Are you saying the plant held the fruit but the fruit didn't grow over the course of a year? Or that the fruit got pea size and then dropped off the plant?

If the latter that would be typical of a young plant. If its holding the fruit but the fruit's not growing... very perplexing.

Yup, the tree held the fruit no problem, but it was tiny.

I found out what happened and I just wanted to share my experience.

We dug out the tree (thinking maybe the soil didn't have enough nutrients or something so we'd change it) and found at least 10 (TEN!!!!!) white worms. Didn't think much of it at this point.

The tree itself barely had any roots when we pulled it out (they were short and hair like), and obviously we thought that was very odd. We didn't think it was about the worms at all. We just thought the nursery gave us bad plants (hanging head in shame here).

Fast forward to a week ago when I decided to research it (at this point Im already looking for another Calamondin tree to replace the old one) and found out that those white worms were actually ROOT EATING MAGGOTS.

That explains why the fruit growth was so stunted!

Here is a photo of our calamondin tree, it's so dried out and you'll find a pic of a really small fruit.

I found out this can't be revived anymore, so I'll be looking for another tree.

My plant looks healthier than tis pant leaves are very green and has lots f fruits but very small.im sure it's not the lacking of water.but before I brought inside the house fertilized it with 10-10-10 and rained after that.im having lots of small fruits but they don't get big.what can I do?
