A Gardeners Forum Forums General Discussion The Plants and Flowers Forum Shrubs and Trees kumquat tree not producing

We have a potted kumquat tree which got overly dry one winter when we were overwhelmed with preparing to move and didn’t get to the watering soon enough as a result. Most of the leaves dried up, and many branches seemed dead, so we thought the tree had probably died. But we continued to water it just in case. It did grow new branches and leaves, and appears to be reasonably healthy ever since. However, it’s now three years later, and it has failed to give us any fruit since that time. It finally started flowering again, but the fruits mostly fall off while they’re still tiny.

Is this tree a lost cause, or is there something we can do to encourage it to fruit again? We do fertilize it, although possibly not quite as much as we should. Another possible issue is that it’s in the West sideyard, where it gets afternoon sun (reflected off the white side of the house), but not sun all day. Is it possible that it needs more sun than this to produce fruit? Our potted lime tree is in the same location, and it does produce some fruit. Any help or insight with this would be appreciated.

I also live in Ca, southern. I have a potted kumquat tree and summer is the worse for watering regularly for me. A lot of leaf drop this year. When you do fertilize, do you use a special fert for citrus? If it has leaves and growth I wouldn't give up on it. If your lemon tree is happy in the same spot then it is probably not a matter of light or lack of. Just the blooms scent is enough for me. The fruit is a bonus.
I wish I could help more. Maybe someone else will have better info for you.
