Hello, I've had a successful Jatropha for a few years now here in SoCA but since it didn't grow any foliage this spring I pulled it up and noticed it was too wet, so I took it out from its soil (I must have overwatered it in our drought) and let it and the soil dry. There is a soft spot on a portion of the lower bulb (in the photo it's where my thumb is, the dark spots are firm) - I'm sure from reading that it's root rot - is it too far gone? or can I cut off that section and let it harden off, or ? Any advice appreciated, I would hate to lose it!
Thank you....
