most fall off while fruit is very tiny. Why does this happen? What can I do to keep them on trees so they grow big into fruit?
This is perfectly normal for a young, and even sometimes and old tree! If the tree should be old enough to bear plenty of fruit and it does not, then they may need fertilization. In fact, in order to fruit properly, they need fertilization often.

My tree was kept in a greenhouse all winter in central Ms. It looked great and even had one small lemon on it. Al of the leaves fell off before we took it out. Now it’s outside and the top part appears brown with no leaves. But below it is sprouting new branches. Should I trim the brown branches off or leave them?
Only prune if it is completely dead. It sounds like it could have been too cold, too wet, or underfed.

I have moved my lemon tree outside for the first time this year. The the leaves have started getting what look like bleach spots. What could be causing this?
The move from inside to outside is causing sunburn on the leaves. You need to provide some shade till it can "harden off." Here is more:

Hello, I have a lemon tree that is less than two years old. Many leaves have fallen off, and now the tip of the tree is starting to wilt and shrivel. Would cutting off the dead tip promote growth, or is the tree destined to die? The dead tip is the very top of the tree. Thank you, Laura
It seems small for a two year old tree. Was it grown from a seed? You can go ahead and trim the tip off; it may encourage branching.
I am wondering if it is being overwatered. Here are some possible reasons for leaf drop:

It was healthy till i took it in the house for the winter. The top of the plant does not have any leaves on it.
It is probably the transition to indoors. Some leaf drop is normal. These articles should help:

The plant leave don't look as healthy as those bushes that are planted outside the caged area in the ground. Please advise what type of insecticide or what I should apply to the plant leaves???
Unfortunately, your photo did not come through. It sounds a bit like spider mites, but it would be hard to say without being able to see the damage.

Hi hope you can help been growing this lemon tree from seed for about 3 years.i have had lots of problems with spider mites and I think scale not over sure about overwatering and in the few days has lost a few leaves can you help please.
These infections are caused by the insects, typically. This is to be expected, and can be hard to correct.
I recommend fungicides or bactericides. There is quite a bit of overlap.
Make sure that the tree has plenty of time to dry out down to about 2 or 3 inches between waterings. This will help to make sure that it doesn't get overwatered.
Just as a personal tip. These trees will have a rough time unless you provide extra lighting, indoors. 100 or 200 watts of light will be sufficient, as long as it is horticultural grade lighting. Myself, I use a 315 watt CMH, or Ceramic Metal Halide. This lights a 4 foot by 4 foot area, comfortably. This fits my small potted trees for the winter, and keeps them growing quickly.
Another thing to mention- Iron sulfate, and Dolomitic lime will help you, tremendously. Once or twice per year and at any sign of infection, sprinkle a little onto the soil and it can help keep infections at bay, as well as condition the soil.
