Q.My Grapefruit Tree is producing smaller fruit lately and I would like to know if it is a fertilizer or watering problem?
Older, mature tree in Sun City AZ, which usually provides an abundance of large, sweeter grapefruit in normal conditions.

If the tree doesn't get fertilized once per month, then this will be the most likely case. This article will give you more information on why a grapefruit can fail to fruit properly: https://www.gardeningknowhow.com/edible/fruits/grapefruit/grapefruit-tree-not-producing.htm
