I have dwarf container lemon, lime, and orange trees. They do not produce fruit, and I am wondering why. I give them lots of sun and water when I think they need it. I did have a lime, one that produced lots of limes, but then it died.
Ccitrus trees generally need 2-6 years before they are mature enough to fruit. Your trees may not be quite mature enough to fruit.
Another possibility is that the trees have too much nitrogen. This causes a lot of foliage to grow with little to no flowers and fruit. I would have your soil tested at your local extension office and then add some phosphorous to the soil to encourage blooming.
I am growing a citrus collection and there is a sticky substance on all the leaves, as though the plants are sweating. I also notice tiny little brown spots, like freckles up and down the limbs as well as underneath the leaves. Is that a pest or disease, and what should I do about it?
It is a pest called scale. This article will help:

Can I just plant my citrus tree right in the dirt in my yard?
If you live in the right zone for citrus, you can. It may not grow as well in some kinds of soils, but you can use the lasagna method to amend the soil over time.
We have a small garden in our home. Most of the fruit and fragrant flower plants are five years of age, one the average. Since last winter plants are drying up one by one. We have already lost some citrus and guava plants. Some flower plants, like Yasmin and Marwah, were also dried. Apparently, nothing seems to be wrong with them, especially no over-watering involved. Can you please help me know the reason and some ways to reverse the situation? Can the affected plants survive?
There are two things that I can think that may be causing this. Did you have a colder than usual winter? I know here, we have had unusually cold weather and it has killed many plants that did fine for years. Another reason may be unusually high winds. High winds can rapidly dry out plants, especially if they are not use to it. Do you have high winds? If so, this could be the problem.
What would cause our young citrus tree leaves to turn yellow? How can I remedy this?
It is most likely not taking iron up properly. This article will help:

My friend gave me her citrus plant when she moved away. I think it was not in good shape (the leaves were dry and falling off), but I thought I could nurse it back to health. About a year later, it is in even worse shape and I think it's a goner. After cutting it back, it now is only a stick about 5 inches long coming out of the soil. How do I know for sure if it's dead?
This article will help you figure out if it is still alive:

I have several beautiful citrus trees at home, yet the leaves are turning yellow; and on some of them, the point of the leaves are yellow with brown on the very edge--like if it were dry. I have used fertilizer for “citrus and avocado, ” but it seems that it's not working. Does it need more, or are my trees sick?
I would have the soil tested. It does sound like a nutrient problem, but there are several it could be and the only way to know which nutrient is lacking is to do a soil test.
