The leaves on my lemon tree are dry and curling. They are indoors in pots. They have always lived in the hall very happily, but now the leaves are dry and beginning to curl and drop.
The curled leaves on your lemon tree may indicate a pest problem or an environmental issue. The following article will assist you in your diagnosis:

I have a very large lemon tree in my back yard that is about 10 years old. My mom bought it for me from a farmer's market. It produces large lemons every year, about the size of a grapefruit. They smell great like lemons should smell, but they taste awful! We can't use them for anything! Is there anything I can do other than chop it down?
What kind of lemon tree is it? How much water and fertilizer has it received? Is the tree showing any signs of stress such as yellowing leaves or fungal problems?
Has the tree never produced good tasting fruit? Since the tree has apparently been this way for a decade it could have been a problem with the rootstock - it may have taken over the crown. I think this may be the case due to the shape of your lemons. The variety of root stock for most citrus is "Sour Orange" which is very bitter, but it has the shape of a large orange, not a Lemon.
Barring that, it could also be the timing of harvest. Lemons that are harvested too soon will be overly sour. Those that are harvested too late will be overripe with little taste.

Roughly how much fertilizer to give a 15-plus year old lemon tree?
Basically the amount of fertilizer used really depends on how tall your lemon tree is. If your lemon tree is 20 feet tall, for example, you would apply fertilizer in a 20-foot circle around the tree to ensure that you reach the entire root system.

My lemon tree has dropped lots of little fruit. It never has before and we have been here 30 years and it was here then. We prune it every August so why is it dropping now?
Here is an article that explains reasons for lemon fruit drop such as environmental factors (sudden changes in temperature, heavy rains, etc.), insect pests, and more:

My tree is new and tiny and getting so many lemons I know it can't support them all. How many should I allow to mature?
Your lemon tree will go through a natural thinning process on its own without any intervention on your part. I foresee many of those lemons dropping on their own accord. As your tree matures it will be able to hold onto more fruit on its branches in the future.

As the tree blooms you can take off as many blooms as needed to keep the branches from breaking as the lemons mature. I have had to do this with a peach tree.
Are these new leaves starting to grow back cause they aren't thorns? Although there are thorns. Earlier in the winter I started losing all my leaves. They turned yellow and dropped off a lot of them. But it still flowered and I have plenty little lemons. But I just noticed these green things sprouting out. Are they something to be concerned about or are they the leaves growing back? Here's a picture - the one on the left is one of the bigger ones. It kind of sticks out from the rest of the tree along the branches.
I'm sorry we did not receive your picture.
Please let us know what type of tree you are referencing and send the picture.
I have a container grown lemon tree and it has done fairly well over winter and it produced fruit last year and is now showing signs of flowers again. I have been putting it outdoors as long as the temperature is above 50 but have to haul it in every night because we are still having lows in the upper thirties to low forties. My question is this, could I put an over sized clear plastic around it and pull it up at night to enclose the whole tree would that keep it warm enough? Thanks for your help.
Plastic by itself is not recommended to protect citrus trees from cold/mild freeze because it has the potential to transfer cold to the leaves and burn them. It is also not thought to be a good heat insulator. It is best to cover them with blankets or frost cloths - you could wrap plastic over the blankets as a second layer of protection.
I would recommend you review the section "How to protect growing citrus trees in cold climates" at the following link:
