I have a grapefruit tree, which is nearly 16 years old. I do take care and prune it just before it starts to flower in Feb/Mar. Now since two years, I am finding the pink color which it had in the fruit is becoming pale. I do sprinkle Epsom salts now and again, but it did nothing. What else I can do?

I would recommend that you have the soil around the tree tested. Color loss can be linked to lack of micro nutrients in the soil, and if you do not regularly fertilize, then the soil can be lacking in some nutrients. A soil test will help you pinpoint what exactly the soil is lacking and amend it accordingly.
