________________ Zone 6, MO Wish list: Galicia Negra, De La Reina - Pons, Genovese Nero - Rafed's, Sbayi, Souadi, Acciano, Any Rimada, Sodus Sicilian, any Bass, Pons or Axier fig, any great tasting fig.

Don't I wish! These are on the roots of the bayberry and look like large knots. I'd include a photo but I guess there is a file size limit of 1M
