Big quince shrubs-(6-7 feet tall)may be 25 years old. Do not produce fruit, but do have beautiful flowers. Can I prune these to 3 feet?

You can prune them to 3 feet but they are going to look pretty ugly and will not bloom much until they regrow some. If you are going to prune them back, right now is the time to do the pruning work.
