I am in Central Florida, 9b, fairly sandy soil. I have 4 poms, 2 Wonderful, 1 Red Silk, and one Russian something or other. They are mulched and watered 3 times a week although I drop to 2 in the winter. All are at least 4 years old with the oldest Wonderful being 6 and being around 7 feet tall and at least 4 feet wide at the top. I keep the shoots trimmed back, usually every couple months.

The problem is I am lucky to get a flower or two off of all of them combined every year. How long until they start flowering and holding fruit? What can I do this winter to make them productive or improve on them?

From what I read, your watering is an issue.
Keep it on the dry side when the flowers emerge.
This happened to me past Spring as well. We had a lot of rain and many flowers that were on the trees dropped .

This is how Paradise suggests to do it

@Bluetangcian, I would contact the nearest Florida County Cooperative Extension Office and ask a local Master Gardener how to increase pomegranate fruit production. Cooperative Extensions offer research based information to help growers and hobbyists increase crop production. You can find the nearest office at this link: http://sfyl.ifas.ufl.edu/find-your-local-office/

This FL Cooperative Extension publication says, "Pomegranate trees are self-pollinating. Severe fruit drop during the plant’s juvenile period (3‒5 years) is not uncommon. Fruit drop is aggravated by practices favoring vegetative growth, such as over-fertilization and excess irrigation. Avoid putting young trees under stressful conditions. Fruit drop is less severe on mature trees than on younger trees." Since your trees are 4 years old -- nearing fruiting age -- I would strive to water for fruit production. https://edis.ifas.ufl.edu/mg056

"Water use directly affects pomegranate yield and fruit quality. The frequency of irrigation depends on several factors, such as temperature, rainfall, type of soil, and age of trees. During the dry season, for trees planted in central ridge sandy soil, growers irrigate only once per week for 15-20 minutes for trees less than one year old, and twice per week for about 60 minutes each time for trees more than 2 years old. In areas with clay soil, growers often do not need to irrigate their trees. Over-irrigation can cause fruit split. The optimal irrigation practices for pomegranate trees require further research." https://edis.ifas.ufl.edu/fe1024

"The University of Florida is collaborating with Florida pomegranate growers in experimental trials to identify optimal cultivars suited for Florida. The preliminary results show there are some yield merits in the Girkanets, Kazake, Wonderful, Al-sirin-nar, and Medovyi Vahsha varieties (Castle and McTeer 2016)." https://edis.ifas.ufl.edu/fe1024

Fingers crossed, next season your poms should begin to produce pomegranate crops!

Ill aim the sprinklers away or put in the mushroom style sprinklers to reduce the water they get. We had a relatively wet summer and spring this year so maybe that had something to do with it. Unfortunately its on a circuit which has citrus, avocado, azalea, Sausage tree and jujube, some of which are water hogs so if we have a dry spell during the important time period I cant just turn it down.
