I live in New York City and have a three-year-old fig tree. It bore fruit for the first time this year, but it failed to ripen. Why? What is a good fertilizer?
A good garden fertilizer, such as 5-10-5, used at the rate of one pound per 50 square feet, will probably supply sufficient nutrients. However, in northern states, fig trees need heavy protection during the winter and usually bear little fruit. Check with your local fruit growers or your local extension service to see if your cultivar has a good track record in your area.
