Has flowers but won't produce fruit. What does it need to get the flowers to fruit?
If you are seeing blossoms but you get no fruit, this is a pollination problem. You can hand pollinate with a small paintbrush. Just go from flower to flower and swirl the brush inside the blossoms.
Also, have you fertilized? Nitrogen encourages leaves to grow, but not fruit. Too much can actually keep a plant from producing fruit. This article has information on how to fertilize your trees: https://www.gardeningknowhow.com/edible/fruits/citrus/fertilizing-citrus-trees-best-practices-for-citrus-fertilizing.htm
I would also try giving it some phosphorus rich fertilizer like bone meal. If it is lacking phosphorus, it will not be able to produce healthy blossoms (which means no fruit.)
We purchased our lemon tree about a month ago and it was in full bloom. We kept it in the house for about three weeks until it got warm enought (75 +) outside in a container that is about 15- 20 gal. We used POTTING MIX to plant it in the container instead of potting SOIL. We also have a saucer under the planter to retain any excess water that drains after watering. Did I make a mistake in using potting mix instead of potting soil and should I not let excess water sit in the saucer? Is water soluable fertilizer best? I might add that we live in New Mexico, so we have very low humiditiy. Since putting the plant outdoors, all the blossoms have fallen off as well as some leaves.
They can tolerate a range of soils as long as it's well draining and slightly acidic. I would not allow it to sit in the water as this can eventually lead to root rot. Instead, allow the water to flow freely from the container. You can, however, set the container on a pebble tray filled with water to increase humidity or mist the plant daily. As for fertilizing your lemon tree, water soluable is fine. This article has additional information: https://www.gardeningknowhow.com/edible/fruits/lemons/learn-about-fertilizer-for-a-lemon-tree.htm
The blossom and leaf drop is normal, as the tree is acclimating to the outdoors and should right itself.
I live in zone 5, and I purchased a Meyer lemon tree two years ago (I believe it was less than 1 year old when I purchased it). I have it potted, and during the summer it goes outside to a full sun location. It gets approximately 10-12 hours of sun per day. I noticed this year it started to produce fruit. I was so happy to see it. Low and behold, a week or two later, the tiny little lemons turned yellow, than brown and fell off of the tree. Why did this happen, and how do I get it to produce fruit? I was at the store where I purchased it from, and they had more of the same trees from the same grower. They were all less than 1 year old, and I noticed one tree had two good sized lemons on it. What am I doing wrong?
Most citrus trees will shed fruit if they do not have the nutrients and/or water to support the fruit. I would have the soil tested. Also, the fruit may not be developing due to a lack of phosphorus or poor pollination. This article should help: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-fruit-drop.htm
What causes the Meyer lemon fruits to turn black when young?
This could be due to poor pollination, especially if it's been hotter or wetter than normal. If you are noticing fruit drop, this article may also help: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-fruit-drop.htm
I have fungus and mites on my grapefruit tree and fungus on my Meyer lemon. Both have been sprayed once. Fruit has brown bottoms. Should I remove fruit from tree or will it be ok to ripen?
Treat with neem oil, which should take care of both the fungus and the mites. The affected fruits can be removed and discarded. Here is more information: https://www.gardeningknowhow.com/edible/fruits/citrus/citrus-mite-problems.htm

Currently my Meyer lemon tree is fruiting and flowering. It is in a container about 450mm dia x 350mm deep and the tree is 800mm high. I am looking at putting it in a half wine barrel.

I would recommend wating until the tree has finished its flowering and fruiting as repotting now could have an adverse affect on this. If you repot it, it is likely the fruit will be discarded by the plant. Fruit trees will abort their fruit first when they come under stress and transplanting is always stressful for a plant.
It is flowering and the flowers are falling off. I have a plant light on it for 8 hrs a day and I water according to a moisture meter but the leaves are still turning yellow and are cupped. What am I doing wrong and will I still get fruit? Any help would be appreciated. Thanks, Michael from NY

Most citrus have many more blooms than the plant could ever support if pollinated. In fact, a lot of immature fruits often fall off because the plant can't support the blooms that did get pollinated. This is a normal, self-preservation trait.
If the leaves are turning yellow, are you feeding a well balanced or cirtus food acccording to package directions? And, I've found a moisture meter all but useless. I prefer to check soil moisture with my fingertips about 4" down, or by "weight".
