Q.Non fruiting tangerine trees
I have two 15 year old tangerine trees grown from seed planted in the garden. They are full of leaves and healthy but so far have never flowered or set fruit. They are in good sunshine from mid morning to dusk in Antigua, West Indies. Have you any tips to stimulate them to making flowers and fruit?

This will ultimately depend on the exact variety of tangerine that you got these from. Some will bear fruit that resembles the parent, while others will bear a much different fruit, or even not at all!
You can do something to help the process along, though. You can feed them a citrus fertilizer, dolomitic lime, and iron sulfate once or twice a year. This will ensure that they have what they need to fruit properly.
