Oranges

My Valencia Orange tree is really loaded with fruit this year, and ripens in May. I have thinned them somewhat, but not nearly enough, and now it is too late. Citrus tend to produce a large crop one year and then nothing the next. If I can thin the oranges early enough, then I can have a decent crop each year. Usually, my citrus is blooming around the first of April, but this year they still aren't blooming; although, they are getting ready to!
