why have my orange and kumquat trees never flowered?
I fertilize 3 times a year, water deeply once a week and they don't seem to have any disease, just never a single flower in 8 years.

I would have the soil tested. It sounds as if there may be a nutrient imbalance--too much nitrogen/too little phosphorus. In order for plants to bloom or fruit, they need phosphorus. Bone meal is a great way to add this nutrient to the soil. Here is more information: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm
