I have a Valencia orange tree full of fruit. The problem this year is that all the fruit is considerably smaller than in previous years, and it's falling at the rate of 4-6 per day. I find that some of the oranges are a little soft and discolored around the stem, and these pull off very easily.
I'm wondering if this isn't some type of fungus? The leaves look normal and so does the fruit, except for the size. I'm treating with wettable sulfur and hoping there might be a chance of saving part of the crop. Any input would be greatly appreciated!
