Title: Barren Tangerine Tree
Post by: clarke on December 01, 2020, 07:16:10 PM
The tree was planted three years ago.  Last year, it was full of fruit.  This year no flowers, no buds, no nothing.
I fertilize, water, etc.
Any advice would be appreciated. Thanks.

This could be the beginning of an alternate bearing pattern. This is initiated when excessive fruit are produced in a "on" year which depletes the tree's nutrition reserves. In an effort to protect itself, little, or no fruit is set in the subsequent year. This is in turn followed by yet another year of excessive fruit set.
The cycle can be broken by thinning the immature fruit early in the season during the "on" crop year. Regular annual bearing can be re-established by keeping on top of this each year.

Excessive cropping is capable of outright killing overbearing plums and persimmons.

I have lost 3 peach trees this way.

I also think the tree is alternate bearing, having on and off years. You wrote that you fertilize the tree, however the leaves are showing a magnesium deficiency.  Look at the analysis of the fertilizer you are using, to see if it contains magnesium (Mg).

Why you are netting it?  Even with predacious squirrels, rats and lots of birds around here, my citrus (moro BO, rio red GF, various kumquats, meyer lemons, etc.) aren't bothered (as opposed to my figs, peaches, pomegranates, persimmons that get ravaged).
