I recently downloaded articles on grafting citrus trees. My daughter has a miniature Naartjie (tangerine?) and I decided to try my luck on one of my new lemon trees. In undercutting the bud, I found that in every case there was a thorn above the bud, so I took the thorn as well but cut it off. Then according to the article, I grafted it using the inverted T method into the lemon approximately 12 cm from the soil level. Did I do the right thing? I want to have a go at grafting a lime bud onto another lemon tree. I have grown lots from pips.
Yes, this should be fine. As there is an open wound though from the removed thorn, I would treat the area with a fungicide, to help prevent rot.
I purchased a lemon tree from the Tampa Airport gift shop back in 2008. It was one stalk with a few leaves. Now it has grown into a beautiful lemon "bush". It is approx. 1 foot high but very full like a bush. It has never produced any lemons. The leaves smell very fragrant with a lemon scent and the bush has a lot of thorns.
I live in Michigan and it is brought indoors for the winter months. I also have used citrus dirt when replanting my lemon tree to a larger container. I also have read to add coffee grounds occasoinally to help, but so far no luck. No blossoms and no lemons. I am not sure what brand of lemon tree this is, but was hoping for any advice you can give to help me produce lemons. Thanks!
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 blossoms (which means no fruit.)
The requirements for lemons are very similar to that of limes. If you have not read it yet, this article may also be helpful: https://www.gardeningknowhow.com/edible/fruits/lime/reasons-and-fixes-for-lime-tree-not-producing-blossoms-or-fruit.htm
I live in Colorado. I have a now 20-inch tall Lemon tree in a 6-inch wide by 4-inch deep pot in the coolest, sunniest room in the house. How do I care for it? What kind of pot should it be in? What size and depth and what kind of soil (as well as watering habits) does it require as an indoor house tree.

The tree has a small lemon. Little black flies about the size of fruit flies all around. What should I do? They seem to be coming from the soil or resting in the soil. They become active when I water the tree.
Sounds like fungus gnats. This article should help: https://www.gardeningknowhow.com/special/children/fungus-gnats.htm
I live in AZ. I have a lemon tree in a pot. The leaves are curling. Does this mean I am underwatering or overwatering?
You may not be watering it enough. You need to make sure that the water gets all the way through the soil. This article will help with watering your tree: https://www.gardeningknowhow.com/edible/fruits/citrus/tip-on-water-requirements-for-citrus-trees.htm

As for insecticide, we would suggest using neem oil. It is safe to use, is very effective against insect pests and also serves as an adequate fungicide. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I have been given a lemon tree on a frame - it is thriving in my conservatory but I wonder if it would be better released from the frame work??
Normally fruit trees on a frame need some amount of pruning maintenance to remain espaliered (pruned flat against a wall or frame). This maintenance does not harm the tree, but can be time consuming, and annoying if you are not keen on the tree being like that in the first place.
If you want to keep it espaliered, there will be no harm to the tree. Basically, just prune away any growth that is outside the frame shape.
If you are not keen on the espalier shape, you can just let the tree resume its normal growth pattern and then use standard citrus pruning.
