Hi! I am growing a few different fruit bearing plants in our parking lot at the office. I have two fig trees, which are thriving, but my kumquat is in major trouble.
I bought it 2 months ago and it was just an exuberant bush about 2 feet tall and 2 feet wide at that time, with lots of leaves and a tons of mini kumquats just starting.
I planted it in regular organic potting soil in a self watering container, which was at least twice the size of the 3? 5? gallon container I had bought it in.
At first it seemed to be doing OK but soon started dropping lots of fruit. I looked up the problem and saw mention that it is normal for a bush to drop a good portion of its fruit if it will not be able to support it all.
Then it started dropping leaves and it has been dropping leaves for a month now. Most of them drop off while they are still entirely green. Some of them have large brown blotches on them. Some of them fall off with the stem and on others just the main leaf fell off, with the little stub remaining on the branch (unless those are from fruit that dropped).
I have not let the container go dry. There is a large container at the bottom, so it always has plenty of water, though I do not have to water it anywhere near as much as my fig trees.
I have left all the leaves and dropped fruit in the top of the container as I assumed it would just deteriorate and be "fertilizer" but maybe I should have been picking up the fallen fruit. Right now it is not dropping fruit anymore, but the leaves are still dropping every day. Now there are sections of branches which have no leaves at all left.
Does anybody know where I am amiss here?
I am trying to grow all the plants organically, so if somebody knows what is wrong and could propose an organic solution/remedy that would be fabulous.
I am in Los Angeles, Zone 10. Plant is out in the lot near a fence and is getting sun for most of the day.
