Citrus fungus and mites
I have fungus and mites on my grapefruit tree and fungus on my Meyer lemon. Both have been sprayed once. Fruit has brown bottoms. Should I remove fruit from tree or will it be ok to ripen?

Treat with neem oil, which should take care of both the fungus and the mites. The affected fruits can be removed and discarded. Here is more information: https://www.gardeningknowhow.com/edible/fruits/citrus/citrus-mite-problems.htm
