Fig tree disease
I had two beautiful Black Mission Fig trees in my yard. First one, now the other developed a disease or fungus in which the leaves prematurely turned blackish-brown and died. When I cut down the first one, which did not re-leaf in the spring, the wood was dried and cracked throughout. Now the second, which appeared healthy earlier in the summer, is losing its leaves quickly and is oozing small areas of sap-like substance. I've resigned myself to losing the second tree as well, but I am wondering, what do I need to do to stop this from spreading to my citrus, and ornamental trees on my property? Can I treat the soil and plant some other kind of tree there? Thank you so much.
