You may not be watering it enough. You need to make sure that the water gets all the way through the soil. If the soil is very dry, it may actually start to repel water. So enough water for another plant would not be enough to rehydrate this one. Give the soil a good, deep soaking at least once a week (in addition to regular watering) and that should insure that it gets enough water.

You should really harvest the ripe fruit for several reasons, the least of which is increased risk of tree damage during a storm or heavy winds with heavy fruit on the branches. Also, fresh fruit picked will last a long time under the right conditions. It doesn´t spoil so quickly if really fresh. And yes, the fruit will take some of the life out of the tree when it is trying to blossom for the next season. Hope this helps.

You do not need any special soil to plant them. As a general rule of thumb I tell people to get their soil tested before planting just so you can address any nutrient deficiencies before planting. You may also want to amend the soil with compost as plants in general like organic rich soil.

You can treat this with neem oil. It gets rid of both the fungus and the pests that cause the fungus. Here is more info on neem oil:

Q. Fertilizer for Citrus Trees

I would like the numbers that correspond to the correct ratio of nitrogen to phosphorus in grapefruit fertilizer. I used a 10-10-10 citrus tree fertilizer and there is a huge amount of rind compared to flesh.

A fertilizer with 16-5-16 or 16-5-20 should be effective for fertilizing citrus trees in your area.
