What is the best potting medium for a Citrus hystrix - key lime tree?
You can use a good quality potting soil that includes 25% compost or potting soil formulated specifically for citrus trees.

How long does it take to produce fruit?
According to the Univ. of Florida Extension website (https://edis.ifas.ufl.edu/ch092):
"Key lime trees propagated from cuttings or air-layers may produce some fruit within a year of planting. Budded and grafted trees usually produce fruit within three years, whereas seedling trees require another year or two before fruiting."
Unfortunately, I read the causes of leaves dropping after having over-watered my potted key lime. While a lot of leaves dropped, there are still some on the tree but it is really patchy and looks like a Charlie Brown key lime. Should I cut it back or just wait and see if new leaves come in? Thanks in advance for your help!
Make sure you allow the soil to drain and dry out.
Avoid stressing the plant and it should recover, unless the overwatering led to root rot.
To not prune or fertilize at this time.

I got a Key Lime Pie plant last week and replanted it this past weekend. Yesterday it did not have these holes in it, but today it has these odd holes on the older leaves. It is kept indoors near other plants. There are two cats in the house. I have watered it once since planting it. There are pebbles in the bottom of drainage. What could be causing these holes in my Key Lime Pie plant?
Can you describe the holes (size, shape, on outside of leaves or inside, etc.) or send a photograph? Is there any discoloration in the leaves?
It could be attributed to insects. I would examine the soil and the undersides of leaves for signs of insects.
It could also be fungal in nature. What soil did you use to pot your plant? Did you use sterile soil (potting soil)? You cannot use garden soil for indoor plants because it contains bugs and even diseases.
Bought the dwarf key lime tree last August. It was a 2 to 3 year old and doing very well. It started blooming last November. The flowers open up and fall off a couple of days. it is still blooming, but no fruit yet! What should I do?
Don't worry, it is common for young limes and other citrus to lose their flowers during the first few years. When they mature, they will start setting fruit, but they will still naturally lose the majority of their flowers (they produce more than they need).
Also, if you're growing indoors or if there are few pollinators in your area, you may need to hand-pollinate to increase yield:
Why is immature fruit falling off tree
This is a normal occurrence if there are too many fruits on the tree. They will overfruit to make sure that there are some good one's that remain on the tree. If all of them are dropping, I would look to a lack of light, fertilizer, or a watering issue.

It bloomed last year and had fruit. It was a beautiful tree, but a month after I brought it in the house it started not doing so good. It started losing its leaves and now it is a bare tree. The whole tree is still green, but I don't know what to do.
