Citrus Tree Feeding
What do I feed the orange tree and the grapefruit tree to ensure that the fruit is sweet? Does the same fertilizer work on peach, apricot, and nectarine?

A balanced fertilizer like 10-10-10 or 20-20-20 will be fine. Follow the directions on the package when applying, simply because different manufacturers have different application directions. Most home and garden centers will carry them. If possible, find a citrus fertilizer (you should be able to find them at garden nurseries) which will also make sure that micro nutrients are supplied.
