Delayed fruit growth
I've an indoor tomato plant, but this one fruit did something a bit odd.
I pollinated it. A few days later the flower fell off, but the fruit never grew. The fruit just sat there, for about 2 months, not growing. All the other fruits generally started growing shortly after pollination.
It looked like the right portion of the image.
The plant is quite healthy, and I have to prune it. I almost this off.. but left out of curiosity.
A few days ago the side started to bulge, and is now the size of a grape. Any idea what might cause this to happen?
