Do I need 2 lime trees to produce fruit?
I live in zone 5, I bought a lime tree last summer. It did great outside and when I brought it in the house it flowered but never produced fruit. Now it is flowering again in a southern window. Do I need to buy another one to produce fruit and do I require bees to pollinate?

You do not need another tree to get fruit from lime trees, but you do need pollination. Here is more info: https://www.gardeningknowhow.com/garden-how-to/beneficial/insect-pollination-process.htm
If you would like it to produce fruit and help the pollination along, just take a small paint brush and swirl it around in the blossoms.
